AUDI MK3 TTRS POLISHD EXHAUST BLACK

This 3-inch valved cat-back system for Mk3 TTRS / RS3 enhances the five-cylinder sound, increases flow, and offers a sharper, aggressive note while maintaining daily driving comfort. It features a dual-path rear Y-section with straight-through flow when valves are open, and routes through a quad-chamber center muffler with valves closed for a quieter experience. Made from T304 stainless steel with precision TIG welds and mandrel-bent tubing, it is 14.8 lbs lighter than OEM and uses OEM-style electronically actuated valves compatible with OEM Audi valve control. The system is 100% reversible.
