TT RS

The 100mm into 90mm downpipe, coupled to the Powervalve 100 cell 125mm oversized  catalytic converter complete with secondary cat delete pipes for the Audi TTRS (8S) 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).

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.
