Press Release

We were keen to complete our exhaust range for the Subaru Impreza having built up an unrivalled reputation for manufacturing quality and performance with Subaru tuners within the UK and Worldwide. When the FE400 final edition model was announced we quickly sourced a vehicle to develop a group of exhaust systems to complete our expansive Subaru exhaust range which are now available in a number of configurations to cover all buyer needs and requirements.

Improving and unleashing the trademark Subaru boxer engine sounds was high on the priority list during development along with improving the gas flows. The decision was made to base our development for the final Subaru WRX STI on large bore 3"/76.2mm pipework (a significant increase over standard) for increased gas flow opening up the opportunities for power gains for our worldwide tuning partners.

Weight saving was also high on the priority list and we were able to save 4kg (15%) on the overall system weight for the non resonated turbo back exhaust with sports cat even with the much larger bore size of the Cobra Sport exhaust.

new Cobra Sport performance exhaust systems for the Subaru WRX STI offer the best of both worlds producing a deeper exhaust tone than standard which becomes highly aggressive and communicative when under full load completely overhauling the driving experience.

Cobra Sport's Sales Manager, Matt Thomas, explains "It's sad to see a final edition Subaru WRX STI having spent so many years developing and tuning these stunning vehicles. We're confident that we have done the WRX proud with our final product release for the Impreza range giving the car the trademark Cobra Sport sound upgrade to make the most of the unique raw sound of the boxer engine. The resonated turbo back exhaust with sports cat proved to be a popular upgrade during testing recording 97.1dB on the static 4,000 which is +16dB over the smaller bore standard exhaust system."
