Product Details
Sharper Sound. Real Performance. OEM-Plus Execution — the ECS Tuning Way
If you’re looking to wake up your B58-powered BMW without committing to a full exhaust overhaul, the Active Autowerke Gen 2 Rear Exhaust delivers exactly where it counts. Designed as a compact, high-value solution, this system improves exhaust flow, enhances tone, and sheds weight — all while retaining factory functionality and daily drivability.
Built around a straight-through muffler design, this system significantly reduces backpressure compared to the restrictive factory unit. The result is measurable horsepower and torque gains, especially through the midrange where the B58 really lives. With the factory valve open, the exhaust delivers an aggressive, wide-open sport note. Close the valve and the tone settles into a refined, mellow character suitable for daily driving.
Construction quality matches the performance. The system features large mandrel-bent piping and a durable brushed 304 stainless steel body for long-term corrosion resistance. Double-walled signature tips — available in brushed, black, or carbon stainless — complete the rear with a clean, purposeful look.
Installation remains straightforward thanks to height-adjustable mounting brackets and the use of a heavy-duty TORCA-style clamp, known for superior sealing and clamping strength compared to traditional exhaust connections.
Tested and proven, this rear section provides solid gains of approximately 12–15 horsepower over stock while dropping roughly 5 lbs versus the factory exhaust.
