Default exhaust question
I have a stock 98 with TI by-pass mod exhaust from the axle back. Thinking about an X-pipe. What size are the stock pipes(ID/OD) between the cats and where the TI bolts up?

Im not sure but Im pretty sure that most companies that sell the x-pipe are going to have the 2.5 in pipe.
If I can find a tape measure Ill go check for you real quick.

FYI: Borla, Corsa, Bassani, Magnaflow, and WCC all sell a C5 X-pipe.

Default x pipe
Has anyone on here had any experience with a X-pipe of this type? It is a 2 1/2" stainless, a local guy has one for sale

I love the TI mod, very quite at cruise 70-80 mph but loud when I get on it which is what I was going for. It could be a little louder when I get on it, should have drilled the holes a little bigger, I think it would still be as quite as it is now at cruise but better at WOT.
