S5 TII swap - exhaust / downpipe question
Hey I'll be doing a swap soon and the one thing I'm missing as of now is the exhaust part. I want to keep the exhaust right now as cheap as I can and use as much of my n/a exhaust as I can. I did a lot of searching and didnt really find a straight answer to the following question, but I did read that the stock exhausts are the same from the y pipe back. So if I got a jdm downpipe, would that fit perfectly between my turbo and my y pipe?

The stock stuff is all 2.25" before the y-pipe, so it doesn't matter. The tubing that runs to each muffler is something like 1.75"-2", and I think it's the same for both NA and TII y-pipes. But the TII mufflers are a little better flowing than the NA versions. The downpipe is the only part you need to change for a turbo swap.

I've hooked up a 2.5 inch flange to a 3 inch flange before.
so if your stock is 2.25 and the down pipe is 2.5 it should be all that hard to get them to mate.
If not,just weld a 2.5 flange on where your 2.25 was.
Racing beat down pipes(TII) come in 2.5 and 3 inch.
