Your right, there are no emissions up here. Never has been, and no one would likely care. However I do have ambitions to eventually move farther south, where this type of thing would come into effect. I know the truck is an 86, and installing a newer engine may change the requirements, but I figure it'll be less hassle if its properly installed already, rather than arguing when it has to be done.

Glad to hear the truck manifolds fit. I don't mind frame notching. If the manifolds fit, then the y pipe should as well I'm assuming. Thanks for the input.
