Porsche (997)911 GT2/RS (2007-2012)


The most sportive model offered by Porsche is the GT2. This car exhibits Porsche’s advanced technology, which is demonstrated in its ceramic composite brakes, maximum engine power with twin turbines and variable turbine geometry, but mainly, in its uncompromising lightweight components. The 997 GT2 is the first Porsche and also the first serial car which is originally equipped with a titanium exhaust system.


Akrapovic Upgrade Kit 1 for the Porsche 911 GT2/GT2 RS (997)
MFG PN S-PO997GT2-400
MSRP - $7995.00


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.



Feature Benefit Summary:
- Titanium header set
- Titanium link pipe set with integrated 400 cpsi high-flow catalysts
- Plus 19 HP (at 5,700 rpm)
- Plus 43 Nm / 32 lbs-ft of torque (at 3,250 rpm)
- 2 kg / 5 lbs. lighter than stock


Akrapovic Slip-On exhaust system for the Porsche 911 GT2 (997)
MFG PN S-PO997GT2SO2
MSRP - $9295.00



Because of comfort, durability and strict noise requirements regarding the exhaust system, some kind of compromise had to be made. This was reason enough for us to develop a real “sport-exhaust version” for this super sports car. Our requirements were very simple: lighter, more powerful and better sounding exhaust system. Two hiflow 100 cpsi metallic cats, larger tube diameters, measuring not 55, but 60 mm and reduced the power-consuming backpressure. This resulted in a power increase of 8 HP, a torque increase of 68 Nm and weight savings of 2 kg, compared to the stock system.



Feature Benefit Summary:
- titanium link pipes with integrated 100 cpsi catalysts
- titanium central muffler
- titanium tail pipes
- plus 38 HP (at 3.940 rpm)
- plus 68 Nm (at 3.900 rpm)
- minus 2 kg


Akrapovic Evolution exhaust system for the Porsche 911 GT2 (997)
MFG PN S-PO997GT2E/1
MSRP - $10200.00


Building on the modular theme, the Evolution system adds performance headers to the standard slip on system for additional performance gains. Two hiflow 100 cpsi metallic cats, larger tube diameters, measuring not 55, but 60 mm, reduced the power-consuming backpressure by more than 50 %. This resulted in a power increase of 41 HP, a torque increase of 74 Nm and weight savings of 5 kg, compared to the stock system.



Feature Benefit Summary:
- titanium header set
- titanium link pipes with integrated 100 cpsi catalysts
- titanium central muffler
- titanium tail pipes
- plus 41 HP (at 4.080 rpm)
- plus 74 Nm (at 4.020 rpm)
- minus 5 kg


Porsche (997.1) 911 GT3/RS (2007-2009)



Akrapovic Slip-On exhaust system for Porsche 911 GT3/RS (997.1)
MFG PN MTP-PO997GT3H
MSRP - $5220.00


A Porsche 911 GT3/RS (997.1) that is equipped with an Akrapovič Slip-On exhaust system is more powerful and lighter, even though the exhaust system is not replaced in its entirety. The sound of its six valve engine is also noticeably improved. A look at the numbers reveals that the Slip-On offers a 2 kg weight reduction in the rear of the Porsche 911 GT3/RS of and a 4 HP and 3 Nm increase in power. The reduced weight provides better steerability and the increased power additionally spices up sports driving, because the changes offer better lap times. Two tail pipes, measuring a 100 millimeters in diameter, make it clear that the Akrapovič Slip-On system is no ordinary exhaust.

Feature Benefit Summary:
- titanium end muffler
- titanium tail pipes
- plus 4 HP (at 7.390 rpm)
- plus 3 Nm (at 6.040 rpm)
- minus 2 kg



Akrapovic Sports Cup exhaust system for the Porsche 911 GT3/RS (997.1)
MFG PN S-PO997GT3CUP
MSRP - $6295.00


The Akrapovič aftermarket Sports Cup exhaust system is based on the Porsche Sports Cup rules, which means retaining the original exhaust manifold with integrated catalysts. We therefore developed a performance and weight optimized titanium end muffler with appropriate link pipes as the connecting piece to the manifold. This kind of construction reduces the weight by almost 21 kg in comparison to the original exhaust system.



The weight distribution of the vehicle is improved considerably, because of the weight reduction in the area behind the engine and the rear axle, which has a extremely positive effect on the handling. The limit range of the vehicle adjusts upwards and so a higher transverse acceleration is possible. The combination of improved power to weight ratio (through an increased efficiency of over 8 HP), torque progression by over 16 Nm, and the positive effects in connection with driving dynamics enhance the performance of the GT3 distinctively. The sound in this configuration is somewhat below the sound of the original system with the opened exhaust cap.



Feature Benefit Summary:
- titanium link pipes
- titanium end muffler
- titanium tail pipes
- plus 8 HP (at 3.970 rpm)
- plus 16 Nm (at 4.060 rpm)
- minus 21 kg



Akrapovic Evolution exhaust system for the Porsche 911 GT3/RS (997.1)
MFG PN S-PO997GT3E
MSRP - $12795.00


The Akrapovič Evolution aftermarket exhaust system is based on the same layout as the original exhaust system of the GT3 with valve control. A newly developed exhaust manifold with 100 cpsi sports catalysts guarantees an increase in power and torque, as do the newly developed and optimized pre mufflers. But the real plus of this exhaust system is the weight reduction of 17 kg, while it maintains the original layout and functionality of the exhaust caps.



The weight distribution of the vehicle is improved considerably, because of that weight reduction in the area behind the engine and the rear axle, which has a positive effect on the handling. The limit range of the vehicle adjusts upwards and so a higher transverse acceleration is possible. The combination of improved power to weight ratio (through an increased efficiency of 12 HP), torque progression by 14 Nm, and the positive effects in connection with driving dynamics enhance the performance of the GT3 distinctively. The sound impression in this configuration is somewhat more voluminous and with opened caps way more aggressive than in the original version.



Feature Benefit Summary:
- titanium sports manifold system with integrated 100 cpsi catalysts
- titanium pre mufflers
- titanium link pipes with exhaust valves
- titanium end muffler
- titanium tail pipes
- plus 12 HP (at 5.510 rpm)
- plus 14 Nm (at 5.740 rpm)
- minus 17 kg
