Milltek Axle-Back Exhaust System for BMW 3 Series G80 M3 & M3 Competition (2020+) OPF/GPF Only | ECE Approved | GT-115 Cerakote Black Tips | SSXBM1170

BMW G80 M3 rear exhaust upgrade with stealth black ceramic tailpipes - SSXBM1170

Transform the soundtrack and rear-end presence of your S58-powered saloon with this premium rear section from Milltek Sport, part number SSXBM1170. Designed for petrol particulate filter equipped models, this EU type approved system brings a deeper, richer tone under throttle while remaining civil on the motorway with no intrusive boom or cabin resonance. The matte black ceramic-finished outlets deliver a stealth, motorsport look that suits the G80 chassis perfectly.

Crafted in Britain from high-grade T304 stainless steel, the mandrel-formed pipework maintains a consistent radius for smooth gas velocity. A carefully optimised bore improves breathing over the factory setup, supporting response without sacrificing mid-range torque. It is a direct replacement for the rear muffler assembly, so you get a clean, bolt-on fit with OEM-like alignment and premium finishing throughout.
