Milltek Sport OPF/GPF Back Valved Rear Silencer Bypass Exhaust with GT-115 Brushed Titanium Tips for BMW M8 & M8 Competition 8 Series (F91 Coupe/F92 Cabrio) 4.4L V8 Twin Turbo | 2020-on | OPF/GPF Cars Only

Milltek filter-back valve-controlled rear section with GT-115 brushed titanium tailpipes for BMW M8 and M8 Competition F91 F92 2020 onwards

Give your twin-turbo 4.4 litre V8 the soundtrack it deserves with this premium filter-back rear section from Milltek. Engineered for petrol particulate filter cars, this valve-controlled rear silencer bypass transforms the character of the 8 Series M8 and M8 Competition while keeping cruising manners in check. The GT-115 brushed titanium tips finish the back end with a purposeful, motorsport-inspired look that suits the car perfectly.

Built and hand finished in the UK from aerospace-grade T304 stainless steel, the system uses mandrel-bent pipework for smooth, consistent flow and superb durability. The acoustic development focuses on a deeper, cleaner tone with no unwanted drone or cabin resonance. Open the valves for a richer, more aggressive note; close them for refined daily driving.
