Audi S4 B8.5 with Armytrix performance exhaust-inspire your every drive!
Our Audi S4 customer uploaded his normal drive video with Armytrix valvetronic exhaust. The video shows that Armytrix exhaust is practical for regular use with no resonate or drone inside the car. In addition, the exhaust sound was sharper and crisper across the rev range, but keep quite at the low RPM. The bombing downshift sound is definitely unforgettable!
