Stock cats these days flow pretty well... very little power loss from them. You sure you need to swap it?

RE: who makes the best cat

I have a pre cat and another cat after that so I would think it is restrictive, plus Im pretty sure their cell count is probably more than 400. I know a new DP on my 02 TT really helped.

The best cats are on all the FWD 1.8t's. They flow extremely well when opened up to 3" inlet/outlet.

So replacing the 2 stock cats with just one high flowing one with stock piping wouldnt do any good?
