Truckasaurus,
are you refering the the SS exhaust and muffler for the dual Fenton manifold?
If so, did they tell you it might not be until next year for availability? Maybe never...
If never, has anyone found any other source for a pre-fabed routing of even aluminized steel?
I would then most likely go with a FlowMaster Delta 50 or something like that to eliminate in-cab resonance.
