It sucks cause I thought it would be closer than that cause I walked a 96 model before pretty good but I guess the newer ones are alot stronger. I don't think it was stock cause it was really loud and I don't think it would be that loud from the factory. My car has straight 3" exhaust all the way back and the Viper was way louder than mine was. Anyone ever seen a 09 Viper run the 1/4th what are they getting stock?
