2.5 class allow aftermarket headers??

Up where I am, we have to have Manifolds can't run headers

How far up are you though??

 

[derek06]

Is it a 2.5 stock appearing workstock class or just a regular 2.5 nadm style class?

 

[Brassfield]

Together....... That's how both organizations are written up, hoping to get enough 2.5 trucks going so we can have a 2.5 by itself later on

But they have different rules for the 2 class' I would say 2.5 yes headers would be a go workstock I would think no. Only because 2.5 allows big turbos with 2.5 inducers and engine swaps where workstock is all stock appearing
