With a stock SE exhaust, you need to use a dual-outlet muffler. Don't go back any farther. It'll take some custom work, as the exhaust is routed differently on the SSE and SSEi.

he'* right....that'* what i had to do to mine.

Anyone know how my SE exhaust is routed compared to an SSEi? I have the dual outlet factory exhaust. The muffler dumps on either side like an SSEi muffler (which I suspect it is). Remember that I have the L67 original engine--not a transplant.

The SSE and SSEi routed the main feed downt he center of the car....I THINK the SE is routed down the passenger side to a smaller muffler on the passenger side under the trunk well. If you have the big monster muffler mounted transversely under the trunk, you have ours, and that'* what I'd expect.

Yeah, thats what I have. I haven't compared my SE to any other SE so I wasn't sure if there was a difference. BTW, that muffler is a beast! I bet we could shave some weight by going with an aftermarket.

A beast it is. I had to drop the back end of my exhaust when Josh and I installed my receiver hitch last month. It wasn't pretty.....other than pretty heavy.
