Just so you are aware, Grand Rock does not make a 5" down pipe for the Dodges (yet I'm workin' on getting them to start building them) so technicaly these kits will be 4" to the y-pipe, then they turn to 5". The stacks reduce to 5" o.d. and fit in the i.d. end of the y-pipes. We do make a universal stack kit with a 5" inlet under the truck, if you have 5" exhaust already under your truck.
