I think I've read that they're actually a 2.5" outlet? I do remember mine was too small for the catback and a muffler shop couldn't expand it so he just welded it on. At the time the car was pretty much stock and I didn't think twice about it but now with the mods I've done, I'm starting to question myself and if I should fix it....although I'd like to go with true duals when I can afford it.

It's meant to plug straight into the stock mid pipe which is 2.75" OD.

Ouch, guess that's gonna hurt me then. Now I have a 2.5 inch bottleneck. Thanks for the quick replies.

Might actually pickup a few more ponies when this is fixed

This y pipe drives me nuts personally. Had a section off the other day and now the whole system rattles again, 3rd time Im going to have to take it to get adjusted . Drivers side is hitting the subframe and now the I pipe is hitting the trans tunnel, and its 2.5"? lol

Might want to get it tack welded in a couple spots. I'm not thrilled with the way my TSP catted Y fits on the drivers side. It's a bit too low for my taste. At some point I might swap to their new catted Y. Hopefully it fits better.
