Great Product 0 people found this helpfulAs usual, a great product and outstanding customer service from DK Custom Products. I installed on my 2020 Softail Slim and fabricated a small tab to mount the clamp so I can remove the catch can easier to service.

Great product 0 people found this helpfulI purchased and installed the catch can in 9/2025. I then took at 2400 mile trip. I checked it this past weekend to clean and inspect. It performed as expected. I am happy with it. No more oil in my V&H Insight filter.

External breather 0 people found this helpfulStill trying to find long enough breather bolts with nipples. So I have not installed it yet. Looks to be a great product.

Good Quality Kit 0 people found this helpfulEasy to install and no more oily crap fed into my engine. It looks good, too.

Easy Fix 4 people found this helpfulAs long as I can remember I’ve been getting oil misting on the right side battery cover on my FXLR. After checking out different options I decided on the DK Customs external breather system. I’m glad I did. I don’t usually put much faith in customer reviews since often it’s obvious it was written by someone affiliated with the product who also delete reviews critical of the products. In reading reviews of the external breather system by DK I found excellent tips on installation, along with both good comments and critical ones. Upon receiving the product I found what several reviewers mentioned easy installation with the hardest part being where to place the can. My original thought when ordering it was to put it straight down from the air cleaner, but with the Screaming Eagle Ventilator set I have there was no place to securely fasten the can. Fortunately I also ordered the optional clamp. One reviewer mentioned drilling holes in the backing plate (using increasingly larger drill bits) along with compression springs instead the hose clamps. These tips give it a much cleaner finished look. I’ve put several hundred miles on the bike since installation with zero oil misting visible. I’ve also found that throttle response and torque were much better at certain RPM’s. Do yourself and your bike a favor, get one of these!

Overpriced for what you get 3 people found this helpfulI have a Haritage, the instructions were less than complete for my install. That being said a quality job on making the catch can. Would be nice to include a couple rubber grommets to route the hoses through. A bit overpriced for what you’re getting but I suppose you’re paying for the idea which absolutely works.
Response from store
Thanks for your feedback! We're glad you like the quality and effectiveness of the catch can. I am sorry if you feel the instructions aren't complete or clear for your specific installation, and we’ll keep that in mind for future updates. Thanks again for sharing your thoughts and for your business! MB -
EBS 2 people found this helpfulEasy to install. Incredible customer service for any and all questions. Installing an EBS is a no brainer. Why have hot, oxygen depleted air and potential oil recycled back into your cylinders.
-
Excellent 1 people found this helpfulI wanted a different look, so I bought a 1/4 x 1/4 x 3/8 tee. Looks great! Very pleased with my purchase.

Install on M8 2 people found this helpfulI put one of these on my Dyna and now have installed one on my M8. Had an issue with getting the 1/4 inch fittings into the supplied 7/32 hose. No one else seems to be complaining about it so it must just be me. However, I obtained some 1/4 hose and proceeded to install the system. DKCustom did caution me that the 1/4 might back off from the air cleaner nipples. On both the Dyna and the M8 I used enough hose so that the air filter is contacting and pushing the hose onto the nipples. I've had no trouble with this. The Dyna Screaming Eagle cleaner needed one hole drilled for running the hose. The M8 114 Harley setup required two holes. As with the Dyna, I snuck up on the hole size until the hose would barely fit the hole so that it is tight enough that no sealant is required and it will not move on its own either. Different hose manufacturers will have hose labeled the same size as the other guy but the hose can be slightly different in size so you will need 32 and 64 inch bits to get a tight fit. Sneak up on it. I used 11mm and 14mm spring hose clamps instead of the supplied hose clamps. Couldn't find a spot I liked for the can near the air filter as as I did on the Dyna so I hung this one on the LEFT side saddlebag crash bar because I didn't want it so close to the 2 into 1 pipe on the right. These units are plain and simple (which always works best) and they do the job as advertised. On both bikes, the idle is smoother and the throttle response is crisper. This is a 'Must Do' if you want your bike to run better and have your air filters last longer. The reason for only a 4 star on the quality is only because I am not satisfied about the hose and the hose clamps that were supplied. The 'catch can' is perfect and is the primary item here so don't be put off by the hose or clamps. You can easily upgrade those items. It took me more time to figure out where I wanted to hang the can and run the hose than the install job required. Just make sure you've got it all figured BEFORE you start drilling holes and you will be pleased with the result.

