I have a MK5 1.6 FSI and it currently has a cat back exhaust on at the moment, I've done a bit of research and noticed it has 2 cats. I have looked into a decat pipe for the secondary cat and cant manage to find anything for the 1.6 fsi engine if any one knows where I can get a pipe from that would be great or even the dimensions I need to be able to get one fabricated
