Product Description

Valve

All Fi EXHAUST exhaust systems are equipped with valvetronic technology. 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.

Catless

The ultra-high flow catless downpipes remove restrictive factory catalytic convertor. They increase exhaust gas flow and performance gains, produce higher sound volume. And is usually recommended option going further with tuning. The downpipe is also equipped with a dummy oxygen sensor to reduce a change of the check engine light (CEL).

Sport 200Cell

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.

Ceramic Coating

Fi EXHAUST eliminates traditional thermal insulation materials that contain toxic substances, and directly coats the exhaust pipe with a nano-ceramic coating to protect from corrosion, reduce heat exposure to heat sensitive components in the engine bay and keeps temperature low. It’s a great way to improve longevity of the exhaust and other components prone to thermal degradation like wiring.
