for the last couple months i've liked the sound of my race bullets and my upr x-pipe. however, i'm left wanting more of a muscle car sound rather than the exotic tone i have now. anyways, how do prochambers generally sound with straight thru mufflers? i know people usually go chambered with h-pipes and such, but the prochamber is different and i don't want to change out my mufflers. and are there any good off road h's out there, i've heard fitment and quality on the mac one's were iffy and bbk midpipe's don't always sound the best.
