PROFILE

The MBS G8X S58 Resonated Heatshield Downpipe is engineered to unleash the true performance potential of your S58-powered BMW by maximizing exhaust flow and minimizing backpressure. The integrated heatshield design not only improves thermal efficiency but also protects surrounding components from excessive heat.

Upgrading to this downpipe delivers noticeable horsepower and torque gains, faster turbo response, and a more aggressive exhaust note—perfect for drivers looking to pair it with Stage 2+ tuning for maximum results.

Crafted from premium SS304 stainless steel, the MBS S58 Downpipe is built for durability and corrosion resistance. It’s designed as a direct bolt-on upgrade, compatible with both OEM and aftermarket midpipes, as well as stock or upgraded turbos.

For S58 owners who want more power, better sound, and improved efficiency, this is the first upgrade you should make.
