I have a 97gt with flowmasters and im going to custom make a catted h pipe. How would it sound if i bought a mac prochamber and welded in some high flow cats? Either that or i just buy a regular off road h pipe and weld some in.
Ya ya i know, thats why i was gunna weld some into an off road one. I want to buy an aftermarket catted h but i cant find one. I ordered a bbk catted h from 2 websites and both sent me and email saying that bbk discontinued it so ive just decided to make my own.
