Hi guys , im new to the forum.
I have a mk7 golf r and i am currently running a jb4 with a resonator delete, vwr600 intake , silicone hose and turbo inlet elbow from racingline.
I would like to get a downpipe next ,but im not sure as to which would be the best for not throwing any cel lights up.
Do you need a sports cat such as the bcs 200cell cat or can you just purchase a a downpipe without the cat.
Cheers for any help in advance.
