X and Y Pipe Exhaust Kits

Doug's X-pipe and Y-pipe kits help to balance exhaust pressure resulting in increased low R.P.M. power. Our specific fit kits include all the necessary parts and pieces to connect Doug's headers to the factory or aftermarket catalytic converter. Universal kits include 4- 45° bends and one cross-over pipe. Specific fit kits are made from aluminized tubing (A787) for superior corrosion resistance.
