External blowby system Review by Ronnie
Excellent system to capture blowby from going back into carburetor & capture oil in catch can instead. High quality product from DK custom products. Thanks for great customer service. (Posted on 11/19/2020)

Great Design Review by Mark
Another great product. Using with stock AC but this is really helpful keeping that hot oil / air out of the engine. I have cleaned it once after a 1000 miles and although not a ton of oil came out, enough to make me glad I have this product. I'm sure the engine appreciates it. :) (Posted on 9/14/2020)

Very well made product Review by Dave
I called and ordered a custom unit for my bike. I already had some of the required pieces. They helped me with a custom kit. Excellent customer service wish more companies were as good as they are! A real pleasure doing business with them... (Posted on 9/1/2020)

Great product Review by Aussie Bob
Bought this to see how much blowby as my106 S&S stroker uses 1.5qts oil per 2500 miles.
Little blowby but will be great for the new pistons.and rings as only fuel and air will be going in.
I have bought other products from DK. They are great to deal with.
Highly recommend.

Awesome Product Review by Lee
I like this containment can. I can help the EPA do a better job by disposing the billet can contents with my old oil that I take to the auto parts store for disposal. It makes more sense to use the breather can vs. running harmful waste back thru the engine. DK Custom Products has a lot of cool stuff to add to my bike over time. (Posted on 6/4/2020)

Perfect! Review by Corey A.
The DK Custom 4 Stage can does exactly as claimed. It totally keeps that nasty oil off the bike. Perfect design! (Posted on 5/28/2020)

4stage catch can Review by 03SportyBoy
Another DK awesome product. Tried other catch cans. They still "misted" oil all over my chrome. This 4stage catch can completely eliminated that. Best $50 I've spent towards my bike! (Posted on 5/28/2020)

Stopped the oil mist from the breather bolts with the DK catch can system.

Added some rubber O-rings into the grooves to give a nice look. (Posted on 1/16/2020)

Looks great Review by Alan
Replaced my air cleaner on a 1998 Dyna Wideglide and decided not to vent the oil from the head breather bolts back into the engine. This catch can allows the oil to be captured and emptied occasionally when needed and it looks great! I purchased the cnc machined aluminum version. (Posted on 3/20/2019)
