Audi MK3 TTRS 2.5L Catback T304 SS Black OEM Style Valvetronic Tips

The five-cylinder soundtrack is iconic—the factory cat-back just keeps it on too short a leash. The Valvetronic Designs Valved Cat-Back for the Mk3 TTRS increases system diameter to 3 inches for significantly improved flow and a sharper, more characterful note without sacrificing daily comfort. At the heart of the design is our rear Y-section: straight-through when valves are open for maximum presence, and routed through a quad-chamber center muffler when closed for quiet, refined cruising. The dream exhaust for Audi’s modern 5-cylinder is here.

• Brushed T304 stainless steel
• 3" from front to rear
• Weight Savings: 14.8 lb lighter than the factory exhaust.
• Uses OEM-style electronically actuated valves; compatible with OEM Audi valve control.
• Premium tips engineered to complement the TTRS rear bumper.
