Enjoy your B9 A4 with the most engaging, race-inspired, performance cat back 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 in-house designed and engineered ECS Cat back exhaust system. In normal, comfortable driving conditions, the in-house designed resonator prevents drone but when you put the pedal down you get to hear the unedited exhaust symphony all the way up to redline!

The full cat back 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 large 3" non restricted pipe into the center resonator for more refined sound and exits though our in house designed mufflers for an aggressive enthusiast sound that we all love. 

Our system is available with your choice of either chrome, black chrome, carbon fiber, titanium and burnt titanium clamp-on, "pivoting" exhaust tips that accentuate this expertly assembled exhaust system with a perfect finish. Our exhaust tips secure each tube in position and allow multiple degrees of rotation in combination so 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 B9 A4 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 with the supplied stock and aftermarket downpipe adapters. 

Our ECS Exhaust System was designed, engineered, tested and quality inspected by our Research and Development team at 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 printers, and rigorous long term product testing.
