Audi TTRS (Mk3) Valved Cat-Back Exhaust System

3" T304 Stainless Steel with OEM-Style Electronic Valve Control

Overview

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.

Why It Works

  • 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.

Sound & Control

  • 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.

Construction & Quality

  • 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.

Fitment

  • 2017–2020 Audi TTRS (Mk3 / 8S)

Installation Notes

  • Direct bolt-on cat-back; no permanent modifications required.

  • 100% reversible—return to stock at any time.
