Hi, I have a basically stock 92 Mustang GT, it has equal length shorty headers and bassani x-pipe w/cats, bolted to mac mufflers. My question is if I cut the x-haust pipe just before the mufflers and get rid of them, the x-pipe will have about 2-3 ft of straight pipe still bolted to it and that will be my whole x-huast. Will this hurt my cars performance any, do i need the back pressure that the mufflers produce for my valve train to work properly? I am mainly doing this for the sound, and this is a daily driver. Someone please HELP! Thanks alot!
