THRASHIN Anti-Reversion Dual Exhaust System - M8 Softail
We designed and built this dual system with Feuling Parts over 4 years ago, and the time has come to offer it to you!
See the dyno graph below where we started with a stock 107" putting out 77HP and 100TQ. We upgraded the cubic inch to 114", installed Feuling 465 Grind Cam, Feuling Oiling System, Beehive Valve Springs, K&N Intake, and our Thrashin Dual System and put out 113HP and 131TQ.
Hand crafted out of stainless steel right here in Los Angeles, CA!
