This technology is not only used to control sound volume, but also enhance overall performance of the vehicle. Before the inception of this technology, horsepower and torque were irreconcilable contradictions in the design of exhaust systems. This allowed sports cars to have high torque power at low rev speeds and even higher horsepower capability at high rev speeds.\u003c\/p\u003e\n\u003ch3 style=\"font-weight: 500;\"\u003eCatless Standard Version\u003c\/h3\u003e\n\u003cp\u003eThe ultra-high flow catless downpipes remove restrictive factory catalytic convertor.

The downpipe is also equipped with a dummy oxygen sensor to reduce a chance of the check engine light (CEL) being triggered.\u003c\/p\u003e\n\u003ch3 style=\"font-weight: 500;\"\u003eRace 100Cell\u003c\/h3\u003e\n\u003cp\u003eThis kind of catalyst is generally used in race cars , so it is often called “racing catalyst”. With the larger cells and fast exhaust flow rate, it is smooth, durable and do not have refractory wool burn-out problems. The higher the number of the cells, the smaller and denser the hole is. The higher the back pressure, the more it can enhance torque performance, while the opposite is true for increasing horsepower.Converting your stock catalyst converter (400~800 CPSI) into our metallic catalyst converters will result in significant enhancements in airflow discharge that circumvents the limitations and parameters set by car manufacturers.\u003c\/p\u003e\n\u003ch3 style=\"font-weight: 500;\"\u003eSport 200Cell\u003c\/h3\u003e\n\u003cp\u003eWith the larger cells and fast exhaust flow rate, it is smooth, durable and do not have refractory wool burn-out problems.
