Roothy's red truck (the 45) has a 350 in it. He has got rid of the stack & now has twin pipes exiting out the back.
any pics of 40 series running tall exhaust stacks for water fording?

Did he get rid of the stack because it wasn't working with the V8 (back pressure problems or otherwise)?

Good to know.
Nice work Roberto. Got any sound clips? I have never seen a stack exhaust other than those giant obnoxious ones on big diesel pickups. I feel like hearing exhaust from above my head would be odd (and cool).
Met with my exhaust guy yesterday and looks like the whole set-up is gonna be between $800-$1k. 
That's about what I was expecting. My bumper will be on in a week or so and then I'll start on the exhaust.

Its actually quiet, I dont have any sound video, not that tech savvy yet. I can tell you that prior to this exhaust setup I had it exiting right before right side rear tire and was sooo loud, then I exited after the tire and was better, so with the crossing over to other side and then up 4 feet it is quieter yet..

We finally got our exhaust done complete with a stack. We will likely only run the actual stack when it's needed since its not hard to install it. We also went with 2.5 S.S.

Connector for the stack before all the welding was done.
Love the sound and there seems to be plenty of flow even with the stack on.

Pics of the final product?

Well I haven't made a strap/bracket to hold the stack in place while in use but here's a couple other angles in the shop. For those who might wonder yes I realize the stack can be a big hang up but there wasn't any other way to run it.
Here's the pipe exit...directly behind the rear tire and just above the frame.

Wouldn't the exhaust positive pressure be sufficient to force the exhaust
gas out even if was exiting underwater? Is it necessary to install a tall
exhaust?

Ahhhh... the age old question: To run a stack or Not too.
I believe in most circumstances it is sufficient without one. For me it's about I'd rather have it and not need it than not have it it and need it. I believe mostly it's a personal decision.

Looks good, I keep my mounted on rear but dont have it hooked up so I just run my small exhaust out rear side for it as well is easy to just take the connecting piece out that connects to stack.

I never knew Milo had an exhaust stack. Must not have looked hard enough. I'm thinking of putting stacks on my hj47 as my dad could probably source one for cheap

I don't think red has a stack. I could be wrong. I remember roothy quoted during a river crossing that they sound like motor boats in the Port Macquarie DVD and I think it showed a normal exhaust but it could of been another Cruiser. Forgot if it was Red

Here's an interesting thread showing a Dodge M37 miltary pickup with a fording system. The exhaust stack is designed to be stowed when not needed. There are mounts on the bed side to hold it horizontally when not in use.
There is also a post in that thread about backpressure and the effects of restricting the intake and exhaust. Myself, I only see that as an issue if the intake and exhaust are not designed taking reduced flow into consideration.
