Well first off I don't race very much but one day my friend with his Viper 97 GTS said "he was going to leave me in the dust." Vetts don't have enough power. his mods (smooth tubes K&N No cats, no muffler, 1 inch lower) We were driving down a long country road He was in front. We went over a RR crossing and jumped on it. I was on his bumper hard then at around 140 he hit some dirt and stone so I backed off not to ruin my paint. The only thing he said was man your car is fast with a supercharger you would beat me. My cars mods are fresh air intake K&N, no mufflers, Bosh 4 plugs, 160 stat, Z06 rims and tires and 1 inch lower. Oh and the best part is he gets 21 MPG I get 35 - 40 MPG at 65 MPH and $20,000 less. his car is awsome but I love my vette.
