Hi guys, i had used the search button but havent found the right anwser. I have a dynomax catback with the stock H pipe right now, i may have the possibility to put a hand on a used magnaflow hi flow cats x pipe next summer. My question is, beside the sound and the little weight reduction over the stock h .... What kind of power improvement we do get from an aftermarket X-pipe on the terminator?
Tx guys.
