SuperSprint Turbo Downpipe with Metallic Sport Cat, 118mm Inlet, BMW N55

The stock exhaust system for the 235/335/435 N55 models is generally unrestricted, except for the catalytic converter, which serves as a significant bottleneck. To enhance power output, upgrading the exhaust necessitates replacing this restrictive component with a more efficient alternative. Supersprint's downpipe features an ultra high-flow HJS 100 or 200-cell metallic catalytic converter, offering significantly improved flow compared to the stock ceramic counterpart. Additionally, it utilizes larger 80 mm piping to further reduce restrictions.

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.

100-cell cats have 100 honeycomb cells per square inch. While still cleansing the exhaust somewhat this is basically a straight-through exhaust.

200-cell cats have 200 honeycomb cells per square inch. This is much better flow than stock but still does a good job of cleansing the exhaust.
