We have XM818 with 250 Cummins and M55A2 with Continental LDS 465 converted to fire trucks. We got rid of the under hood muffler on the XM818 running pipe behind the cab to a heavy duty regular truck muffler with extension that helped some on heat issues in summer and noise but they are both still noisy. You can add better mufflers like that and insulate the firewall and cabs with insulation and foam padding with insulation and rubber matting on floors like the later M35A3 and others have. We just got a M35A3 2.5 T and it is amazing how much quieter it is.

And I still wear muffs in my A3 because I think it's too loud!

Quiet at idle though, very quiet.

First time after running the pipe behind the cab on our 5 ton with the 250 Cummins I put a straight chrome pipe on it but got over that fast we couldn't hear our radio or talk so a muffler went on.

Our 1997 A3 seems like a Cadillac to us after driving the 5 tons. We are seriously considering putting some insulation in our 5 tons like is in tractor and construction machinery. DB Engineering makes it.

Cab Insulation

Type of top also matters hard tops are much quieter than rag tops m818 had a hard top and really wasn't bad still wore ear plugs my 813a1 has a rag top and is much louder ear plugs are a must believe it or not its mainly the fan which causes all the noise rolling down the highway.
