The first exhaust I had was a side exit under the rear quarter panel and stock programing. It still would turn my old cudy cabin a black/grey on long road trips. I honestly think the only way is to get it as far back and as low as possible, I just don't know how to do it and still be ascetically pleasing with out doing a temp "towing" exhaust.

currently running a smarty. It can be pretty dirty if I run it on kill, and can't remember the last time I had it loaded with a crazy heavy fueling tune. I'm wanting to get a the UDC dongle, but don't know to much about it since I have fell out of the "mod your truck crowd" guess getting older you get more boring. I've also ran superchips, edge juice w/attitude and edge EZ in the past.
