TTI into Rinehart DBX40s 0 people found this helpfulRachel was extremely helpful in discussing the best option for my exhaust. The long thread 118’s fit great, centered easily. Had to cut the thread stem down by 1/2 inch to reinstall. Sound was not affected. Awaiting weather to clear to go for a ride and see how much low end I have back. Very happy with the purchase and awesome customer service!

Excellent Product 0 people found this helpfulAfter great conversations with Rachel,(who is very good at her job as a customer service person!), I purchased these Thunder Torque Inserts for my Street Bob. I couldn't be happier! Rachel gave me great tips on how to install on my Cobra Neighbor Haters. The sound improved and the back firing has stopped. the bike seems happier. Great group of folks to deal with.

Excellent product 0 people found this helpfulI installed the long-threaded version after having first installing the shorter regular version. The shorter version didn't get the TTi quite centered (off by almost 1/2"), and I wondered about that affecting performance. I didn't feel they were working as promised. I worked with DK Products customer service, and they exchanged those for the ones with longer threads, and that helped get the TTI right in the center. Night and day difference! Deceleration pop is almost entirely gone. Very noticeable and significant increase in torque and power as measured by my Dyno-Ass. I have no doubt the results are real and would be proven on a Dyno test. (Moral of the story: TTI's deliver what DK Products promise especially when they're lined up correctly.) Great product!
