Transform the sound and character of your BMW with the Active Autowerke Signature Equal Length Midpipe for the G87 M2, engineered to deliver a smoother, more refined exhaust tone while restoring the true sound expected from the S58 platform. Featuring patented equal length technology and newly developed Gen 2 resonator design, this system corrects factory exhaust imbalances and enhances both sound quality and overall driving experience.
Key Features:
- Patented equal length midpipe design (US Patent 11248511)
- Gen 2 advanced resonators to reduce rasp and unwanted frequencies
- Constructed from 100% 304 stainless steel
- Smoother, more refined high-rev exhaust tone

- Compatible with factory-style exhaust systems
- Includes Active Autowerke G87 chassis brace

True Equal Length Sound Engineering
BMW’s factory exhaust system partially attempts an equal length configuration but results in an imbalance between the left and right exhaust paths. Active Autowerke’s patented design corrects this by properly equalising both sides, delivering:
- A smoother, more consistent exhaust note
- Improved tonal balance across the rev range
- A more authentic BMW M sound profile
Gen 2 Resonator Technology
The updated Gen 2 midpipe introduces specially engineered resonators designed to:
- Reduce harsh rasp commonly associated with S58 setups
- Minimise unwanted “2k RPM buzzing”
- Improve cold start sound refinement
- Maintain volume while enhancing tone quality
For optimal results, the resonated version is recommended for vehicles running upgraded downpipes.
Premium Stainless Steel Construction
Manufactured from high-grade 304 stainless steel, this midpipe ensures:
- Long-term durability and corrosion resistance
- Consistent performance under high temperatures
- High-quality finish and structural integrity
Designed for Seamless Integration
This system is designed to work with factory-style exhaust configurations and many aftermarket systems using OEM-style connections. Installation requires minimal modification, with only two cuts needed to the original midpipe, allowing for a reversible upgrade if required.
