Quill EVO2 Exhaust system
 

Hi all just bought an 09 XTX, well pleased with it. It came with Quill evo2 exhaust system which sounds & looks great. The only thing is it pops and bangs on the overrun, which is great for scaring old ladies and small children, but is beginning to get on my nerves a little. It has a K&n stage 1 filter and a Nitro x power commander thing(which having done some research seems as useful as an ashtray). Would a true power commander cure the problem or do you have any other advice?

Block off your AIS & the poping will stop.
