Audi S4 (B8.5) w/ F1 sound courtesy of Armytrix Valvetronic Exhaust System

Throw the ARMYTRIX performance valvetronic exhaust system on the Audi S4, just sit back and watch the world burn! Chrome quad-tip exits for maximum performance and auditory experience; 119dB with the valves fully open and 91.8dB with the valves closed, for a more civil approach. Awesome power-ups in both horsepower and torque from our stainless steel system for a new and incredible driving experience.

Valves opened (Race mode): Improved low level tone, amplified mid-range note, increased high pitch acoustics, sharper, crisper, sound across the rev range, noticeable Bhp gain typically, low/mid-range torque increase, sharper throttle response, performance efficiency, vastly freer flowing than OEM

Valve closed (Street mode): Keeping it low profile without getting attentions from the police and disturbing your neighbors, perfect for someone who doesn't want to be loud all the time,

Valve auto adjustment (Auto mode): Auto modulate back pressure levels, maintain backpressure at low rpm when launch-start without losing power
