The deal is, on the FWD V6, the front bank of cylinder's exhaust goes around the engine on the drivers side, and connects to the header for the rear cylinders. The exhaust leaves there and travels to the cat and the muffler before exiting.

If you want duals, you're gonna have to make some headers(I dont think anyone produces them) or split them up after the cat.

by going straight to the back like you want, you're lowering the exhaust to the ground, increasing your chance of scraping.
