I have a 2002 GT auto got about 150k miles
bone stock but on the way KnN intake kit.
i have either a crack in my exhaust manifold or a leak in the cats not sure but either way i wantd to swap these anyway.
What's best for sound quality , i heard the h pipe is a much better sound but less loud than the x, ad should i got with cat backs or un catted? not so much of a braniac when it comes to this.
also what are the best headers to go with shorties or LT's, i was thinking about BBK shorties.
Thanks to whoever gets back to me
Nick,
