PRODUCT DESCRIPTION
DECAT Downpipe BMW F15, F85 N63N, S63R x5 50ix, x5 M 2012-2017 450, 575 hp
The downpipe is an essential component for optimizing any turbocharged vehicle. After installation, the exhaust system is uncorked, resulting in a noticeable improvement in engine response 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 carefully manufactured using CNC, ensuring product repeatability.
Outer diameter: 76.5 mm. Flange thickness: 10 mm.
The downpipe has the following connections:
- Two connections for the lambda sensor.
