Let's start over......
The Borla Pro XS looks like the ROR muffler to me. I am looking at possibly modifying the OBX Y which is 2.5" in and out into a 2.5" into a 3" out and into a single 3" Pro XS muffler then side exit before the tire to the Saleen tip. Thing is the Pro XS 3" si/so only comes in a 14"x9-1/2"x4" body center/offset in/out.
I commented in the 5.0 true dual thread...
Almost exactly what your looking for buddy - but true dualed
