Just got this system in, so we figured you guys might like some close-ups. This is speedART's Powerkit for the Panamera Turbo w/Soundswitch, which includes: 1 high-flow air filter, 2 downpipes w/200 cell high-flow sport cats, 76mm (3") dual center pipes w/pre-silencer, 2 sport mufflers with Soundswitch capability, and 4 100mm (4") tips with the speedART logo. Output rises to 520 hp and 538 lb-ft of torque without touching the software.

Here's speedART's official pic:


And here are the detail shots of the exhaust:
