You will need to modify the pipe from the cat to the manifold to extend as well. I had this done on my car as well, but that should be pretty much it. You have the rest covered with the O2 sensors

So it goes Manifold ---> Downpipe ---> Cat ---> Cat Back exhaust.

I thought the Y8 manifold came with the downpipe and cat, so really all you would have to cusomize is the attachment from the catalytic converter to the existing exhaust piping.

What you're saying here sound slike there's a custom connection between the manifold (header) and cat???

I always thought they were one piece. Interesting.

the Y8 has a downpipe, but not cat. I had to get an aftermarket cat and they custom fitted to make it work.

brian is a pro at this conversion but now that he has it all fixed, he goes for the twin cam conversion. i can see the evil grin on his face! brian...what are you doing with the old engine/tranny? i have been looking for donations

Hehehe, you got me so on the nose dude, as I was reading your post, huge grin on my face. The LSD Tranny and clutch are sold to Jeff, I have someone interested in buying my engine so far, it's posted on the board, have to pay for my swap somehow. If this deal falls through, we can talk

LEITNER

we can talk anyways Dr.Evilgrin!

Ya know I love ya bro!

since you're getting the swap, wanna sell me your Y8 exhaust manifold conversion? I would really just need the exhaust manifold, downpipe, and modified cat. PM and we can work it out.

Sorry, Manifold and downpipe is being sold with the engine, Cat as far as I know is being used with the swap.
