Cobra Sport Review

The latest offering from performance exhaust specialists, Cobra Sport, is this remote-controlled valved cat-back system for the sporty MINI Cooper S and JCW. With proven gains in power and torque, it’s the perfect addition to any MINI F56 – with the added bonus that the sound can be modulated from within the vehicle.

A new remote-controlled setup allows the driver to open the valve via the supplied key fob for a thrilling, aggressive sound on the open road, or to close it when cruising. With the valve open the sound is amplified with a deeper tone and more audible pops and bangs. On a 4,000 rpm track test, with the valve open, it measured 92.4dB (+13%) and 88.1dB (+8.5%) when closed.

Manufactured from high-quality T304 stainless steel and TIG-welded utilising 3in (76.2mm) mandrel-bent pipework, this cat-back system has been designed to deliver optimum gas flow – unleashing the potential of the Cooper S and JCW. Choose from either resonated or louder non-resonated format, with ceramic coated black and carbon fibre tips available as an option.

For those looking to take things further, the system may be ordered together with the new Cobra Sport high-flow sports cat or de-cat pipe (track use only). With further software and hardware upgrades, this full turbo-back system paves the way for significant power and torque gains.

With over 25 years in the performance exhaust industry, each Cobra Sport exhaust system is designed, manufactured and tested in Sheffield, the heart of the UK steel industry. Cobra Sport utilise TIG-welding techniques to ensure a flawless finish and quality that you can rely on.
