Good morning everyone i recently purchased a 2011 a8l and i am trying to find a cat back exhaust for it. Everywhere I searched does not carry anything to fit my year. Any insight or recommendations would be greatly appreciated.

There are a few out there but very expensive. If you search this forum you'll find them. A custom system from a reputable shop is your best bet unless the price isn't a concern.

Magnaflow

Assuming you have a 4.2, magnaflow is your best bet. And truth be told audi did an excellent job with intake and exhaust, your biggest bang for the buck is a tune on the 4.0 or 3.0. Tunes for the 4.2 don't gain much

MP4.2+6.0

+1. It is going to be for sound on a 4.2, not for any demonstrable power gains. Factory already tweaked it for literally 25 years and about about 5 design cycles, with D4 being the last and best they could do--for the passenger car flavor. RS5 and R8 were the other flavor, with different engine components and tune approach emphasizing peak HP more than torque.
