I drove a 98 cobra, it was stock except x pipe and exhaust. I didn't like how it always sounded like you had your foot in its ass. They rev so freely and high, as well as thats were they make there power high in the rpm band. What I did like was shifting at 7000+rpm compared to my 2v 6000 rpm shifts. It spun the tires so hard from 1st to second. I definately know on a road course where you need to rev high those things have to be awesome. But with a stock gear, driving around in the city they can feel sluggish.
