The 991 Turbo / S pumps out immense performance but in typical Porsche fashion the factory leaves a little bit on the table as far as a proper sports car sound is concerned. For a $150,000+ car, it could certainly use more of an exotic growl along with more of a turbo spool/whine that is customary with turbo cars of yesteryear. This is where your chums at Shark Werks come in with our replacement exhaust system for all 2014+ 991 and 991.2 Twin Turbo & Turbo S models.
