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.[...]
