Designed for turbocharged 1.8L / 1.8T applications, this high-flow performance downpipe replaces the restrictive factory-style exhaust section with larger-diameter, mandrel-bent stainless tubing designed to improve exhaust gas flow from the turbocharger.
The freer-flowing design can help reduce exhaust restriction, improve turbo response and support increased horsepower and torque when used as part of a properly configured performance exhaust system.
Constructed from T304 polished stainless steel with TIG-welded joints, CNC-machined connection components and mandrel-bent tubing for a smooth exhaust path.
✔ Designed for Longitudinal Audi / VW 1.8T Turbo Applications
