Ive got a 91 STD hatch with the shitty hf style manifold. I just picked up a z6 swap with the header and downpipe. Will this be a bolt on process..like is it long enough to reach the cat, or is it to short or does it just bolt right on. Anyone done this or kno how i can put it on.

 

uhm...ok..nvm..i dont have the std manifold? lol

 

ok, for some reason i have a 4-1 manifold and b-pipe. The runners on the mani look bigger than the ones on the z6 mani..but the z6 is a 4-2-1 setup. Think its worth the trouble of putting that on. Would there be any noticable gain?
