I have an 02 GT Stick and have so far added the American Thunder Cat Back. I was wondering what brand would be the best fit for H pipes? I have stock headers and really dont plan on getting rid of them so i'm sure that'll have an effect on which to purchase. THanks
Flowtech off road fit perfect on my car before I went to full lengths , it was cheap too and still got 100 bucks for it when I sold it and the guy I sold it too said it fit perfect on his too ... just replace the studs in the manifold no matter what brand you go with ...
buy a stock H Pipe for your car, you can get them at ebay for 40-60 bucks, gut or remove the pre cats on them (first pair of cats) take of your stock pipe out of your car and store it DONT GET RID OF IT, put your new pipe in there, and enjoy!!
When ever you got to do your state inspection just pop your new pipe in there.
MAC has a new 3 piece H-pipe instead of the old 2 piece that required a clamp on the H Connecting Segment. The new one has the H section as a solid piece then a pipe that goes to the passenger side header and a pipe that goes to the driver side header. They have ball and cup fittings on all pieces just like stock, so It bolts right in without clamps or welding, mine fits perfect.
