Unleash the true motorsport character of your BMW E9X M3 with the Active Autowerke Signature X Pipe with Straight Pipes — engineered exclusively for track and off-road use. Designed as a direct bolt-on upgrade, this system delivers uncompromised flow, precision fitment, and a spine-tingling exhaust note worthy of the S65 V8.
Developed with decades of racing heritage, the Signature X Pipe eliminates both primary and secondary catalytic converters to maximize power output and throttle response. The refined X-section design enhances exhaust scavenging, improving mid-range torque and producing measurable gains of up to 12+ rear-wheel horsepower when paired with the Active Autowerke Signature Exhaust.
Crafted from premium 304 brushed stainless steel, the system offers exceptional durability and corrosion resistance while weighing nearly 40% less than the OEM unit — just 25 lbs versus 40 lbs stock. Installation is completely bolt-on, with factory-style flanges ensuring seamless integration with most aftermarket or OEM mufflers — no cutting, welding, or modifications required.
Features:
- Durable 100% 304 brushed stainless steel construction
- +12 RWHP gain when paired with AA Signature Exhaust
- Direct bolt-on with factory-style flanges — no cutting or welding
- 40% weight reduction over OEM system
