How to make it quieter?

Has anyone changed the exhaust system to make it quieter? After adding the top, doors, wind shield, etc., I have a big problem with the noise of the motor.

You are right it is noisy, after all day out my ears are tired . I think it's just a symptom of a large single cylinder motor.

Koplin, Flowmaster and several others have started making aftermarket secondary exhaust that you add after the stock exhaust that cuts noise by 50%.

YES, go to a plumbing store, Lowes & Home Depot will not have, get a One inch 45', or street L it is called. copper
Get a Reducer 1 1/2 x 1 copper
Get a piece of 1 1/2" copper tube
connect the three to muffler, use a U clamp to hold pipe to frame.
This extends exhaust & noise out past end of Big Red. No longer need ear muffs

NOW, how do you reduce, stop, the wind, dust, dirt, cold, etc. coming up between the back of seat & dump bed hitting the back of your neck/head WITHOUT going to a Full cab enclosure ?

The 1 1/2" copper piping as explained before, extends the exhaust & exhaust noise out past the bed...... works as good as Koplin, Flowmaster at about 1/5 the price.
I've heard people not happy with the results of Koplin, Flowmaster...

Engine noise is another matter ...... insulation, insulation as the plastic body make it like a drum
