I wanna remove the cat on my car so that the induction kit and exhaust have a bit more effect on power. Online autosport do a cat replacement for ?53 but you need to buy a 4 branch manifold to fit this. Is it worth paying ?109 for the manifold aswell or should i look for a direct replacement? will it be a better increase with a 4 branch manifold? Does anyone know anywhere else i can get one? Can i get my dad who is a welder/fabricator to make me up a pipe to fit in its place? also how much will a garage charge me to fit a new manifold cos it looks like a pain in the arse to fit!
