Sports-Cat Versus Decat Components

Our SLN range also lists decat parts. Removing or defeating required emissions control equipment can make a vehicle unsuitable or unlawful for public-road use, including in the UK. Check road legality and the manufacturer's intended use before choosing any catalyst or GPF-related component. Decat products should not be assumed road legal.
