Porsche Carrera GT is now counts as a collectible item with prices over a million dollar apiece, so if you own one you probably want to keep it intact! But if for some reason you think this future classic needs a power upgrade, Kubatech is here to help. They fiddle with the car’s electronics and install a Cargraphic sport exhaust system. These changes will give an extra 48 bhp.

So the good old GT will put out 660 bhp instead of the factory-standard 612. It also makes 642 Nm of torque instead of the standard’s 590. That will increase its top speed by 13 km/h, up to over 330 km/h.

The price of this package is 10,699 Euro including the exhaust system. Not worth it!
