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.
