Milltek 80mm OPF/GPF Back Exhaust | BMW G8X M3 M4 - Brushed Titanium Tips

Description

The Milltek 80mm Cat Back OPF/GPF Back Exhaust System with Centre Resonator Bypass is engineered specifically for BMW G8X M3 and M4 models (S58 engine). This direct factory fitment system replaces the factory OPF/GPF unit and connects to the OEM rear silencer, requiring no modification to existing components. Constructed from T304L stainless steel with mandrel-bent tubing and CNC-formed junctions, this system features a 3.15" (80mm) primary bore. The non-resonated design eliminates the centre resonator for a more direct exhaust path and engineered tone character across the rev range. GT-115 brushed titanium trim options available. Hand-finished construction meets Milltek's standard for precision fitment and durability.
