Cobra Sport are a family run business specialising in the manufacture of stainless steel exhausts and performance exhausts which are sold worldwide for many applications.
The heritage in the UK’s performance exhaust market spans over four decades with a proven track record of a commitment to continuous improvement and investment in new exhaust technology.
This commitment has resulted in the company being awarded the “Made In Sheffield” mark which is a symbol of excellence in manufacturing which is recognised worldwide.
Cobra Sport’s range of performance exhausts demonstrate the highest quality of manufacturing, each system is handmade in Sheffield and in-house expertise ensures that all Cobra Sport exhausts are engineered the highest tolerances ensuring a perfect first time fit, great performance and a truly pitch perfect exhaust sound.
Cobra Sport’s exhaust production facilities are geared up to producing performance exhausts in high volume, not only for themselves but also for clients such as Subaru UK, Isuzu UK and Ginetta Cars, to name a few. This does not preclude working for clients on an individual ‘one-off’ basis for prototype or custom developments whether that be for road, track or race exhausts.
Precision power, matched by sensational looks and an inspirational sound is the Cobra Sport promise.
This is the part of the exhaust system from the outlet of a turbocharger to the final vent to open air.
This is the part of the exhaust system from the outlet of a catalytic converter to the final vent to open air.
This is the part of the exhaust system from the outlet of a centre section to the final vent to open air.
This is the part of the exhaust system that is usually positioned at the rear of the exhaust and can be known as the “volume box” this allows the manufacturer to determine the final volume of the exhaust, usually the bigger the box the more silent the exhaust.
This is the smaller cylindrical box usually positioned towards the front/middle of the vehicle that removes the resonation sound that the engine produces, this box can be removed for a louder sound to the exhaust but can leave cabin drone a problem at motorway speeds for some people.
This is the final stage of the exhaust gasses before it reaches normal air conditions, size and style of this part has little effect on volume, sound or power. Style is the main focus.
One benefit of exhaust flex pipe is that it can reduce vibrations transmitted from the engine and exhaust into the chassis, which in turn can be felt by the occupants of the car. The flex pipe is used to connect rigid lengths of exhaust pipe, and the fact that it can flex and move reduces these undesirable vibrations.
All modern petrol car exhausts manufactured from 1993 are fitted with a catalytic converter and require one to enable the vehicle to be legal on the road. Cats contain precious metals and reduce harmful emissions of hydrocarbons, carbon monoxide and nitrogen oxides into the atmosphere. The catalytic converter works when it reaches its optimum working temperature, and converts the gases into water vapour and less harmful gases. The difference between a standard cat and sports cat is that sports cats allow more gasses to pass through, while still allowing the same emission results.
Removing a catalytic converter by fitting a de-cat pipe can slightly improve your vehicles performance compared to using a sports cat, however it is illegal to drive on the roads with a de-cat pipe fitted (designed for race/track use only).
This device helps to reduce carbon emissions. This monitors the percentage of oxygen present in exhaust gases and transmits information to the engine management system or electronic control unit (ECU).
