  • Total BMW Magazine - BMW M1 V8 with Cobra Sport Exhaust

    june-2013-bmwQuarry Motors is a highly respected BMW specialist in the Yorkshire region, they have been spending time on their latest project which is a BMW 1 Series Coupe with the V8 engine from the BMW M3 E92. I'm sure this modified 1 series would make the actual M1 go and cry in a corner in a race.

    Ashley from Quarry Motors approached Cobra Sport to create an exhaust that would increase power and deliver a sound that would make the windows shake, but at the same time not want to attract unnecessary attention from the police. Yes that is a hard task to overcome...

    After discussing many options with Ashley everyone decided on dual independent exhaust systems, with a switch in the cockpit that can be pressed to allow the running of a loud or quiet system depending on what the mood takes you.

    Needless to say the 'best-of-both-worlds' project was completed and featured in the Total BMW magazine.

  • Japanese Performance Magazine - Toyota GT86 Feature

    Full feature in this well known magazine describing the development process behind this new system.

    "Prior to developing the new exhaust Cobra Sports engineers analysed the OE exhaust together with an initial power test run , to determine where improvements could be made to enhance the personality of the car . After thorough testing , it was identified that the first improvement would be to increase the bore size of the system by 18% from the vehicle manufacturer's original specification of 53.8mm.

    Fabricating the exhaust involved mandrel bending the stainless steel tubes to ensure a superior finish. Independent testing has proved that Cora Sport GT86 primary cat back system,working in conjunction with the AEM induction kit, reduces back pressure allowing the car to breathe more efficiently and boosts performance from an initial 196.5 bhp to a genuine 207.5 bhp, whilst also benefiting from a 27% reduction in weight when compared to the OE exhaust."

As with any Cobra Sport exhaust a great sound comes as standard, the unbelievable resonated sound of the Cobra system is pitch perfect. Behind the wheel, under load, part throttle or idle the volume on the Cobra Sport exhaust system is only marginally higher than a standard exhaust but comes with a unique and improved base sound, on full load the Cobra system really comes to life!
