Muffler question

I have a 2012 with full delete. I have been running around with a straight pipe for a few years now but would like to quiet it down. Any suggestions for a muffler to do the job? Links to your suggestions would be appreciated.

I believe Flo-Pro makes a muffler as one was offered to me, but I chose the straight pipe too.

I put on a Donaldson and did a review. I love it, it's extremely quiet in the cab.

I’ve been running the muffler that came with the 4” flo-pro, but when pulling the camper through the mountains it kind of drones, so I’m contemplating swapping out for the Donaldson.

You didn't mention what size exhaust you have, but I just installed a 51" Donaldson on my truck with a 5" straight pipe.

I went with both a Donaldson and fte aerator up front. It is almost as quiet as with stock exhaust, cab is no drone, absolutely love it.