EBS with catchcan 2 people found this helpfulReceived the parts read the instructions, and put on the EBS very easily. Great customer service and great quality of parts. I highly recommend DK Customs.

Do it. Now. 4 people found this helpfulInstalled it on my 2015 Dyna. I just placed an order for another one to put on my 2018 Ultra. The cotton filters on the Harley air filters tell you to not oil them. Why? Because they oil themselves with all the blow back from the two breathers. If you've got the ability to pick your nose you can install this yourself. I only rated this a 4 star because the provided hose clamps are not custom. I ordered a selection of 'spring band' hose clamps from Grainger because I wasn't quite sure of what sizes I'd need. These clamps ARE custom and look MUCH better than the hose clamps that come with the kit. I ended up using 11mm for the small (as many as 6 may be required) hose. 10mm may be a better fit but none were in the kit. However, the 11s are sequre. 16mm work fine on the larger hose. My setup required ONE hole to be drilled. I finished it to 23/64. This required forcing the hose through by hand and then pulling it through with a pliers. This made for a tight fit so that I didn't feel the need to use any sealant around the hole. You may wish to use a slightly larger hole but remember, you can make it larger if needed but you can't make it smaller if you mess it up. As others have commented, a rubber grommet SHOULD be supplied with the kit. The spring bands should also be supplied instead of the hose clamps. Otherwise...it's not CUSTOM. I discovered that a 16mm box end wrench fits the top part of the breather very well. In summation, do your bike a favor and put one of these breathers on your bike YESTERDAY.

Cleaned up exhaust pipes 3 people found this helpfulRemoving that blow by from the system has cleaned up the carbon from the outlet of the exhaust on my 2019 tri glide. I havent checked the catch can but I am willing to bet that it will have residue. I purchased a used OEM air cleaner and drilled it for the installation and saving the original

Excellent product, excellent customer support 4 people found this helpfulI purchased the external breathing system with catch can from DK Customs. The instructions were great and I had it installed w/n an hour. The difference is readily noticeable and any questions I had were effectively resolved with their customer service dept. I would strongly encourage everyone with a Harley to utilize this system to prevent blow bye in their throttle body and pistons

Catch can & breather system for Twin Cam 1 people found this helpfulTook a little more time than I expected to install but once done seems to work fine. I have to check & empty excess oil from catch can more often than I expected but system has eliminated oil blow-back from accumulating and leaking from my air filter.
-
works 1 people found this helpfuleasy to install. I put catch can right under air cleaner. It looks as if the bike came from factory with it. No more oil and hot moist air going into engine. That is a plus for the engine. Wish in knew about this sooner.
-
Excellent product 2 people found this helpfulNoticeable difference in performance and idling. Installed on my 09 Heritage classic, took longer to figure out where to hang the can than the install, super easy. Engine also running cooler just as presented. Wish I would have installed sooner. Ordered another one for my 22 Road King to head off the carbon build up early,

Breather releif 1 people found this helpfulI did a lot of research before purchasing this system. It did take some thought about how I wanted it installed and how I would route the hoses. The Screaming Eagle backing plate would need to be drilled for the hoses but I had a different Stage 1 filter that did not require drilling. The burning smell of oil is finally gone.
-
Excellent 0 people found this helpfulI continue to be a happy customer of DK Customs. Every product I’ve ordered has been more than I’ve expected. Even when calling in and speaking to them they are awesome with their customer service and guidance. Thank you DK Customs.

DK Custom Products catch can. 1 people found this helpfulI ordered this catch can system for my 2009 HD Electra Glide after reading reviews online regarding the oil blowback and the moisture condensation that’s going into my engine. After careful consideration and evaluating all the products on the market, I found this one to be the best and I am very happy with this product! Easy installation, and very successful in catching oil coming out of the breather box plus moisture condensation. Thanks for the great product!!

Easy install 1 people found this helpfulPurchased the kit for my 2022 Tri Glide, with only 2300 miles on it. I didn't like the idea of hot oily air being fed into the intake. the install was straightforward , and the included instructions were good. With no baseline temps, I won't be able to tell if there is a change. But, at least there won't be oily, hot air being sucked into the cylinders.
-
Good product 1 people found this helpfulEasy to install and gets that oil out of the intake.
-
Immediate Difference 1 people found this helpfulQuick easy install wish I would have done this a couple months ago .. I noticed immediately that the bike was idling smoother and the Throttle response was a little more dynamic ... must be something to that "CleanAir" after all ha ha ha ...

