034Motorsport is proud to unveil the all-new Cast Stainless Steel Performance Downpipe for 8V Audi A3/S3 & MkVII Volkswagen Golf/GTI/R models equipped with EA888 Gen 3 1.8T/2.0T engines! Offering increased horsepower and torque throughout the powerband, reduced turbocharger lag, and enhanced exhaust note, this is the ultimate downpipe solution for the discerning Audi/Volkswagen enthusiast.

Optimized for increased flow and maximum performance, the MQB 1.8T/2.0T Cast Stainless Steel Performance Downpipe features organic geometry and a massive 101.6mm diameter Euro 3 racing catalytic converter in the factory location. This complete downpipe solution includes an integrated v-band flange at the turbine outlet, integrated oxygen sensor bung after the catalyst, OEM-style corrugated flex bellow, and factory-location exhaust hanger. The MQB 1.8T/2.0T Cast Stainless Steel Performance Downpipe is constructed from 304 stainless steel and TIG-welded for maximum durability and corrosion resistance.

034Motorsport's MQB 1.8T/2.0T Cast Stainless Steel Downpipe was developed entirely in-house on 034Motorsport's Development MkVII Volkswagen GTI & 8V Audi S3 utilizing the latest in 3D Scanning Technology, CAD Software, and Rapid Prototyping Techniques. Final production units were then tested extensively on multiple enthusiast-owned 8V Audi A3/S3 & MkVII Volkswagen Golf/GTI/R vehicles before release.
