Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

 This product alters a factory emissions control device and does not meet current emission laws. For motorsport use only.

The part is used to bypass the catalyst from the exhaust to create a ‘Decat’ or Sports Cat system. Eliminating the catalyst will greatly enhance the gas-flow and the performance, adding significant Hp to your vehicle by removing the density of the catalyst in which exhaust gases are pushed through.

All our performance exhaust systems are designed with you in mind, and we cater to an ever-expanding range of vehicles. We believe in continuous evolution, and our research & development team work throughout the year to deliver the most in demand solutions to all your performance exhaust requirements. All of our products are made in the UK and distributed to more than 90 countries worldwide, making Milltek Sport one of the most accessible performance aftermarket brands on the market.
