4wd long tube exhaust routing

[wasted wages]

So I have searched and haven't came up with an answer to my question yet. This said here's what Im hoping someone here can help me with. I have a 89 k3500 that I'm basically doing a full restoration on. I have the truck back together and running and now it's time to do the exhaust I have 100% done all the work so far an want to keep it that way. This means doing the exhaust here at home as well. How have you folks ran your exhaust systems with a similar setup? The truck has a turbo400 and np241 case. I'd like to have dual pipes.

The first step is getting the long tube headers bolted in place and then you can plan where the pipes will need to go.

I crossed mine over at the back of the transfer case.

Thats what I was thinking Id have to have to do when I was looking under the truck this evening.

I crossed mine over under the trans pan, I made that section easy to remove and wrapped it in head tape. Then ran into a 2 x 2.5" in/ 1 x 3 " out Flowmaster and exited in front of the rear tire.

I'll try and fit my pipe that way again just to see but, Im almost positive with the headman headers the pipe will hit the pan I'm running.

Looking at those pics actually helps me a ton. Im 95% positive I have enough exhaust pieces to build a crossover like that and clear my pan now that I think about it.

Here’s how my Yukon is done.

Unfortunately, I didn't have the gap between the trans pan and cross member as that would be the way to go.
