Show original supplier description
The Milltek Sport SSXBM1319 is a high-performance secondary cat-back exhaust system engineered to amplify the sound and refine the driving experience of the BMW M3 G80 and M3 Competition (S58 3.0 Turbo, GPF-equipped models). This system, featuring a 3.15-inch (80mm) pipe diameter and distinctive GT-115 brushed titanium trims, replaces the factory particulate filter-back components. Constructed from premium T304L aircraft-grade stainless steel, the SSXBM1319 offers exceptional durability, resistance to corrosion and heat, and a refined aesthetic. Its design improves exhaust flow efficiency, which can lead to sharper throttle response and a more engaging, motorsport-inspired exhaust note. The system is intended to integrate seamlessly with factory GPF-equipped exhaust systems, providing an OEM-style upgrade path. It is not an EC approved or race system, and does not feature valve sonic technology. The system is compatible with BMW 3 Series G80 M3 and M3 Competition (S58 3.0 Turbo, GPF Equipped Cars Only) & XDrive Models, and BMW M4 G82 models from 2020 onwards. Compatibility is listed for specific model years including 2020-2026 for the BMW 3/4 Series G80/G82 M3/M4, and 2021 models for the BMW M4 Coupe.
