My brother has a 1998 c5 vette with new exhaust and headers along with some sort of air intake that replaces the stock fog lights. It's pretty fast. He dynod at 341rwhp, but it would smoke my supra when it was making 350 rwhp. It's totally different riding in his car. It feels like it has 700rwhp. I outrun him everytime on the highway, but I wouldn't say it's not fast. From a dead stop he rapes me. His is an automatic and it will pin your head to the back of the seat. I dont think some of the people here know how fast they really are. Again, a modded supra will own a vette, but you had better have at least 13 psi or you'll get your ass handed to you imo.
