The Tubi Style replacement muffler for the Cayenne Turbo is a slightly updated version of the previous years' model, with only a few minor changes, mostly cosmetic. It features a far less restrictive design that allows quicker spooling of the turbochargers and reduced backpressure, creating 10+hp gains at the wheels. This system not only has impressive aesthetics and power gains, but produces a deep growl combined with an aggressive tone that allows it to be completely drivable and simply amazing.
