I'm new to this site and the Forum so please excuse me if i breach some unknown protocol.
I have a 2010 Panamera Turbo that does not have the factory installed Sport Exhaust System. No one at the dealership can answer any questions about how to get the OEM system installed, or if the separate parts are even available. I have found several seemingly quality after market sport exhaust systems ( Hennessey, SpeedArt, Fabspeed, Akrapovic, Sharkwerks..etc) but before I buy one of those I was wondering if anyone knew anything about retro fitting a new Turbo with the factory Sport Exhaust system, or if any one had experence with the previously mentioned after market systems.

Thanks very much,
