Ok, im putting side exit exhaust on my car. i will be doing the exact same thing as the Mopar Xtreme lightweight. ill be putting the piece of sheet metal on the side to keeep the flames from burning it, and i am going to be producing a rear diffuser, for looks and also to keep the ass from dragging. It would most likely run from the top of the suspension back, blocking the 2 holes on top. Im not sure aobut the exhaust cutout options, seeing as how im making this so it makes my side exit not so strange looking. If anyone else is interested let me know, and if there is enough interest, ill start sooner, and maybe make a couple extra.