Love it. Great Value. Good for the bike 0 people found this helpfulJust installed a catch can External Breather System on my new 2022 Heritage FLHCS. Only have about 400 miles on the bike, but I wanted to take advantage of the benefits of the EBS system (reduce carbon build up and put clean, cool air into intake). This is my second EBS install. Put one on my 2018 Heritage when the 2-year warranty expired in 2020. Didn't want to wait to get the benefits of the EBS on my new ride. THANKS DK Custom Products.

External Breather System w/ Catch Can Harley Twin Cam & M8 1 people found this helpfulThis is installed on my 2022 Road Glide special. Takes about 10 minutes to install. Would be shorter time but I had to drill a couple holes and apply some Silicone. Attached to billet catch can this vent to atmosphere system looks and functions like factory works. Love it!
-
Perfect 0 people found this helpfulNice product, fit nicely on my Roadglide, my install was easy, routed the hoses so you would have to look hard to find it.

External breather can 1 people found this helpfulProduct looks great and is doing exactly what it was supposed to do, keeping oil and moisture out of the carburetor intake. Very easy install on 2018 Road Glide even with Screamin Eagle intake.
-
Excellent product 1 people found this helpfulInstalled this on my 2021 FLTRXS and the install was pretty easy. It’s a well thought out design that seems to work great! No more dirty oil going in my intake. Verified this after riding for a week and then wiping out intake to check for dirty oil. It was clean. Thank you DK customs.
-
Excellent 2 people found this helpfulA good quality well made kit. The kit should come with a grommet for the hole that is drilled.
-
Great product 1 people found this helpfulThis product is of great quality. The catch can is of extremely high quality and the kit was complete and very easy to install. Once I decided on how I wanted to route the kit and catch can, installation was around 90 minutes from start to finish. I highly recommend.

Easy worthwhile mod. 1 people found this helpfulThe kit with the billet catch can had everything necessary to install it. Now I actually feel like my throttle response is a little snappier and bike feels a tad stronger. DK service was excellent.
-
Catch can and external breather 2 people found this helpfulI so happy knowing that all that crap isn’t being sucked back into my engine. I never realized how much blow by some of my engines had until I went stage one. Stage 2 even worse. Install was easy and the kit provided everything, no unnecessary trips to hardware stores or auto stores. Service and staff were excellent. U won’t even know I’ve installed one. Can’t c it, get creative and you’ll be all giddy every time u look at your work. Ride safe everyone..enjoy every second of each ride.

High quality, competitively priced 1 people found this helpfulWorks great with their external breather system. I ordered some black spring clamps in lieu of the supplied hose clamps. The black clamps are less noticeable and were purchased from amazon.
-
Great, easy install 0 people found this helpfulEasy to install. I like buying a kit instead of having to piece the materials separately.

Just what I needed 0 people found this helpfulGood quality parts. Just what I needed to complete my external breather upgrade to my 2019 SGS.

Catch can system 0 people found this helpfulSo glad I found this product! I installed the breather system with no problems on my 2020 SGS. Took it for about a 100 mile ride soon after. When returned home I checked the catch can being curious. The can contained about two tea spoons of an oily water substance. Also the bike felt much stronger and no oil under my breather ! If you are considering installing this product GO FOR IT !! Well worth the $ !! Wish I had done this sooner ! I have now ordered one for my dad's 2017 SGS as well !! I spent good money upgrading to a stage II and having dyno work done glad I'm not building carbon on the pistons and killing my tune !! Thanks DK Custom Products!!!
-
A Must Have 0 people found this helpfulHarley should partner with DK customs and these catch can kits should come with every new bike purchased instead of running the tubes back into the air filter. Bike runs harder, cooler, and cleaner. Thank you
-
Catch can is top quality 0 people found this helpfulThis entire system is great! The install is straight forward and pretty simple but I am a career mechanic. I ordered the black catch can to match my motorcycle accessories and it's perfect. Best part of this is the engine still breathes but Not into the intake system.
-
Sounds healthier 0 people found this helpfulMuch better throttle response, gets back to the throttle much smoother. Much easier to maneuver at low speed. Even sounds healthier. Neighbor even said it sounded better when I came around the corner. Very happy.
-
A great product for the M8 0 people found this helpfulI bought the Catch Can and after 2000 mile I cleaned it out. I'll check it out next time after 500 miles. All the sludge that didn't go into the engine amazed me. I showed the harley tec a picture of what it got and he said that was his next project on his Road King.
-
Almost the perfect kit 0 people found this helpfulA quality product at a fair price. Excellent communication from DK and super fast international delivery. The kit is missing a couple of simple inclusions. I know where to mount the can is a very personal choice, but a 35 mm P clamp fits the can perfectly and should be included as part of the mounting hardware. Also a simple grommet to plug the standard air cleaner hole left by removing the snot pipe would also be easy to include. Overall a fantastic product.
-
Well machined parts that work 0 people found this helpfulGood stuff dose what it is supposed to do.

