As with any car, with a bad driver the Cobra can be beat. I ran 12.47@113.6 with x-pipe, flowmasters, and K&N filter (on street tires).
So for every good (or decent driver) there are probably 5 bad ones. I am not trying to flame anyone, just trying to help reinforce the point, that learning how to drive better could be one of the most important mods
