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 400CEL Catalytic and produce no Check Engine Lights, completely error free.\u003c\/span\u003e\u003c\/article\u003e\n\u003carticle data-scroll-scope=\"\" class=\"unreset\"\u003e\n\u003cp class=\"unreset\"\u003e \u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003ePatented O2 sensor technology design provides real-time data performance by accurately sensing every rotating displacement.
