When crafting the ECS exhaust systems, their primary focus is on achieving the perfect balance of sound and comfort.

There is something about a cat-back exhaust that is just so good. Being able to unbolt and replace the entire visible exhaust gives you butterflies in your stomach. A fresh new exhaust and just knowing that things are about to get rowdy. This exhaust features twin 2.5" brushed pipes with flanges that bolt directly to your factory and aftermarket down-pipes. The dual 2.5" mid-pipes make their way toward the rear axle and converge into a single 3" exhaust section. The 3" exhaust section snakes through the rear section of the car making smooth dips and curves to make its way into a light-weight 3" turbo style muffler. Don't be fooled by the 135 muffler, the size is nothing but deceiving. The turbo-style muffler features an inner design that refines the exhaust note to perfection. An extraordinary mixture of both tone and volume. Paired with the 3" muffler is your choice of 3.5" exhaust tips that give your rear diffuser a sporty look that shouts performance.
