I've got a 934a2 and I'm thinking about putting a 5 inch exhaust on it taking it up above the box has anyone done that without a muffler.
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
.But 5” looks so good
.My muffler was rusted out so i straight piped it. Operating the crane though is a bit loud w/o ear protection.
I also went with 4”, simply bc that is what factory was and that is what the local exhaust shop had in stock.
Sounds better but i wast going for sound, i just didnt want to buy a new muffler.

Say what? I can't hear you!!
.I'm hoping that it will be quieter if it exhaust up above the box it will be loud outside but maybe not so loud inside. My girl that we were going to have to wear headsets like an airplane forever driving it so she was tickled it you don't have to do that.
.Great idea I'll do that, I planned on Dyna matt the entire cab and fire wall The cab has like army green foam almost the thickness of like a sleeping pad stuck on it I'll be taking that off. I'm sure it was better than nothing
hushmat is much cheaper than dynamat. I used a product called lizardskin spray on sound dampener. It reduced interior temps by at least 15° and cuts down on a lot of the racket. I too installed a 5" straight stack and should've went to a 60" to get the sound above the cab. Its annoying loud unlike my tweaked 3406bGreat idea I'll do that, I planned on Dyna matt the entire cab and fire wall The cab has like army green foam almost the thickness of like a sleeping pad stuck on it I'll be taking that off.

Iv seen several youtube vids on that lizard skin and saw the db meter measurements, but of course that stuff could have been manipulated. Its good to hear about it from an outside user source.hushmat is much cheaper than dynamat. I used a product called lizardskin spray on sound dampener.

We use it a lot in our street rod,muscle car builds. I can promise you that it works. I have it in a 63 falcon and it has a.c. and before the lizardskin was sprayed inside and underside it worked ok or so so. After spraying it on just 3-5 mins of a.c. running it will frost the Windows up in 85-95° temps lmao. I have to turn it down to fan speed 1 and turn vent. Crazy how quiet it is inside as well no road noise Heck can hardly hear another vehicle coming up beside me. But emergency sirens or vehicle horns you can still hear very well.Iv seen several youtube vids on that lizard skin and saw the db meter measurements, but of course that stuff could have been manipulated.
