By removing the original restrictive catalytic converter located within the factory OEM downpipe, back pressure is hugely reduced, which in return means faster response, increased power and a more aggressive exhaust note.
Supplied with an adaptor to marry up to the original exhaust system, it also fits aftermarket systems, making it the a perfect solution to replace the OEM downpipe.
One of the only manufacturers that offer a cast elbow to retain diameter!
Features:
- Made from stainless steel
- AIRTEC laser cut plaque
- Smooth bends to ensure increased flow
- Fits original and aftermarket exhaust systems
- Improved performance further enhanced with remap
Please note: De-cats are sold for motorsport and off road use only and will not pass a UK MOT test or police road side checks.
