I love to think about exhaust. So, bare with me.
I for one, would like to see
this on a Kappa car. I was thinking a cutout before cat dumping out the fender would be ultra neat, but sure to be problematic and a huge effort. A full time system that wasn't too loud....like the SLR would be a pretty thing for sure if not practicle.
I admit that I am a side pipe fan. Whether it be a simple Nascar style side exit or a monster set of side pipes off an early big block Vette. But I wonder if enough people would want it. In the forums I visit, there are only a token few that go for it and that includes a Monte Carlo forum. It might just be because nobody offers a decent side setup? Clearance would sure be an issue. I have never looked close enough to be able to say if I think it would work or not. Even with space saving parts, clearance would be tight for sure.
