Sound & Control
Valves Open
With the valves open, the 3.0-liter supercharged V6 finally finds its voice — a raspy, mechanical snarl accented by audible supercharger whine that intensifies with RPM. The blower's characteristic whistle layered over the V6's naturally smooth exhaust tone creates a distinctive, addictive sound signature that is uniquely supercharged. Full-throttle acceleration produces a hard-edged growl with real presence, and lift-off delivers satisfying burble and pops that the factory exhaust completely eliminates.
Valves Closed
Valves closed, the S4/S5 returns to its role as the consummate gentleman's express. The exhaust note drops to factory-quiet levels, cold starts are virtually silent, and highway cruising remains smooth and drone-free. This is the mode for client meetings, school runs, and neighborhood departures — the S4/S5's stealth persona fully intact and indistinguishable from stock.

Valvetronic Designs Audi B8 / B8.5 S4 / S5 Valved Exhaust System
Awaken the Supercharged V6 — From Subtle to Savage
The B8 and B8.5 Audi S4 and S5 introduced one of the most underrated powertrains of their generation — a 3.0-liter supercharged V6 that delivered effortless, linear power with a mechanical forced-induction character that turbocharged engines simply cannot replicate. The supercharger's instant boost response, combined with Quattro all-wheel drive and Audi's refined chassis tuning, created sports sedans and coupes that punched well above their weight class. But Audi's acoustic philosophy for the S-line prioritized subtlety to an extreme degree — the factory exhaust rendered the supercharged V6 nearly silent, stripping the driving experience of the emotional engagement the powertrain deserved.
The Valvetronic Designs valved exhaust system for the B8/B8.5 S4 and S5 corrects that imbalance with precision. Available in T304 stainless steel or titanium, the system's electronically actuated butterfly valves reveal the supercharged V6's naturally aggressive voice on demand while maintaining Audi's signature refinement when you need it. An Audi S4 Valvetronic exhaust gives the B8 platform the dual personality it was always missing — the one upgrade that makes you fall in love with the supercharged V6 all over again.
