exhaust for a 1100

Hi there my 1100 golf is cuming up to that time where the mot is about to run out and will need a new exhaust and possibly the manifold. so i thought about putting a performance one cos the price of a standard one is stupid, but i canot find one, the only one that i can find is for a mk1 polo (ashley), will it fit and where could i find one from. Cheers Phil
