The 2011 997 GT2RS, with its 3.6L GT1-based engine produces plenty of power, however some believe it could use a kick in the pants as far as the exhaust note. Exotic it is not. In stock form, it is extremely quiet and vacuum-cleaner-like. This is where your friends at Shark Werks come in with our replacement exhaust system (only for GT2RS models).
Made entirely of T304 0.065 stainless steel, mandrel bent to fit to the factory catalytic converters, our system not only unleashes a more sporty sound (you can hear those turbos spool) but it does so with minimal additional noise inside the vehicle. You can continue to enjoy your phone conversations or tunes without interference from the exhaust. Meanwhile, your 997 GT2 or GT2RS produces a deeper, throatier growl from the engine at the press of the gas pedal.
Our straight-through design improves upon the factory titanium stock center muffler, which has no separation of exhaust gas pulses (as you can see from the hot spot in the middle of your factory unit if you examine it from outside). Our approach was to take the path of least resistance; to improve flow and reduce back pressure (all important for spool and power on a turbo car) by separating each of the banks with one exit for each side versus a more restrictive merge.
By retaining the factory cats, there are no check engine lights and the use of our exhaust should not affect the factory warranty or affect emissions equipment. Designed to work with factory exhaust tips, installation is made easy by re-using the factory clamps and locations.
