The Panamera is the first four door sedan to ever make it to production for Porsche. This unique Porsche comes in three models, Panamera S, Panamera 4S and Panamera Turbo. The turbo model has AWD drive standard and is a front engine car.
From the factory, the Panamera Turbo has a tame exhaust tone. Kreissieg set out to change this by using the proven F1 Valvetronic system that allows the user to select the sound level. Designed to retain the OEM cats, the exhaust system is capable of reaching a much more race inspired exhaust note, that is a signature of Kreissieg, without throwing a check engine light. With dual 80mm high flow valves and included mid-pipe, the Porsche Panamera F1 VT Exhaust by Kreissieg is much less restrictive and provides a beastly sound fitting for this performance sedan.
