11-115FB - Active Autowerke Performance Valved Rear Exhaust - Generation 2 - Black Tips
Active Autowerke Performance Valved Rear Exhaust - Generation 2 - Black Tips
Dial In B58 Sound and Performance — the Turner Way
Looking for a noticeable bump in sound and flow without replacing the entire exhaust system? The Active Autowerke Gen 2 Rear Exhaust for B58-powered BMW models delivers meaningful gains in a clean, well-engineered package. This rear section focuses on improving exhaust efficiency and tone while maintaining the refinement and daily usability expected from a properly sorted BMW.
At the heart of the system is a straight-through muffler design that reduces backpressure versus the restrictive factory unit. The result is improved horsepower and torque, particularly through the midrange where the B58 responds best. With the factory valve open, the exhaust produces a more aggressive sport tone. Close the valve and the sound remains controlled and comfortable for everyday driving.
Construction is centered on durability and proper fit. Large mandrel-bent tubing and a brushed 304 stainless steel body provide long-term corrosion resistance and consistent flow. Double-walled signature tips — available in brushed, black, or carbon stainless — finish the rear with a clean, purposeful appearance.
Installation is straightforward thanks to height-adjustable mounting brackets and the inclusion of a heavy-duty TORCA-style clamp, known for its strong sealing capability and secure fitment.
Independent testing shows gains of approximately 12–15 horsepower over stock while reducing overall weight compared to the factory rear exhaust.
