    $600 ECS Stainless Cat Back Valved & Resonated Exhaust Black Tips, C7.5 A6/A7

    Original price was $1,850, I am selling for $600. The price is right because I want it gone. It's in perfect shape. I am selling this for CASH and LOCAL pickup only. Located in Peachtree City, Georgia 30276. The exhaust was professionally installed and then professionally removed by GMP Performance in Peachtree City, Georgia, and the exhaust has <50 miles on it. It's effectively new. I am selling because the noise was interfering with marital bliss. You can see in the pictures that I did do a fiberglass wrap on the mufflers in a desperate attempt to reduce the decibels but it wasn't enough. Those can be easily removed. Setup includes optional mid resonator and smaller sized black tips. Please note that the Billet Boost Tap Kit is NOT included but can be purchased from ECS for $47. Everything else is included just as shipped from ECS. ECS provides a lifetime warranty.

    Enjoy your C7.5 A6/A7 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 allows for MMI control and operation of the valves. 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. 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. Once the exhaust valved are opened it unleashes a straight-through, raw, unedited exhaust symphony. Each system is available with your choice of either chrome, black chrome, carbon fiber, burnt titanium or matte titanium 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 C7 A6/A7 a perfect blend of performance and an interactive driving experience.

    The title is for a C7.5, but the product description says C7. Does this work with a C7 A6 if I also get a rear diffuser designed for quad tip or is there something else about the C7.5 that makes this incompatible?

    This is definitely the ECS model specific to the C7.5 facelift, not C7 pre facelift. To be sure about fitment, I would recommend you call ECS on Monday. My general understanding is that the mounting points, layout and diameters are identical but the length of rear muffler section is different because of the bumper cover redesign. I would imagine that a qualified shop would make it all work, but unfortunately I can't say definitively that it would fit without modification.
