APR DPK0028 Race Downpipe Audi 8V RS3 and Mk3 TT RS
The APR DPK0028 Cast Downpipe replaces the restrictive factory downpipe with a larger free-flowing system. While adequate for the stock power levels, the OEM downpipe suffers from a sharp transition exiting the turbo, then right into a hot catalytic converter which dumps waste heat directly into the engine bay. From there the factory system splits into kinked piping, with less than 50mm of diameter on one side and ~58mm on the other. The APR system addresses these issues by using a port matched 102mm outlet which then smoothly transitions into the cast stainless Y-section to split the 102mm pipe into dual 63.5mm piping, moving the catalysts out of the engine bay. Expect better throttle response, significant power gains, and an intoxicating 5-cylinder exhaust note, while remaining civilized during normal daily driving.
The APR Race DP is compatible with the factory midpipes as well as APR midpipes. APR includes a Stage 2 ECU Upgrade code for a free upgrade from an APR Stage 1 tune to Stage 2.
