The 991 Turbo S came to Turn3 Autosport for a full service and the installation of a Sharkwerks exhaust. The 991 Turbo S has amazing performance but needs a little more exhaust note. Not only does the Sharkwerks exhaust provide the needed change in sound, but adds additional performance as well. The Sharkwerks products are top notch and fit extremely well. Contact us for more info on purchasing Sharkwerks products and having them installed.
