FLASHARK's S55 downpipes are designed to seamlessly fit in place of your restrictive stock downpipes on BMW M3 (F80) and M4 (F82/F83) models, which are situated immediately after your catalytic converters. Upgraded downpipes provide great increases in horsepower and torque on turbocharged vehicles by allowing exhaust gases to flow easier as they leave the turbo. The high-quality exhaust manifold can improve the exhaust airflow rate and ensure you have a better driving experience.

What does a Downpipe do?

The downpipe on your turbocharged vehicle directs exhaust gases out of the turbine housing and into the exhaust system. An aftermarket downpipe, like FLASHARK’s S55 downpipes for BMW M3 (F80) and M4 (F82/F83), is typically larger in diameter and either uses a high-flow catalytic converter or removes it entirely.

By replacing the restrictive factory downpipe with a high-flowing unit, you allow the turbo to expel gases more efficiently, resulting in increased power. With factory restrictions removed, boost levels can be safely increased, eliminating one of the key bottlenecks in your S55-powered BMW’s performance.
