Product Details

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

Enjoy your B8 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 and control your sound with our valved muffler design.

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. With the valves open, we showed gains of 19 WHP and 16 WTQ on our B8 S4 equipped with a Kohlefaser Luft-Technik intake and a stage 2 tune with pulley!

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. To open the exhaust, simply pressing the "valve open" button on the remote key fob unleashes a straight-through, raw, unedited exhaust symphony. 

Each system is available with your choice of either chrome or black chrome, 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 B8 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.

Though our exhaust comes with a remote to operate the valves, for seamless integration, the valve controller can be programmed to your HomeLink opener system. Following the instructions in your owner's manual, you will need to use the remote that is provided with the exhaust to program two unused buttons on your opener system. One button needs programming to the valve open button on the fob and the other will be programmed to the valve closed button on the fob. Now you can just store the remote away in case you need to reset the programming!
