After a strong 4 year run, Porsche decided to update the Cayenne Turbo in the 2007 model year. A more powerful 4.8L twin turbocharged V8 and slightly updated exterior were the two main changes brought on by the facelift. The exhaust system remained relatively unchanged except for some minor differences in the outlets thanks to an updated rear valence. The Tubi Style system was largely successful on the pre-2007 model, so only minor updates to the outlets were needed in order to make it effective on the facelifted model. 7+kW gains are still achieved by adding the system, and it still produces the same aggressive growl Cayenne owners have come to love. Normally, Tubi prefers to redesign their systems for each new model, but in this case the changes were almost entirely cosmetic so it didn't make sense to reinvent the wheel, or in this case, the muffler.
