I have bought a second hand non res milltek cat-back, just wandered will the pipe going to the cats fit straight onto them or will I need a reducer? I don't see a part number for a reducer anywhere, and awesome Gti couldn't find one, but I have read in some place I think that a reducer might be needed, so a bit confused!
It's going on a 3rd 2.0t
