Get a local shop to do it. I am getting tru duals with a balance pipe with either flowmaster 40s, ravin 33s, or spintech promods, exiting infront of the rear wheels. It's gonna be 300 with the flowmasters or 270 for the ravin or spintechs. I'm having it bent up and over the frame rail, right behind the cab. Al 2.5" aluminized pipe, with 3" aluminized tipsI didn't want it near the fuel tank, so that was the best way to route it.
