Just installed my HMF pipe , wow what a difference from stock, really noticeable from low to mid RPM. Not overly loud until you romp on it. Nice low rumble at idle. How much of a diffrence will a power up kit make ?
The best thing to do is get a pipe(which you've done)take the airbox lid off, get K&N w/ adapter, put outwears on, and then re-jet.
