SuperSprint Stepped Section 1 with Metallic Sport Cats, BMW E46 M3

These Supersprint metallic sport cats are specifically designed for the E46 M3 when paired with Supersprint's own stepped headers. Featuring slightly oversized piping and significantly improved flow compared to traditional stock catalytic converters, these sport cats reduce exhaust gas restriction. This reduction in restriction translates to increased horsepower and torque, as the engine expends less effort to move exhaust gases. These catalytic converters are compatible only with the Supersprint full stepped headers and can be connected to any section 2. They come equipped with pre-installed O2 sensor bungs after the catalytic converter, allowing for the extension of stock post-cat O2 sensors (although special software may still be required).

Supersprint exhaust is the top choice for exhaust system upgrades, boasting exceptional quality, optimal flow design, and captivating sound. Supersprint sets itself apart by delivering every aspect to the highest standards, rewarding users with outstanding sound, durability, and precise fitment. Most systems are modular, allowing customization of the exhaust sound to personal preference. Additionally, Supersprint mufflers meet European noise regulations, providing a refined sound without excess loudness. Featuring larger diameter piping to enhance exhaust flow, Supersprint exhausts reduce engine workload for increased horsepower. While Supersprint exhausts may come at a premium, their unmatched quality, performance, and reputation make them unrivaled in the market.

Supersprint sources its metallic sport catalytic converters from HJS of Germany, a global leader in sport cat technology and performance. Supersprint collaborates closely with HJS to develop catalytic converters tailored to specific vehicles and engine packages, allowing for a substantial increase in flow.
