Here’s something to get you through the weekend. Well, not that much of it left, but anyway, here’s an awesome video of an awesome car tuned by an awesome tuner! We’re talking about a RENNtech Mercedes SLS AMG revving and accelerating around, scaring the local wildlife to death with its noise. They’ve fitted it with performance exhaust featuring secondary catalytic bypass and x-pipe and a tweaked ECU. Now, the standard SLS has a very sweet soundtrack, but this one’s just off the hook! Crank up your speakers and enjoy.
