PRODUCT DESCRIPTION
BMW F80 M3 S55 USA version downpipe, 3.0L twin-turbo, 2014+, 431 km
The downpipe is an essential component for optimizing any turbocharged car. After its installation, the exhaust system is optimized, resulting in a noticeable improvement in performance at low RPMs. This means the so-called "turbo lag" effect disappears, and power and torque increase. The Fmic.Pro Racing downpipe represents new quality and durability in exhaust system components. Our downpipes are made of high-quality stainless steel with 1.5 mm thick walls. Each component is precisely manufactured using CNC, ensuring the repeatability of the final product. The flexible connectors used in the downpipe's manufacturing have internal reinforcement, which significantly strengthens the entire structure and prevents internal suction.
Outer diameter: 70 mm
Flange thickness: 10 mm
The downpipe has the following connections:
- Two lambda sensor connections on each pipe
