    Mk4 Exhaust manifold?

    Evening all

    Got a few questions

    I've got a mk4 astra 1.4 16v and I'm setting about trying to get a bit more poke out of it

    I read up somewhere that a manifold upgrade is good, and the best one to use is one off a 1.6 I believe as the cat isn't on the manifold, but is further down the pipe and should make it a fair bit more responsive.

    Does the manifold line up with the original studs on my 1.4? both on the block and the bottom of the manifold?

    hmmm probs best bet would be to look for a performance manifold made for your engine methinks.
    there should be plenty out there, i mean if i can get a performance manifold for a 1.2 8v corsa i'm sure they'll do it for a 1.4 16v astra
