Show original supplier description
The M-TECH BMW S58 Downpipe and Midpipe Bundle is engineered to unlock the full performance potential of your BMW M-series vehicle. This high-performance bundle combines the MTech S58 Downpipe and MTech S58 Midpipe, providing a comprehensive exhaust upgrade that increases horsepower, torque, and overall engine response. It also delivers a deep, aggressive exhaust sound with minimal drone, enhancing the driving experience. Key features of this bundle include construction from premium 304 stainless steel for superior durability and corrosion resistance, precision TIG welding for maximum flow, and a direct bolt-on design for straightforward installation. The system is engineered in-house and is compatible with both OEM and aftermarket exhaust systems. Important notes for installation and operation: OEM “circle ring” gaskets must be reused as they are not included. It is recommended to have your ECU DME unlocked to prevent check engine codes due to the free-flowing exhaust, and this product is intended for OFF-Road Use Only. Vehicle Fitment: - BMW M2 (G87) – 2023 and newer - BMW M3 (G80) – 2021 and newer - BMW M4 (G82/G83) – 2021 and newer
