  • SKU
The APR Cast Downpipe Exhaust System replaces the restrictive factory downpipe and chambered resonator with a larger, 76mm stainless steel mandrel-bent system, featuring a bell-mouth cast inlet, high-flow catalyst and various other features. Expect better throttle response, more horsepower and an intoxicating exhaust note, while remaining civilized during normal daily driving. It’s one of the best performance upgrade for the 1.8 TFSI and 2.0 TFSI following the APR ECU Upgrade and it’s all designed and assembled in-house, using premium materials and world-class manufacturing techniques few can match.

For the best results, APR recommends installing the APR Stage II ECU Upgrade. The Stage 2 ecu upgrade price is waived for APR Stage I ECU Upgrade customers with purchase of the APR downpipe.
