Valvetronic Designs, born in the heart of Pennsylvania and engineered for automotive enthusiasts worldwide, is where precision meets passion. The company crafts high-performance valved exhaust systems that do more than just roar - they respond. With the push of a button, drivers can transform the personality of their car, shifting from stealth to symphony, from whisper to wild. Built on a foundation of ingenuity, Valvetronic's exhaust systems are designed, developed, and manufactured in the USA. Every weld, every valve, and every resonance is refined for performance, durability, and unmistakable character. Whether outfitting supercars, track machines, or street legends, Valvetronic ensures the sound always matches the drive.
Transform your supercharged V6 into a true auditory experience. Our Valvetronic Designs Valved Exhaust System for the Audi B8 and B8.5 S4/S5 delivers a unique, high-pitch wail while retaining low-end rawness for a sound profile unlike anything the platform has heard before.
Constructed entirely from T304 stainless steel and featuring our high-pitch X-pipe technology, this system runs 2.5 inches from front to rear, unlocking an exhilarating tone across the entire rev range. With integrated vacuum-actuated valves controlled via an included key fob remote, you have instant flexibility to switch from refined cruising to an aggressive, motorsport-inspired soundtrack.
