thought anything over 2.5" wouldnt see much gains
saying that, I was told this with K03 and K03s so dont know re bigger turbos
?? Gains over what?? As my system is pretty much a stainless standard system
Says turbo back exhaust in your sig, from that I would have thought you have at least a 2.5" stainless system from Milltek or other brand.
so I thought anything over a 2.5" system you wouldnt get any additional gains
