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.
