I have a guy that's buying my catback.

He asked what type of flange is on the beginning of the I-pipe where it meets the cat...I'm drawing a huge blank.

Help me out.

Thanks!

EDIT: It's a thirdgen exhaust in case anyone got confused.

 

On the SLP headers to the Cat, I used SLPs slip conecter pipe. Set up like this: Header I pipe-slip fit connecter-cat-exhaust. Check the SLP site.

I found it.
