Kenworth T800 project.. am I dead in the water?

Good advice right there. Even up here in Canada they are now saying brace for the next two years to be very bad. Elections and low oil prices kill the economy. Lots of highway jobs that were set for this upcoming summer are already getting cancelled by the government.

Put your straight pipes on, a couple light bars where the breathers would be and call it done. And enjoy the cheaper and easier air filter maintenance.
