Press Release
Keen to make a step above and differentiate from the competition, Cobra Sport have used their extensive experience and use of new exhaust technology to create a product which truly stands out in the aftermarket performance market.
The Cobra Sport research and development team quickly made the decision to base the new M3 exhaust systems on 3" (76.2mm) T304 grade stainless steel pipework. The larger diameter 3" pipework enhances the capabilities of the 3.0 litre twin turbo straight-6 engine and utilising advanced gas flow design, allows for substantial performance improvements. The M3 development has been based around a valved cat back exhaust with the addition of a secondary de-cat (catalyst bypass) exhaust upgrade. The cat back exhaust includes a centre H-Pipe section, designed to mix and perfectly balance gas flow from both sides of the engine to increase power, improve flow efficiency and enhance the exhaust tone.
Extensive road testing was undertaken in order to ensure there was no resonance or exhaust drone in the cabin throughout the rev range in all drive modes. The sound of the new Cobra Sport exhaust boast vastly improved tonal characteristics, with the new exhaust offering a deeper more aggressive sound when under full load. The Cobra Sport exhaust incorporates a pair of exhaust valves designed to utilise the existing valve motors , enabling continued use of the M3 drive modes to adjust the dynamic of the exhaust. In the comfort driving mode the valves remain shut forcing the gas flow through the flow optimised rear box, creating a finely tuned exhaust note for a sporty but unobtrusive sound track for everyday use. With the valves open in Sport and Sport+ mode, the gas flows through all 4 tips creating a highly aggressive sound track.
Cobra Sport Sales Manager Matt Thomas commented, "Building on an existing first class reputation in the BMW tuning market, we're excited to be adding the Cobra Sport sound and performance upgrade to the stunning M3. Power testing the secondary de-cat and cat back system revealed an impressive +21.25bhp and +9.2lb-ft of torque. The free flowing 3" pipework and optimised exhaust technology opens up huge potential for M3 owners looking to increase power whilst also obtaining a pitch perfect exhaust tone."
Cobra Sport have improved the styling of the BMW M3, creating a noticeably enhanced and balanced look to the rear of the M3 with a choice of quad 3.5in (88.9mm) inward rolled baffled or inverted highly polished stainless steel tailpipes. For those looking to take the style upgrade a stage further, upgraded ceramic coated matt black 'Blackout' tailpipes are available.
