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!!
HPerformance Plug'n'Play Downpipe - Maximum performance for your Audi S4 & S5 B9 ( B9.0: 2016-2019)
Downpipes without catalytic converters (catless), specially developed for the powerful 3.0 TFSI V6 engine
More power, more sound & less back pressure
These downpipes provide a noticeable increase in performance and a distinctive sporty sound. By dispensing with the original OPF, the exhaust back pressure is drastically reduced, resulting in thermal relief for the turbo, lower exhaust temperatures and improved response.
Perfect fit & high-quality workmanship
Thanks to the original flanges and connections, the downpipes fit perfectly to the existing turbos - completely without adjustments. Manufactured from high-quality 304 stainless steel and precision TIG-welded, they guarantee a long service life and optimum performance. Our downpipes are also thermally insulated as standard.
