BMW S58 Catless Downpipes - G80 M3 / G82/83 M4 / G87 M2

Free up maximum power and unleash the true sound of your S58 with the Catless Downpipes, designed for the G80 M3, G82/83 M4, and G87 M2. The restrictive factory catalytic converters create backpressure that limits performance and mutes exhaust tone. By replacing them with high-flow catless downpipes, you’ll experience dramatic improvements in horsepower, torque, and turbo spool while unlocking a raw, aggressive exhaust note.

Built from premium T304 stainless steel, these downpipes feature smooth mandrel bends and precision welds for optimal exhaust flow and long-term durability. The result is quicker turbo response, reduced turbo lag, and the ultimate in performance gains—making them the perfect upgrade for both street and track builds.

✅ Maximum performance gains – increased horsepower and torque
✅ Faster turbo spool – reduced lag with sharper throttle response
✅ Aggressive exhaust tone – raw, motorsport-inspired sound
✅ T304 stainless steel – strong, durable, and corrosion resistant
✅ Direct bolt-on fitment – works with OEM or aftermarket exhaust systems
