• Porsche 911 GT3 RS 4.0 gets a boost from Akrapovic

Akrapovic is widely known for attaching their exhaust systems to some of the nicest cars on the market. Vehicles such as the Ferrari 458 Italia and the Mitsubishi Evo X have all received this treatment. Now, with its 500 HP naturally aspired engine, the 2011 Porsche 911 GT3 RS 4.0 is one of the most impressive cars available on the market, but Akrapovic have provided what we are going to call a tuning detail to further tweak its performance.

Akrapovic actually has five different exhaust systems which will increase the engine’s output by up to 17 HP, depending on the version chosen. The first system is an Evolution exhaust system that will add 12 HP and 10 lb-ft. Then there is the Evolution Race which will add 17 HP and 16 lb-ft of torque. The Sports cup version will add 8 HP and 11 lbs-ft and the Slip-On exhaust system will add 4 HP and 2 lbs-ft. Finally, there is the Slip-On Race version that adds more horsepower and torque, although those numbers are not specified. All of these systems will include titanium link pipes with exhaust valves and a titanium end muffler.

Apparently, the beetle is small compare to this one, but they are the same in exterior designs. By the way, its good that they make some upgrades because the performance is not that impressive.

At first, the design looks kinda’ odd because it looks the same as the Beetle. Porsche 911 really has a lot of versions to offer now.

This version already have an impressive performance and I think Akrapovic tune up version is not that impressive! I really love the speed of the car. I wonder on what else the Porsche have to offer?

Well, I really don’t think that the Akrapovic made an extensive tuned up for this car. I believe that the car has an sporty look already as well as high speed performance. However, the 17 hp boost in the power output of the car is kind of impressive.
