Description
The Active Autowerke G80/G82 Exhaust Bundle A-Flow Equal Length Resonated is a complete, performance-focused exhaust solution engineered to dramatically improve exhaust flow, sound balance, and overall driving engagement on BMW G-series M cars. This bundle combines three of Active Autowerke’s most advanced exhaust components into one cohesive system, delivering maximum performance and value.
At the rear, the Active Autowerke valved exhaust system retains factory valve functionality while producing a deep, aggressive exhaust note under throttle and a refined tone during normal driving. The system is designed to reduce backpressure while maintaining excellent fitment and daily drivability.
Upstream, the bundle includes Active Autowerke A-Flow catted downpipes, known for their industry-leading flow characteristics. These high-flow catalytic converters significantly improve exhaust velocity and throttle response while remaining suitable for street use.
Connecting everything is Active Autowerke’s patented equal length resonated midpipe. This midpipe is engineered to balance exhaust pulses from both banks, reducing rasp and drone while producing a smoother, more exotic exhaust tone. The integrated resonators further refine sound quality without sacrificing performance.
All components are designed to work together as a complete system, offering substantial gains in horsepower, torque, and sound quality over the factory exhaust configuration. This bundle is ideal for enthusiasts looking for a premium, well-engineered exhaust upgrade backed by Active Autowerke’s proven BMW performance expertise.
