Exhaust help!!

Hi can anybody help me , are all big block manifolds the same i.e does a gti one fit on a carb engine and vice versa as im after a stainless manifold for a 1988 1.8 carbd engine
Thanks

fitment wise to head yes 1.5-1.8 8v are all the same. the exhausts can differ in diameter plus you got the nice gti 6 bolt flange 6-2-1 system and the toilet bowl style.

personally id rather have an oem gti 6 bolt type than pattern 4 branch. they flow really well so will do you fine unless you have poured serious money into upgrades
