We have always admired the sheer viciousness of the Porsche 997 GT2 RS as a serious sports car designed as a ruthless speed machine – one that takes no prisoners. But we always thought the car doesn’t sound as angry as befits its character. Now, on the evidence of what you are about to see, that issue can be addressed by nothing more sophisticated than some straight pipes!

Be careful though, because straight-piping the exhaust system on your Porsche 997 GT2 RS can result in it sounding like a tractor while idling, and making a racket akin to that of a World War I plane.
