Unleash the captivating exhaust symphony of your G80 M3/M4 with the ARM S58 Midpipe upgrade. Eliminating the two middle resonators dramatically enhances the S58-powered BMW's sound profile. You retain control over the exhaust flaps, enabling you to switch between a subdued tone and a powerful roar while keeping the OEM muffler. This mid-pipe elevates the volume and transforms the ordinary G80 M3 into something extraordinary. Even with OEM tuning, it amplifies the delightful exhaust burbles. 

Crafted from SS304 stainless steel, the ARM S58 Midpipes have a lifetime warranty. They feature OEM-style 2-Bolt flanges, ideal for compatibility with OEM and upgraded downpipes. Alternatively, you can opt for the ARM S58 Crossover Pipe, shedding weight and enhancing sound. The sonic alchemy occurs in the X-Pipe section, blending the S58 engine's sound waves for a richer, more exotic exhaust note.

This upgrade seamlessly integrates with the OEM brace, and the path leads back to the OEM muffler, allowing full use of the exhaust valves. Take control of your G80 M3/M4's sound with the ARM S58 Midpipe upgrade.
