STONE Exhaust's Eddy Catalytic Downpipe utilizes their patented "eddy catalytic technology" which adopts an arc-packaging method. With its unique internal design, the downpipe produces a vortex effect which purifies the exhaust gases while maintaining an equal amount of back pressure. When compared to a variety of horsepower tests and straight downpipes, STONE's eddy catalytic technology can effectively increase horsepower and torque.
