Back in the early days Darrell Waltrip was racing modifieds. He was getting beat week in and week out by this one team’s cars. Darrell called them skeeter cars cause they buzzed by so quick all he could hear was the buzzing sound they made. This team’s car looked like theirs and they could never figure out what those guys were doing to beat them so bad every week. They just knew those guys were cheating on the engines somehow.
Well, they hatched a plan. Darrell decided to buy one of the old cars from this team. They were thinking they could tear the engine apart, figure out where they were getting beat and use that to beat those guys. Well, they tore the engine apart & found nothing out of the ordinary. What they did find though was that the roll cages were made out of exhaust pipe and not the mandatory pipe. The exhaust pipe was hundreds of pounds lighter. So they thought they were getting beat by a cheater who souped up his engine & it was because the other car weighed hundreds of pounds less!
