I raced a boy in my towns Chevy SS b4 i got my wheels. He had dual flowmaster exhausts, and mine was stock. Raced, and off the line i would get him, then he would start catching me, and it was back nd forth, nd we would be even and then about 85 I would Run off and leave him, as he would start bogging. Now he has a CAI, and I can still beat him, not as bad, but by a couple of truck lengths. Hes soon gooing to get a chip.. I havent raced him since ive got exhausts. He will prolly leave me when he gets a chip. Ive also raced numerous trucks, who when i go to pass them try to floor it, to keep me from passing them, and I jus blow right by them.. You can tell it pisses them off too.Im extremely happy with my titan.
