Frequently Asked Questions

How are your exhausts made?
All of our exhausts are made from aircraft grade 304 stainless steel and constructed using precision TIG welding with mandrel formed bends in the pipework for a smoother gas flow. We pride ourselves in producing high quality products.


What sound can I expect from your exhausts?
Our exhausts will have a more sporty tone than original equipment exhausts. This is an inevitable result of the less restrictive systems we produce. However, with careful design and production methods, we aim to keep a subtle sporty tone.
Of course if you prefer a loud system, then one of our non-resonated (no centre box) exhaust systems will provide a louder exhaust note.
Many of our products feature a movie of the exhaust and give some idea as to the sound which you can expect.


What power gains can I expect to achieve?
Of course this varies from engine to engine, our systems are designed and manufactured to optimise gas flow with increased diameter pipework, free flowing silencers and mandrel bends which provide a much less restrictive exhaust system than original equipment exhausts, resulting in a much better engine response and increased BHP. Typically you can expect to achieve around a 10% increase from the installation of a cat-back system. Some individual products also show approximate power gains.

Do I have to modify my car to fit a Cobra Sport exhaust?
No, our exhausts are designed to be exact replacements for original equipment exhausts and we provide a fitting kit so you will have everything necessary to fit one of our systems to your car. Some exhausts may require the use of alternative rear valances, please contact us for further information

Is it legal to put a de-cat pipe on my car?
You can only de-cat your car if it was registered prior to 1992, otherwise it will fail the emissions check at your MOT station.

What is the difference between resonated and non-resonated?   

Resonators are box chambers incorporated into the exhaust system, which are used to make the exhaust quieter, by cancelling certain sound frequencies. A non-resonated exhaust system will therefore, give a louder exhaust note and a resonated exhaust system, a quieter exhaust note. Either option will still provide extra performance.

What is a Slash-Cut tailpipe?

Slash-cut tailpipes are finished and cut off at a 15 degree angle, and suit certain types of vehicles depending upon the shape of the bumper and overall aesthetics of the vehicle. If you require any advice on which tailpipe would be most appropriate for your car, please give us a call.

How quickly will I receive my exhaust?
We aim to deliver within 3-5 working days of you placing your order. However, please allow at least 2 weeks from placing your order to arranging any professional fitting appointments, this is in case there are any courier problems, or technical queries which we may need to resolve for you.

What about fitting?
We always recommend that you have your exhaust fitted professionally for both health and safety reasons and to ensure the perfect fit. There are many garages able to provide this service and we are happy to make recommendations in your local area. We also offer a fitting service at our factory workshops by appointment, please contact us for details.

Will my exhaust require any maintenance?
Mounts and rubbers should be checked annually and may need replacing from time to time over the life of your exhaust. Provided these items are checked and maintained, your exhaust will provide many years of trouble free motoring.

How do I keep my exhaust looking like new?
If you do not clean your exhaust, it will eventually become discoloured and be more difficult to bring back to its original finish. Regular cleaning with a non-abrasive metal polish such as Solvol Autosol will ensure that your exhaust continues to look as new.

What warranty or guarantee do you provide?
Our lifetime guarantee and anti-corrosion warranty covers manufacturing and material defects for the original purchaser. Provided that any claims are a result of normal usage and the car has not undergone any excessive engine modifications. Our sport catalytic converters have a 1 year warranty on defects only. As we deal directly with consumers ourselves our after-sales support is of the highest importance and enables us to take a flexible approach considering each case individually.
