Hey, New here and this is my first post, looking to get some info on my car and recommendations for upgrading it. So when I bought my '04 GT last year the previous owner said that it had a factory optional Stainless Steel exhaust with a more open up muffler and chrome tips. I know it's all Ford because the mufflers all say Ford on them. Is this a common thing on the 99-04 GT's? Doesn't keep me wanting to keep it all together but just curious. What I've like to do is put Long tube Headers, a short catted H-pipe and change out the mufflers but otherwise keep the Cat-Back section the same piping. Sound like a good plan for opening up the exhaust more? Any recommendations for parts?
