@Zstr28 It the thrasher kit from from Star Racing in Americus, Ga. All they do is make motorcycles go fast and they do it well check out their website, the owner George Bryce has been involved in motorcycle drag racing for a long time and has won a ton of races he is the man! They do all the work in house.
@@playaplaya9315 love them. My numbers torque and hp both are a tad higher than a stock 107 now. It also sounds a lot better. Albeit a lot louder so that could be a negative to some people. However I still just have slip ons so if you do a 2n1 exhaust it would really shine! I’m impressed with mine.
@@roadkingrider6532 thanks for the reply. Mine were ordered today. That’s great to hear. I have true dual thunder headers so we’ll see! Going on my ‘13 FLHTCU
