I have an 06 ctd with a straight pipe. Tonight i raced a guy with a second Gen and i had a hard time pulling him we were pretty much neck and neck the whole time. When we got to a light he said that all he had done was a straight pipe. How is this possible? He has what like 250 HP maybe at the crank and something like 460 torque i think that i should have walked all over him if he was stock. What gives?
