For GT2 and GT2 RS owners looking for a power increase while maintaining the OEM titanium muffler.
The Akrapovič GT2 Upgrade Kit 1 consists of lightweight titanium headers with cast titanium flanges for a perfect, leak-free fit. In addition, the kit also includes a pair of high-flow sport catalysts (400 cpsi). These catalysts connect directly to the OEM titanium muffler without any alterations. The catalysts are designed such that no ECU reprogramming for GT2 (997) is required. The “Check Engine Light” will not be triggered with this installation at GT2 (997). The headers and high flow catalysts combined will deepen the exhaust tone, making the engine sound more aggressive. Furthermore, with the significant reduction in backpressure there is an increase in horsepower without any further modification being necessary. Gains of 19 horsepower and an amazing 43 Nm / 32 lbs-ft of torque will be realized with the installation of this kit alone. A 2 kg / 5 lbs. weight reduction is also achieved.
