Improving exhaust sound with dpf

Grass burner exhaust is just as quiet so I suspect nothing you can do legally.

 

Do them urea snort'n rigs even have mufflers anymore?
Or is all that after treatment junk enough to satisfy noise ordinance?

If you got mufflers toss em'. Might help some..

 

Good question. This is a weedburner dont mind the rolled over truck. .. I dont think any of those are mufflers but i could be wrong. I know one is the dpf

 

Great time to perform a grease job.

 

I tried to tell the dot officer it would be the easiest level 1 he ever did.. He didnt find that funny

 

I always liked pulling driveshafts on roll overs. Much simpler standing up.

 

The emissions system is the muffler. There's 3 (sometimes 4) catalysts that the exhaust has to flow through.

Really nothing you can do for the exhaust sound without doing some stuff that they don't like discussing here.

 

@jamespmack beat me too it.
