For sale, less than 5,000 miles since installed, Eisenmann RACE exhaust with 83mm tips with Supersprint X-Pipes.
This is the real deal, the same as the Kellners Exhaust (except no Kellners on the tips).
Current price for this Eisenmann exhaust is $2403.56 plus shipping. This has the updated tips (with the perferated internal tip design). These are generally not in stock, and there is a 3-4 week wait to get these.
