I have a bunch of different ideas for exhaust on my pony, and I dont know what to go with. I'm puttin alot of thought into it cuz I want it sound right the first time. Alot of ppl say that straight pipes dont sound good, but i found a youtube video of a sixer with straights and it sounded good Turbo 4.0 V6 Mustang CATless twin 2.5 pipes, no mufflers. I dont know how much a turbo would affect the sound at idle. I think it sounds sweet on this pony.
