Race DP

APR Race DP

The APR Race DP features a port-matched outlet connected to a smooth, 4” continuous-radius cast-bend, with an ultra-smooth cast-Y that splits the system into a dual 2.5” exhaust path. In contrary, the factory DP has a sharp transition exiting the turbo, which dumps directly into a massive and hot catalyst that keeps your engine bay toasty. From there the system splits into kinked piping, with less than ~2” of diameter on one side and ~2.3” on the other. The factory system wasn’t designed with ultimate performance in mind like our system.

Exhaust Exhaust Exhaust

The system is made from T304 stainless steel. The cast Y is electropolished, and all non-cast piping is mandrel bent with a brushed finish. As always, we only use argon-backpurged TIG welding techniques to assemble the systems.

Exhaust Exhaust Exhaust

The system features precision laser cut brackets with integrated PIM nuts for a reliable connection to the factory bracket. Our CNC machined v-band and OEM-style 3-bolt-flanges are precision cut and extremely flat ensuring an accurate seal. We include new gaskets and copper plated nuts as well.  Both O2 sensors bungs are cast and welded on top of the system in such a way as to prevent from protruding into the exhaust flow path. Lastly, we use OEM-style flex sections that are fully sealed with a corrugated inner liner for improved airflow. This design also resists billowing, rubbing, rattling and fraying, as is common with other types of flex sections.

The APR Race DP is compatible with the factory midpipes and our midpipes. This component, and APR Race Midpipes, is required for Stage 2, and includes a free authorization code to upgrade from APR Stage 1 or 1+ to Stage 2 at no additional charge.

 

APR Race Midpipes with Catalysts

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.

Exhaust Exhaust Exhaust

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.

 

APR Race Midpipes without Catalysts

The APR Race Midpipes 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 CNC machined ultra-flat OEM-style 3-bolt-flanges. The system includes new gaskets, bolts and copper plated nuts.

Over Stock
- APR recommends and tuned with Sunoco GT 260 for 100 AKI mode and Sunoco GT 260 Plus for 104 AKI mode. Never use lower octane than specified by the mode.
- E85 software is not a full flex fuel program. In this mode the engine is only designed to work on E85, as found directly at the pump, including both summer and winter blends from E60-E85. Using traditional pump fuels in this mode may result in engine damage. Do not manually blend with traditional pump fuel or race fuels. To ensure proper E85 content levels, APR recommends using an E85 content sensor.
- Max increases are based on APR's actual measured stock values and not those reported by VAG. | RON = ROW Fuel Grades | AKI = North American (RON+MON)/2 Fuel Grades.
- Reported wheel figures measured on APR's in house Dynamometer with a US Spec 2018 RS3, using SAEJ1349 correction and an average of multiple runs. Crank figures are estimated based on the measured wheel figures. Results may vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications. On the dyno, this platform will see large swings in power based on intake air temperature, and the gear in which it's dynoed.
