Finally finished mine up. The gentleman that I bought the manifolds from had ceramic coated them and had generally made them pretty. Really happy with the outcome.

did you buy or make the Y-pipe? what size inlet and outlet Y-pipe is that. I have the manifolds sitting on the bench while I am gathering parts so this was nice to see.

I had a local exhaust shop fab the y-pipe and attach it to the stock exhaust. I used 3fe exhaust flanges and the "stubs" to give the shop something to start with, and that diameter is in this thread (around two inches, I think). If you don't have the down pipes, you can still get them from RockAuto.
 
thanks. I have the stock pipes from rock auto but had no clue on the Y-pipe. I am guessing I will do the same and have the exhaust shop figure it out. Did you add an O2 sensor to the new pipes?

We've had a local shop make new exhaust on both a 2F and 3FE. For the 2F no O2 sensor is needed, but for the 3FE we needed new O2 sensor bungs installed. This was a simple task for the exhaust shop and the bungs were placed in location similar to the stock location.

Yep, no need for O2 sensors on the 2F.
