Downpipe FMIC.Pro for Audi A4 S4 Avant Quattro 3.0 TDI 2016-2021

The downpipe is an essential upgrade for any turbocharged vehicle. Its installation helps to “unrestrict” the exhaust system, directly improving performance – faster turbo response, reduced turbo lag, and increased power and torque, especially in the low and mid RPM range. Additionally, a downpipe gives the exhaust system a deeper, more aggressive sound and improves the overall efficiency of the turbocharging system.

The FMIC.Pro downpipe guarantees the highest quality and durability. It is made from high-grade stainless steel with a wall thickness of 1.5 mm, ensuring full resistance to extreme temperatures and corrosion. CNC-cut flanges with a thickness of 10 mm provide perfect fitment to the turbocharger and the rest of the exhaust system, while TIG welding ensures strength and a clean, professional finish.
