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.

Look, sound and quality you can trust

The GT-115 burnt titanium tips transform the rear of the G82 with a high-end, heat-treated blue titanium finish and a larger, more purposeful outlet. The tone is deeper and more engaging than stock, with Milltek’s trademark refinement for daily driving. We have installed this system on customer cars and the feedback has been overwhelmingly positive for both sound and finish.
