Flange shaft - 0CP 409 356 A - Genuine spare part for Audi RS3 8Y

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!!

I'm gradually modifying my RS3 8Y. So far, I've installed the 4" exhaust system and 5" intake. The quality is just amazing. I've been in touch with them several times now—they're super friendly and helpful.

I took my Audi RS 3 8Y to H Performance for a Stage 1 upgrade. From the very beginning, I felt they took excellent care of me. Their advice was extremely knowledgeable, and their communication was always friendly and professional. The increase in power far exceeded my expectations. I was even able to be there for the power test. I’m already looking forward to the next projects. Best regards to the entire H Performance team!

DSG Catch Tank - Machined aluminum - RS3 TTRS RSQ3 - DAZ DNW CZG. Delivery was fast; the catch tank is beautifully crafted and fits very well in the engine compartment of my RSQ3 Sportback. I would buy it again in a heartbeat.

We drove all the way from Hamburg in our Audi RS3 8Y facelift to visit these very nice guys and girls. What they do there is incredible—we opted for the Stage 2 upgrade with 520 PS. Everything was installed very professionally, and they treated the car with the utmost care. The value for money is incredible; we can recommend them with a clear conscience. You really feel like you’re in good hands there. The drive back was even more fun than the drive there—thanks so much for that. Best regards from Hamburg!!!

So, the guys at HPerformance are absolutely amazing 🥳. I stopped by with my green Audi RSQ3 and had them install new Stage 2 engine and transmission software. I have to say, I’m completely blown away 🤩 by how it runs now and its responsiveness. I’d had what was supposedly a Stage 2 setup installed before, but it was nothing but trouble—they had to fix it five times, and in the end, it didn’t deliver on the promised performance at all☹️. But the guys at HPerformance put a huge smile on my face. 🤩 It’s just fun again to drive this beast 💥💥💥.

Great store, everyone was very friendly. Parts were ordered quickly. RS3 Chipbox 5-inch intake—top quality. More parts to come. Best regards, Julian

I was just passing through when my T7 made a really loud clunking noise from the front left. Even though the shop was packed and there was a customer waiting—who was very understanding—the guys still took care of my issue. Luckily, it was just a loose tie rod. A thousand thanks to the awesome team—you guys have an incredibly great shop 🫶🤩
