I just picked up my Audi RS3 FL Sedan with OPF from HPerformance. I got the 4-inch exhaust system and a Stage 3 upgrade. I’m just super happy with how it drives and, above all, how brutal it sounds despite the OPF. Everything worked great—I can really recommend it to anyone who loves their five-cylinder engine!!
TheStage 2 performance upgrade deliversover535 hpand700 lb-ft of torque.
Our Race Stage, with over 535 hp and 700 Nm, transforms the RS3 into a whole new experience. In addition to optimized fresh air flow through the intake, turbo inlet, and intercooler, we’ve equipped it with an uncompromising 4-inch (101.6 mm) racing downpipe, which drastically reduces backpressure and gets the turbo up to boost pressure noticeably faster.
The massive exhaust side ensures that the high boost pressures of this stage are consistently and reliably maintained at all times—while also delivering an aggressive, sharp sound. During gear shifts and load changes, it produces distinct burst-like pulses, accompanied by backfire moments that make the racing DNA of this stage unmistakable.
In addition to the hardware modifications mentioned above, an individual, fuel-specific software tuning on our in-house all-wheel drive test bench is of course included (incl. input and output measurement)

Free-flow! RACE Stage 2!
The RACE Stage 2 kit for the RS3 8Y delivers uncompromising performance on the track. The HP Sport Series intercooler, with optimized airflow channels, keeps intake temperatures stable even under maximum load and ensures consistent power output. The HP 4" aluminum intake (100 mm) noticeably improves airflow and significantly enhances throttle response.
This RACE upgrade uses a RACE downpipe without an OPF —for minimal exhaust backpressure, maximum flow, and an unadulterated, aggressive sound.
