I'm not sure if I want (the noise)to get a slip-on anymore.I am sold on the PC3. What type of HP gains can I expect from a PC3 withthe stock exhaust on a 2007 cbr1000rr?

 

I'm not sure about the 1000RR's, but on the 600RR's, right around the 4k mark, there's a massive torque drop, and if you are slow on the throttle, you can REALLY feel it and gets annoying quick. The PC3 gets rid of this completely, as well as smooths out the entire power band for a smoother acceleration, and better throttle response, but I'm not sure about actual true HP gains from the PC3 alone.

 

same with the 1000rr
there is a massive torque drop right at 2500

flapper mod and gearing change helps a little but the only way to realy fix it is with a custom map regarldess of what pipe is on it
