Stopped by the muffler shop today and had the front pipe adjusted. I'll spare you the details but basically once I got it home I needed to add length to the vertical section that drops down from the manifold. So the final fitment is excellent but the front pipe has two flared sections. Of course I'd rather have it as all one piece. I will verify the final fitment and then weld the segments of the front pipe. For now, I will be satisfied with a functional exhaust. Once I can legally drive the truck to the muffler shop, I'll have a new front pipe made.
The photos may not show it well, but the pipe is 7/8" below the lower frame rail flange and runs perfectly horizontal to the rail. All the other bends look great. I need to add a few support brackets and I need to study a few reference pics to make final adjustments to the position of the tail piece.
