The Gold standard in exhaust systems. 100% CAD designed and acoustics tested for an unparalleled sound experience.
Based in Quakertown Pennsylvania Valvetronic Designs is the leader in flexible exhaust solutions for all vehicles. We never compromise, neither should you.
Welcome to 5 cylinder fury. Both the TTRS and RS3 are extremely potent out of the box but lack some character when it comes to the extremely restrictive catback section of the exhaust. We fix that. Increasing the diameter of the system to 3 inches allows for significantly more flow through the system and towards the rear is where the magic happens.
The rear section y section is where the magic happens. When operating in the valves open mode the exhaust exits uninterrupted out of the massive exhaust tips. When closed the exhaust gasses pass through our quad chambered center muffler to lower sound levels significantly. The dream exhaust for the Mk3 5 cylinder cars is finally here.
Available in your choice of Polished SS or our Signature Anodized Gold (coating will take an additional 2 weeks)
