I have a 94 gt and its all stock, want to get a pipe, took it to the shop today and they said the stock h pipe is what everyone else uses, he is just going to put mufflers on and the 2 back pipes that are about 2 feet long? is that what you guys are using? thanks

That description is perfectly true! A lot of systems on the 4.6 just sound refined and very deep, whereas the 5.0's just have that harsh, raspy sound. That's one reason I went with a 5.0 over a 4.6.
