Using our state of the art facility we brought to you one of the best pipes on the market for the AXYS.... but why stop there? We set out to make the best manifold on the market also! This y-pipe boasts a 3-4 horsepower gain over the factory manifold when used with our pipe. 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 only, not intended to be used with the stock single pipe. When using this y-pipe with our pipe you must run our custom tuning loaded via the Bully Dog GT or detonation will occur. Ceramic coated to keep heat in the pipe and reduce under hood temps. Gaskets not included.