I'm a Viet Nam Vet; I work as a Program Manager for MHEP and VP of Latin American Rider's Association 0 people found this helpfulThis kit does exactly what it is advertised to do; excellent quality and craftsmanship. Outstanding follow-up and communication from DK in responding to any questions. I have a Screaming Eagle Air Cleaner and the modification was easy to figure out where I wanted to place my catch cam and route the hose. DK makes it simple to adjust whatever you ride to create a perfect fit. AND IT WORKS!

Top bit of kit 0 people found this helpfulNot the first time I’ve ordered off DK and this time was just as easy and quick. Really good quality and easy to fit
-
One little change 0 people found this helpfulI bought the M8 black catch can kit. The can itself is great, but I also went online after receiving the kit to search out a tee that was 1/4 - 1/4 - 3/8 to eliminate the need for the reducer going into the can. Everyone likes a clean look to the mods on their bikes and I think it would be a great upgrade to your kits in the future. No disrespect, just my opinion. I found the tee online in black plastic and stainless steel through soda companies as odd as that is.
-
Completed install was easy 0 people found this helpfulProduct was of good quality and install was easy. When I was doing the install I noticed the amount of oil that was being drawn into the throttle body. Not anymore!
-
high quality catch can. Super easy install. 0 people found this helpfulI ordered the wrong can on line. The next day I called and a very pleasant lady took care of me and stopped the shipment and changed the can for me, saving me the hassle of a return. The catch can is of high quality and the install was super easy. I spent an enjoyable afternoon working on my Road King. highly recommended.

Excellent 0 people found this helpfulSuper easy to install and eliminates the EPA induced misery of oil in the air cleaner. Taped mine up and painted the grooves black and polished the fins now it matches the jugs and looks great.

Fool proof 0 people found this helpfulNo need to fumble around the hardware store looking for parts and hoses. This kit is complete! If you can drill a hole through sheet metal, you qualify:-). Save your M8 from oil vapor sludge. Get this kit. The catch can is great quality, too!!

Great product 0 people found this helpfulDoes what it’s supposed to - keeps the hot oil mist from coating the intake. My bikes now seems to idle much better & runs well. I’d definitely recommend it.
-
Recently Installed 1 people found this helpfulReceived my kit today and installed it. Up to this point I really thought my decel popping was due to an overly rich mixture. As soon as I installed the can, poof all my poping was gone my idle sounds more stable and overall it just seems like the breathing was just instantly better. Great product easy install, exactly what I was looking for.

DK Custom 0 people found this helpfulThe first one I order got lost in the mail DK asked for a review a month later and I told them that I didn't receive it yet without hesitation they put another one in the mail . Put it on my 2018 Ultra bike run's smoother and inside of pipe is not so black, Highly recommend. GREAT SERVICE & GREAT PRODUCT !!! GOOD JOB DK Custom !!!!

Excellent product 0 people found this helpfulEasy to install and quality built. Only issue is the reducer could be a right angle, especially for the M*, so that the catch can can be placed right below the air cleaner.

EBS w/black powder coated catch can 0 people found this helpfulInstalled on my ‘17 SGS, utilizing stock air box with K&N filter since I rather like the look of stock. Got tired of oil fouling air filter & seeping out of casing, no matter where I had adjusted the oil levels. Now, no more oil bypass into intake; just fresh/clean air. I’m mechanically incline & always taken longer than recommended when doin’ maintenance since I’m particular & think of other ways than standard instructions. I opted to install a grommet in stock air box for the exit hose to pass through & route down just behind rear brake reservoir underneath foot pad & ziptied to aft mounting bracket of reservoir. Also have DK’s Thunder Torque Inserts within my gutted megaphone slip-ons. Combined with my crankcase vented dip-stick. All n’ all, excellent product & customer service.
-
Excellent Mod! 0 people found this helpfulInstalled with my OEM set-up. 30 minute super easy install. Looks good and functions as stated. I replaced the supplied plastic fittings with brass, but overall I would recommend for anyone who doesn't want hot oil fed back into their intake.
