This system replaces it with mandrel-bent 304 stainless tubing and a valved rear muffler, so the car stays civil on a cold start in a quiet street and opens up completely the moment you want it to.\u003c\/p\u003e\n\u003cp\u003eThe valves are operated from a supplied remote, so the volume is your decision rather than something the throttle position decides for you. Closed, it is close enough to standard for an early morning. Open, it is a different car entirely.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\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.
