Milltek Warranty

As long as you are the original purchaser, cat-back exhaust systems are covered by an anti-corrosion and manufacturing defect warranty and hi-flow sports catalysts and downpipes are covered by a 2 year or 80,000km warranty. Milltek DO NOT cover against any modifications made to their product after it has left the factory and also not for unusual use of the parts – for example, the use of Nitrous Oxide (NOS), aftermarket launch-control systems, damage caused by going over a speed bump too fast etc. Milltek warranties are offered on the understanding that the car’s power maybe increased by up to 33% from its original specification but exclude improper modification. Modifications made to increase the power beyond this will render the warranty void.

Please note: Milltek Sport hi-flow sports catalysts are manufactured from the highest quality materials and built with maximum performance and longevity in mind. However, they are designed to work specifically in conjunction with other Milltek Sport products and should not be used on their own (with the OEM exhaust system) or with other manufacturers exhaust systems. If the Milltek catalysts are fitted with non-Milltek exhaust systems, we are unable to provide any guarantee regarding noise quality, fit, performance or warranty against their operation
