so here is the 2nd most recommended muffler to quite a diesel, a Donaldson muffler. now i went with a shorter version though since i don't quite have the room, so 20" body vs the 44" most ppl get for a ram. this is an M090595 with 5" in and out.
straight thru design, but then you can see the baffle right smack in the middle. i guess if it's too quite i can just start drilling holes in that.
the rear fenders are about 13" wide, and this can is 9" dia plus at least 1" off the bed side, so i'll still be at least 3" inside the fender lip with this side pipe. don't forget that i'm making the whole bed wider to get around the duals vs just wider fenders.
