How to pick a muffler

So I am looking at these mufflers does the length of it affect the noise, or what?

Any info it appreciated.

Assuming you've got a delete pipe installed and want it quieter?

Usually longer length will make it quiter

Does anyone have a opinion on a 5" inlet/outlet muffler for my 6.7?

08powerstroke6.4, can you post a video of your setup? I haven't heard a aero turbine muffler yet. Does it get rid of that weird sucking noise when you let off the throttle? Thanks in advance

OK I got a Donaldson muffler. It is very heavy. Did you add any extra support for the muffler when you installed?
