True automotive passion comes in many forms. For us, we've found driving euphoria with our new ECS Valved Exhaust System. 

Enjoy your C7 RS7 with the most engaging, race-inspired, performance-valved exhaust system. Intoxicating exhaust notes fuel your desire to push your engine to its limits with every ounce of power and every engine revolution. Experience your driving passion with our ECS Valved Exhaust System allows for MMI control and operation of the valves

The full exhaust system is made from high quality brushed T304 stainless steel with TIG welded joints for an exceptional look and durability. Exhaust gases are channeled through the integrated x-pipe, your choice of either a resonator or a resonator delete section, and then to the 3 chamber, in house designed mufflers. With this system, you, the driver, are in control of where the exhaust gases go from here. 

In normal, comfortable driving conditions, the valve remains closed and exhaust gases are directed through the channels of the mufflers, where sound reduction takes place. Once the exhaust valved are opened it unleashes a straight-through, raw, unedited exhaust symphony.

When paired with our standards of quality and design requirements here at ECS Tuning, we can provide your C7 RS7 a perfect blend of performance and an interactive driving experience. Through multiple design iterations and stringent product testing, we have engineered our exhaust system to not only free up horsepower but to provide trouble-free installation.

Our ECS Valved Exhaust System was designed, engineered, tested and quality inspected by our Research and Development team in our Wadsworth, Ohio facility. We strive for the highest level of precision and quality through leading-edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long term product testing.
