The latest hot new product to drop from Sheffield-based exhaust specialists, Cobra Sport, is this high-quality, cosmetic, quad tailpipe system for the popular BMW 420i M-Sport Coupe, Cabriolet and Gran Coupe.

Manufactured from high-quality T304 stainless steel, this centre and rear section exhaust upgrade features 2.5in (63.5mm) mandrel-bent pipework with aggressive slash-cut quad tailpipes. Designed as a direct replacement for the OEM system, it fits both Coupe and Cabriolet M-Sport models, once the mandatory aftermarket replacement rear valance has been fitted.

This M4-inspired conversion would make the perfect addition to any 420i M-Sport, especially remapped examples, which are capable of impressive power and torque gains.

Like all Cobra Sport exhausts, this system utilises precision TIG-welding techniques for exemplary fit and finish - a feature that sets Cobra Sport apart from other manufacturers.

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.
