Cobra Sport De-Cat Pipes are designed with performance in mind, replacing the catalytic converter with straight pipework. They are built to the highest quality and have undergone extensive testing and development so that they not only look great, but also improve sound and performance.

• Enhanced performance with noticeable power gains
• Improved sound with a sporty tone
• Precision engineered for a direct fit

This de-cat pipe replaces the primary catalytic converter in your car's exhaust to improve sound and performance. The catalytic converter is the most restrictive part of an exhaust system, reducing gas flow. De-cat pipes which remove the cat entirely will provide greater power gains, but will not pass any emissions tests.

Replacing stock pipework with wider, especially designed Cobra Sport pipework allows better performance from your car's engine. This is achieved by allowing a faster flow of exhaust gasses, reducing the limit of how quickly the engine can take air in.

All stainless steel Cobra Sport Cat-Back & GPF/PPF-Back exhausts and solid pipe sections are supplied with a lifetime anti-corrosion warranty*. Cobra Sport downpipes and parts containing a sports cat or flexible section are supplied with a 2-year/80,000Km warranty* on defects only. All relevant fittings and gaskets are supplied with this part.
