extended snorkel style exhaust

Need info, anyone out there?

why would you need this, just keep the motor running.

all military vehicle have exhaust snorkels incase of an engine shut down while submersed.
I don't know what kind of crossings you do but mine have gotten pretty crazy at times.

With that said, I think you waould have to worry about every leak or hole in your exhaust first, then address the snorkle. I don't think many have done this mod. Be the first, if you do a great job everyone will want one, just make sure you paint it a pretty color.
