Product Details

         True automotive passion can come in many varieties. For us, we've found driving euphoria with our ECS Valved Exhaust System. 

Embrace your automotive driving passion 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 true driving passion with our ECS Valved Exhaust System and control your driving experience with our valved muffler design.

Included with our Valved Cat-Back System is an OE-downpipe adapter that mates to the T304 stainless steel, 3.0" mandrel bent system. Exhaust gases are channeled from the OEM downpipe and then into the dual inlet muffler where 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 normally open channel of the muffler, where sound reduction takes place. Controlling exhaust reflection within the normally open channel of the muffler is accomplished via three perforated tubes with directionally louvered openings for improved exhaust flow and sound control. 

To quench your passion for shear driving pleasure, simply pressing the "valve open" button on the remote key fob unleashes a straight-through, raw, unedited exhaust symphony. When the pneumatically actuated exhaust valve opens, exhaust gases are channeled directly through the valved section of the muffler for an unrestricted, 3.0" passageway.

Each system is available with your choice of either chrome or black chrome, clamp-on, "PIVOTING" exhaust tips that accentuate to the pinnacle to this expertly assembled exhaust system. One of the many features of our system is the ability to infinitely adjust its fitment to your utmost visual pleasure. With Accu-seal 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 humbly provide to you a perfect blend of performance matched with interactive driving pleasure. 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 with a true and honest, perfect fitment guarantee.

Designed and manufactured in Northeast Ohio, our Valved Exhaust System utilizes only premium materials and world-class manufacturing techniques to deliver unmatched quality and reliability.
