Audi RS5 B8 B8.5 4.2L V8 Vortex Performance Exhaust System - Valvetronic N/A Scream

The 8,500 RPM Symphony Unleashed

The Audi RS5 (B8/B8.5) is home to one of the most iconic engines in automotive history—the high-revving 4.2L Naturally Aspirated V8. While the factory exhaust is refined, it hides the true, visceral scream of this 8,500 RPM masterpiece. The Vortex Performance Exhaust System is engineered to strip away those restrictions, delivering a spine-tingling, high-pitched exotic roar that pays homage to the golden era of N/A engines.

Key Performance Highlights

• The Ultimate High-Pitch Tone: Specifically tuned for the high-revving nature of the 4.2L V8. Our proprietary internal geometry amplifies the mechanical symphony of the engine, producing a crisp, high-frequency scream at the redline without the "muddy" bass of generic systems.

• Precision Valvetronic Control: Experience total duality. Utilizing high-performance valves, you can integrate directly with your Audi Drive Select. Keep it "Comfortable" and drone-free for highway cruising, or switch to "Dynamic" to let the V8 sing its heart out.

• Optimized Power-to-Weight: The stock RS5 exhaust is notoriously heavy. The Vortex system uses aerospace-grade T304 Stainless Steel or Grade 1 Titanium to slash weight by up to 40%, sharpening the car's handling and improving throttle response.

• Masterful Craftsmanship: Every system features hand-crafted TIG welding and a mirror-polished finish. It isn't just a part; it is a work of art designed to withstand the high-heat cycles of a performance V8.
