Stone Exhaust Eddy Catalytic Downpipe BMW N20 F25 F26 (Inc. X3 20i xDrive, X4 20i xDrive, X3 28i xDrive & X4 28i xDrive)

Meet the latest patented technology that adheres to the world's increasingly stringent environmental regulations, at the same time enhances performance to another level on your BMW BMW N20 F25, F26, X3 20i xDrive, X4 20i xDrive, X3 28i xDrive & X4 28i xDrive. In comparison to commercially available linear frustums, the "eddy catalytic technology" adopts an arc-packaging method. The turbine emissions process produces a vortex effect which purifies the exhaust gases while maintaining an equal amount of back pressure. When compared to a variety of conventional straight downpipes, the patented eddy catalytic technology can effectively increase horsepower and torque. In the lower rpm you will be immerse with vast amount of torque until you reach higher rpm where the vortex effect really comes to life and opens up the Catalytic, resulting in a performance similar to a 100 CELL Catalytic. However in the lower rpm, the catalytic will produce efficient and clean emission similar to a 400C
