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!!
's Stage 2 performance upgrade delivers power outputs exceeding 535 PS and 700 NM.
We achieve our Stage 2 with 535PS and 700NM with our 4-inch 101.6 mm OPF-TÜV downpipe in addition to the fresh air-side modifications to the intake with turbo inlet and intercooler. The boost pressures required for 535 hp and more need to be relieved on the exhaust side in order to be able to call up the power reproducibly. Since the OPF models in particular require Temperature and Exhaust back pressure (exhaust gases escaping from the turbocharger, which create back pressure in the exhaust tract), we only use our 4" 101.6 mm downpipe with underfloor OPF and catalytic converter modules on these models. This enables us to achieve 0.3 bar less in backpressure compared to the 88.9 mm. In addition to providing thermal relief, the downpipe also delivers a robust and deep sound.
In addition to the hardware modifications mentioned above, the package naturally includes a customized, fuel-specific software tuning performed on our in-house all-wheel-drive test bench (including initial and final measurements).
No hidden costs—hardware installation, vehicle-specific software tuning, and TÜV registration INCLUDED!
Hardware changes:
- HP Sport Series intercooler
- HP 4" 100 mm aluminum intake (select option)
- HP 4" 100 mm aluminum turbo inlet
- Sports air filter insert
- HP 4" 101.6 mm OPF-TÜV downpipe
Software changes:
- Adjustment of all performance-relevant maps on our all-wheel drive test bench
- Adjustment of oil and exhaust gas temperature, component protection functions
- Increasing the V-Max according to the installed brake system
- Test drives in real operation for data recording
Please note:
For the tuning, you can either use your vehicle's existing control unit or opt for an additional, new control unit.
If the existing control unit is used, it will be customized and programmed.
With a new control unit, the original control unit remains fully intact, allowing for reversal at any time. This option carries an additional charge of €1,799.
The delivery or lead time will not change as a result of selecting the new control unit.
If you would like the option with a new control unit, please contact us before making your purchase.
Please note: Performance and acceleration values can be influenced by various external influences, fuels or additional hardware installed and ultimately the general condition (including mileage) of the engine. The values given are for guidance only and are not binding. With regard to legality and approval in the area of the StVZO we refer at this point to our general terms and conditions.
Freeflow! Stage 2!
With the new Stage 2 for the RS3 8Y, HPerformance is consistently taking the next step – technically advanced, thermally optimized and emotionally even more intense.
The in-house HP Sport Series intercooler, featuring optimized airflow channels, keeps temperatures stable even under heavy load, ensuring consistent performance. The HP 4" aluminum intake (100 mm)—available in additional variants as an option—significantly improves airflow and noticeably sharpens responsiveness.
New to this upgrade package is the TÜV-certified 4" OPF downpipe with a 100 mm diameter. It reduces exhaust backpressure, relieves thermal stress on the system, and delivers a more powerful, exhilarating sound—all while being legally approved for use on public roads by TÜV.
The result is a well-thought-out Level 2 with technical depth and emotional appeal – made for everyone who wants to not just ride performance, but feel it.
