If you're looking for the lightest, loudest and most aggressive exhaust available for a 2007+ GT3 or GT3RS model (including 2010+ 3.8 and 4.0 models), we have a simple and affordable option: the Shark Werks Race Exhaust. This removes all mufflers for maximum high-RPM horsepower and exhaust flow.
The system is made from CNC mandrel-bent stainless steel and weighs only 8.5 pounds, removing nearly 60-pounds from the rear of a 2007-2008 model and about 50-pounds from a 2010+ model with the titanium center section. It is designed to use factory or aftermarket exhaust tips that fit the factory flange.
This item is manufactured in California, and is in stock and available for shipping today with domestic and international orders.
