The Powervalve 76mm 100 cell oversized  catalytic converter has a gas flow ratio greater than any other product on the market, and having a 40grm wash coat which is up to 8 times greater than cheaper cats offered can, therefore, handle up to 10 years of hard life (...this is where the true value of the cat lies - in the precious metal content).

In addition to the power increase, you will experience a major uplift in the exhaust note precluding the necessity to replace the OEM exhaust system.

Due to the huge increase in gas flow we recommend that the car is mapped to stage II in order to maximize the power potential of your car.

Fitting this pipe without the remap will cause the CEL to illuminate.

Whilst we do offer a cat delete pipe you should note before purchasing that it is illegal to run your vehicle on a public road without a road legal catalyst installed. With this in mind, you should only consider a cat delete for closed road and/or track use.
