Milltek – Downpipes. Fits BMW M4 G82/G83.
If you're a proud owner of a 2021-2023 BMW 4 Series G82 M4 or M4 Competition with the S58 3.0 Turbo, the Milltek Sport SSXBM1171 is a must-have upgrade for your performance machine. With over 20 years of exhaust development expertise, Milltek has crafted a system that not only enhances performance but also transforms your driving experience.
This axle-back exhaust system is engineered for optimal gas flow, thanks to mandrel-bent tubing that reduces restrictions and increases bore size. Expect noticeable power gains and a sound that will turn heads without being overly aggressive. It strikes the perfect balance between performance and style, allowing your M4 to roar when you want it to and remain discreet during everyday drives.
One M4 owner shared, I installed the Milltek exhaust on my 2022 M4, and the sound is just incredible! It added just the right amount of aggression without being obnoxious. Plus, I noticed a nice bump in torque that makes driving even more fun.
Upgrade your BMW M4 with the Milltek Sport SSXBM1171 and experience the difference in performance, sound, and style. This is more than just an exhaustit's a performance enhancement that you can feel on the road and track.
