Tightened noise regulations mean one of the most capable engines Audi builds spends most of its life sounding far quieter than it should. This system replaces the restrictive rear section with a free flowing design that lets the V8 breathe, unlocking the deep, hard-edged bark the standard car keeps hidden.\u003c\/p\u003e\n\u003cp\u003eAn independent Varex valve system, controlled by remote, puts you in complete control of how loud the car is at any moment. Closed, it is calm enough for a cold start in a quiet street. Open, it delivers the full V8 character under load.\u003c\/p\u003e\n\u003cp\u003eEvery section is manufactured from stainless steel and precision TIG welded throughout, built to handle the heat of a twin-turbo V8 while retaining the factory mounting points and tip positions for a clean, bolt on installation.\u003c\/p\u003e\n\u003cp\u003eWhether your car is otherwise standard or running downpipes and a tune, this system delivers the sound the platform is capable of while remaining completely usable every day.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003ch3\u003eIndependent Varex Valve System\u003c\/h3\u003e\n\u003cp\u003eRather than reusing the restricted factory valves, this system operates its own dedicated valve assembly with complete travel in both directions. Sealed when closed for quiet running, and fully unobstructed when open for maximum flow and volume.
