Re: catalityc converter how much ? (P-Dub)
Sorry to take so long to get back to you guys.
The catalytic converter from Callaway has a three bolt flange at both ends, kind of like the test pipe for the MK1. I'm not sure if this is a direct bolt in replacement for 16V's, but it worked with my MK1 GTi when it was stock. Now that I have a 16V in there, I had to switch some things around, and I'm back to using the stock 16V cat. I wish I knew if this would fit or not, but I have only owned one car that came with a 16V from the factory, and that one has no cat now.
If you compare the two pieces; Callaway and TT side by side, you can see the difference in design. Callaway uses a fine mesh for the internals, while, if my my memory is correct, TT uses something similar to the factory design.
