I am thinking of going with a Screaming Eagle high flow air filter and the Cobra Tuner, leaving stock pipes which are pretty loud as-is. My goal is to increase the bike's torque. If it doesn't work I suppose I'd have to go with increased exhaust pipes - maybe Screaming Eagle? Any suggestions on this set-up?

 

Very happy with my FP 3, works as advertised !

 

The OP never said what bike he has or if he plans on going past stage 1. But for me, the FP3 has been perfect and I could not ask for more. swifty
