This performance system features 76mm (3-inch) REMUS tubing, upgraded from the original 70mm diameter, designed to maximize exhaust flow and enhance engine performance for BMW M-series applications.

Key Features:

• Includes additional original BMW actuator and Y-cable for connecting both actuators with the vehicle's onboard electronics
• Delivers additional 8.7 horsepower and 9.2Nm of torque gain
• Features dual integrated valves that activate using the original vehicle electronics
• Shot blasted surface finish, 100% stainless steel construction
• No rear skirt modifications required
• Comes complete with all necessary mounting hardware and installation instructions
• Aggressive racing sound optimized for BMW B58 turbocharged engines

Important Installation Note: The original exhaust will need to be cut during installation. This is a racing product without EC approval and is not permitted for use on public roads—intended for motorsport events and closed-track use only. An ECU remapping is recommended to exploit optimum performance and prevent check engine light activation.

Backed by Remus's reputation for precision engineering and premium materials, this exhaust system delivers the perfect combination of performance gains, aggressive sound character, and exceptional build quality that enthusiasts demand.
