SD220 Muffler Recommendations?

Any recommendations on what muffler to run on my SD220? Something that sounds stock but not too loud or too quiet. Something basic.

This type is sort of like the stock set ups in the old trucks, they make many inlet outlet sizes.

This thread interests me too. Right now my truck has an old "Cherry Bomb" muffler on it and is a bit too loud.

I have a plain Jane 20" muffler on mine that the local exhaust shop put on for me back in the 90s.

Re: SD220 Muffler Recommendations?

I use any generic muffler that will fit the pipe and a spout on the back.

That works most of the time, but I got bit once, everything fit nice, and it was on a school bus with a 392 and Allison auto. I didn't pay close enough attention to the spec's, It fit alright but was only supposed to be a resonator. Bus was nice and quiet at low power, but once it got to speed... god awful racket! Even with the pipe all the way to rear bumper, I didn't know a 392 could make that much noise. I had to replace with a muffler, put the resonator further back on the system.
