The APR Race DP and Midpipes are the ultimate exhaust upgrade for the Audi 2.5 TFSI EVO! This system is sold in multiple configurations and is completely compatible with every component in the factory exhaust system, allowing you to customize the exhaust to your desire. We upgrade various components, which allow for better turbocharger response and power delivery, while delivering an enhanced 5 cylinder symphony you’ll love! Expect only the best components and highest quality and manufacturing techniques, and to fully enjoy the full system, get the APR Stage 2 ECU Upgrade at no charge over APR Stage 1/1+ with the included free upgrade code!
The APR Race Midpipes with Catalysts are both 2.5” and are designed as a simple plug and play upgrade. We use T304 stainless steel piping that’s brushed, mandrel bent, and TIG welded to the included catalyst and CNC machined ultra-flat OEM-style 3-bolt-flanges. The system includes new gaskets, bolts and copper plated nuts.
The system includes two proprietary 300-cell GESI high-flow catalyst, which are ideal for forced induction applications. They feature a fully captured substrate brick, which is furnace brazed to the outer mantle and physically captured by the diffuser cones. This helps to prevent rattling, rotation and damage to the substrate, especially on higher horsepower applications.
The APR Race Midpipes with Catalysts are compatible with the factory DP and our Race DP. Race Midpipes (catted or non-catted) are required for Stage 2 along with our Race DP.
