BillBoost37 is a glorious beacon of light

There'* so little that can be done to a rear manifold.. the only reason to get it would be that it'* painted the same.

There is actually a lot of work done to the ported manifolds, they are welded on the outside and grinded on the inside. There is a solid hour spent grinding on just the rear manifold(with good equipment).
