By the way..... mustangs run like **** with offroad h-pipes in my humble experience. They hesitate off the line on low throttle and sound really chuggitty chuggity until you get the rpm's up.

Not so! My car passed just fine without cats. Just for giggles a friend of mines buddy and I threw my car on the tester. Emissions were just fine, that was with the stock motor though a few years ago.

So I guess it was my imagination, that when I put my cat h-pipe on that my car felt more sluggish down low? Hummm......my car runs a heck of a lot better with and off road h.
