Description

The Valvetronic Designs Full Valved Exhaust System for the Audi B9 S4 and S5 (EA839 3.0L V6) provides an aggressive, motorsport-inspired tone with valves open and stock-like refinement with valves closed. It is a complete, one-piece T304 stainless steel system, 16.4 lbs lighter than OEM, with electronic valve control, mandrel-bent construction, and brushed 3.5-inch outlet tips. It is designed to be a direct-fit for sedan models, while coupe models may require modification to the mid-section for proper fitment.
