Good to see you're doing more to your car. Got sick of CIS, eh?

Sounds like you have a plan already. But in case you're interested, or in case anyone else is, here's a pic of my engine with a Borla right-exit muffler, 3 in and out, and a "faux" 3 in outlet on the wastegate dump pipe on the left side. This is a Bob Holcombe design, and is mated to a Garrett turbo (built by Kevin). One interesting thing is that with this arrangment, there is no Marmon clamp or bolt-on flange. There's a stainless ring on the end of the muffler inlet that engages with the turbine housing. It's a slip fit right into the turbo. The only thing holding the muffler on is the big band clamp you see. It's amazingly secure and very easy to take on and off.


Here's the ring on the muffler:
