I have a brand new Kline inconel super alloy valvetronic exhaust system for the Audi R8 V8, pre-facelift (gen 1.5) which is from 2009-2012. Doesn't fit the newer rear bumper. It's never been installed, comes with a certificate of authenticity and the Kline book. Lighter than a comparable titanium exhaust system yet stronger and more heat resistant. Truly cool stuff and the sound is the best there is. Zero drone. New, these are over $7K. Asking $4500 shipped in the Continental U.S. Thanks for looking and PM me with any questions.
