Once finished, Xecution caught the attention of Amir Rosenbaum and his crew of racers at Spectre Performance and was invited as a guest in their booth at the 2011 SEMA show. It was a showstopper to say the least, and easily garnered an invite to the Optima Ultimate Street Car Invitational where Filip drove it to an easy Ninth Place overall finish amid some very stiff competition. On top of all that, Xecution was awarded Best Domestic Car at the Ninth Annual Sony Computer Entertainment America (SCEA) Gran Turismo Awards.

To say the past couple of years have been a whirlwind of long hours and hard work for Filip and his fledgling company is an understatement, but it’s all beginning to pay off. CorteX Racing is getting on its feet, and Filip has never been happier. And all because he embraced his passion for hot rodding his ’66 Mustang and letting it take him where it led. We think all of us could use a bit more of that philosophy in life. Where could your hot rodding passion take you?
