Valvetronic Designs Audi TTRS MK3 Valved Sport Exhaust System
$2,499.99
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.
- Valves Open: Uninterrupted flow to the tips—crisp, aggressive 5-cylinder character.
- Valves Closed: Gas passes through the quad-chamber center muffler—significantly reduced volume, highway-friendly.
- OEM Integration: Uses OEM-style electronically actuated valves; compatible with OEM Audi valve control.
- Material: T304 stainless steel throughout.
- Craftsmanship: Precision TIG welds and fully mandrel-bent tubing.
- Weight Savings: 14.8 lb lighter than the factory exhaust.
- Finish & Tips: Premium tips engineered to complement the TTRS rear bumper.
- 3" Free-Flow Architecture: Reduces back pressure and unlocks response through the rev range.
- Dual-Path Rear Y-Section: Straight-through (open) or muffled (closed) for two distinct personalities.
- System Tuning as a Whole: Designed as a cohesive cat-back for consistent tone and perfect fit.
