Location: Gloucester | On my 1.8 VVC i'm using the standard 4 bolt manifold, GTi MPi twin standard down pipe, De cat and a stainless piper middle box and back box.
I also have standard GTi cat back system aswell.
for info, all the 16v 4 bolt manifolds are the same for 1.4 1.6 1.8 and 1.8 VVC! So a standard GTi MPi has the same 4 bolt manifold as a 1.8VVC MGF or lotus elise VVC S1.
really early 16v Mpi 4 bolts manifolds from H to K reg are cast iron, 1993 they changed to tubular which flows slightly better.
Easiest option, is a Rover 16v 4 bolt manifold which is a easy find in a breakers yard, then a new GTi MPi twin down pipe off ebay which are a bargin £25 new posted! Then by a metro Cat back system. thats what ive done with my metro VVC. And I paid new double for my new gti twin downpipe they are so much cheaper now!!
