Using our state of the art facility BMP brought you one of the best pipes on the market for the Patriot 850.... but why would we stop there? We also set out to make the best manifold on the market! The BMP y-pipe boasts a 3-4 horsepower gain over the factory manifold. This manifold broadens the powerband and adds a few ft/lbs of torque, making this a modification you really feel. Developed and tested with our pipe or a stock pipe. This Manifold can be run with no ECU tuning or for best performance to get our tune via Torque Link or Hard Flash. Ceramic coated to keep heat in the pipe and reduce underhood temps. Gaskets not included.
