I already talked to Rip. He can't help. I am trying to do a direct replacement of my current system, which is a one of a kind, with larger pipe, so he said he would need to have the truck on hand.
I have a flatbed, and I have a "y" in the pipe and the tips are in front of both tires.
The biggest pipe that fits on a first gen is 4", but once the pipe y's out to either side of the truck, I want to switch to 5" to the tips.
