For over 40 years, Active Autowerke has been at the forefront of BMW performance, and the G4X M240i axle-back exhaust represents the pinnacle of that development. This system is constructed entirely from TIG-welded 304 stainless steel, offering maximum resistance to corrosion and heat cycles. Unlike universal systems, this exhaust is engineered specifically for the G42 chassis, ensuring that every hanger and flange aligns perfectly. By retaining the factory valve control, this exhaust offers a "no-compromise" solution: it stays quiet and sophisticated when you need it, but opens up for maximum volume and performance when you want it. Each kit is a comprehensive package, providing all hardware required to transform your M240i’s rear section.
Key Features:
Surgical Precision: Every unit is test-fitted on a dedicated fixture to ensure zero-clearance issues with the chassis or diffuser.
Premium Materials: Full 304 Stainless Steel construction ensures a lifetime of performance.
OEM Integration: No need for extra wiring or controllers; works seamlessly with your car's computer.
Aggressive Rear Stance: Fills the rear bumper cutouts more effectively than the stock rectangular tips.
Performance Gains: Improved exhaust scavenging contributes to a more responsive B58 engine.

Type: Valved Rear Axle-back Exhaust Section
SKU: 11-125
