ECS Tuning Build Your Own Audi B8/8.5 S4 3.0T Valved Cat Back Exhaust System - Titanium

True automotive passion comes in many forms. For us, we found it in our Catback Back Exhaust System for the Audi B8/8.5 S4

Enjoy your B8/8.5 S4 with the most engaging, race-inspired, performance 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 Titanium Catback Exhaust System.

The full exhaust system is made from high quality brushed GR2 Titanium with TIG welded pie cuts for an exceptional look and durability. Exhaust gases are channeled through the in house designed downpipes, your choice of resonated or non resonated sections , integrated x-pipe, and then to the 3 chamber, in house designed mufflers. The perfect way to unleash hidden horsepower in a modern supercharged engine is to upgrade the restrictive factory catalytic converter and resonators with a smoother, higher flowing unit. This is a great way to increase performance and add a nice growl to the exhaust note.

The resonated downpipe arrangement gives a fantastic exhaust note without significant in cabin drone.

Each system is available with your choice of either chrome, carbon fiber, titanium 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 B8/8.5 S4 a perfect blend of performance and style. 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 Titanium Valved Catback 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 and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long term product testing.
