Valvetronic Designs Audi MK3 TTRS Valved System

Description

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.
