Description
Active Autowerke proudly presents the Signature X-Pipe with GESI G-Sport Ultra High Flow Cats, designed specifically for the BMW E9X M3. This performance exhaust upgrade is engineered to work seamlessly with most aftermarket exhaust systems or mufflers, requiring no cutting, welding, or modifications—making it a true bolt-on solution for your M3.
The improved scavenging effect of the Active Autowerke X-Pipe results in significant horsepower gains, with an additional 12+ RWHP when paired with Active Autowerke's Signature Exhaust System and 10+ RWHP with the stock BMW exhaust. Plus, this X-Pipe offers dramatic weight savings, shedding 15 lbs compared to the stock system.
Constructed from 100% 304 brushed stainless steel, the X-Pipe is durable, rust-resistant, and designed to last. The system includes two 4" GESI catalytic converters that are EPA registered, OBD2 compliant, and rated for engines producing 300 to 500 horsepower. These high-flow cats reduce back-pressure, allowing your engine to reach its maximum potential without triggering a Check Engine Light.
