Who makes a quiet yet small muffler?

[Jayschevy]

I have a bagged LWB 71 with a 350 motor in it with headers. I'm in the process of redoing some things like my rear suspension and converting from a LWB to a SWB truck. Space will now be very limited in the rear of my truck due to having to mount air tanks and compressors.
Because of this, I need suggestions for a quiet yet very small (length & width) muffler that I can mount in the area under the cab.
Again, I'm looking for something small and quite that'll not wake up the neighbors.
Any suggestions would be very helpful. Thanks

Small and quiet pretty much mutually exclusive... The smallest I've found are the Jones Turbo Tubes. Look and install like glasspacks but Turbo muffler style.

I have a set on my '79 CJ-5 mounted underneath the doors with fenderwell headers. I have about a 6" tailpipe, but they are reasonably quiet until you get on it. If you run any tailpipe that should help a bunch.

Can you not mount under the doors?
I don't like it, but it's an option.

Or how about an import muffler? lol

Any other suggestion for a small and not so loud muffler?
