As per NMRA's rules state, in order for the 2011 5.0 4V to run in the Factory Stock class, they have to either run the factory manifolds or a 1 5/8" long tube header.
Well, we have the longtube headers here in stock for those of you that are trying to run in this class.
We have the 1 5/8" longtubes into a 3" collector including the 3" off road x-pipe with a step down to 2 3/4" to be able to run the required 2 3/4" catback on these cars.
These are in stock and can ship today.
