Hello, been looking around for a 18" long oval casing with a 3" single inlet, and dual 3" outlet muffler for a 87 pontiac firebird. I feel like I've looked everywhere and I just can't find it. Anyone know if I can order a custom muffler from any online dealers, or where I can find this type of muffler?

Thanks.

They make two of them. mvr86s and mvv86s. Summit sells them. I have no experience with them though, just remember seeing it from browsing their site a day or two ago.

 

Awesome, thanks a lot man.
