ECS Tuning B5 S4 Valved or Non-Valved Cat Back Exhaust

Valved Exhaust System

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

Enjoy your B5 S4 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 key fob operation of the valves to open or close them at the press of a button

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, your choice of either a Valved or Non Valved muffler. 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.

Each system is available with your choice of either chrome, black chrome, carbon fiber, burnt titanium or matte titanium clamp-on, "pivoting" exhaust tips that accentuate this expertly assembled exhaust system with a perfect finish. With clamps securing each tube in position and allowing multiple degrees of rotation in combination with our ECS Swivel Exhaust Tips, you have the ability to fine-tune the location of each component.

When paired with our standards of quality and design requirements here at ECS Tuning, we can provide your B5 S4 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.
