Down pipe and cat question
Posted: Wed Apr 22, 2015 6:29 pm
Hi all, I've just bought a second hand down pipe and cat and intended to modify it so that I could bolt in a straight through pipe but also replace the cat when needs be. The downpipe I've bought is different from the one I have, the one on the car has a lambda on the turbo manifold and then another one BEFORE the cat. The one I have bought has a lambda on the pre cat and then one after the cat... What have I bought??! Any help appreciated! Cheers John
