AIRTEC Focus MK2 ST and RS De-Cat
 
Allows exhaust gases to flow much faster, More power!
 
Expect more popping & deeper aggressive exhaust sound. Gain 10bhp + (depends on spec of your car).
 
This part is sold for motorsport and off road use only and will NOT be able to pass a UK MOT emissions test or police road side checks.
 
This de-cat will not fit with the standard Focus RS exhaust system, an aftermarket system will be required.
