How would a .........sound ?
#4
Well the A'PEXi cat-back has a b-pipe already..hence the name "cat-back" but I'd say that it's not loud at all...I basically have that setup right now, except I have the JWT intake (just as loud as the CAI). The cat-back keeps the car VERY quiet for having a fully modified exhaust. The intake is what's loud...and it's not loud until you really get on it.
