I currently have a SI/DO exhaust no cats with the exit in front of the rear tire. I need to change it because I bought a body kit and the exhaust exit interferes with the body kit. Later I would like to install an eaton blower. The question is wich way should I go?
1.true duals with 2.25" tubing
2.true duals with 2.5" tubing
3.single exit with 2.5" tubing
4.single exit with 3" tubing
I am looking for performance I don't really care much about sound. Remember I do not have any of the cats. I don't really know if the cats issue affects the tubing diameter but i think that is an important fact.
I will greatly appreciate your input.

i just know when i took my cats off my truck lost power. and if your going to run new mufflers for power you would wanna do a straight through magnaflow or bassani or borla or something
I was thinking about this muffler maganaflow 12568 that has the x pipe inside. Even though the muffler is 2.5" in and out I was thinking to continue the 2.5" tubing to the inlet and at the exit install 2.25" tubing for now and when I install the supercharger i could change that 2.25" tubing to 2.5" for better flow. It is a good idea?
