Quiet Muffler Help
Has anyone heard of a muffler with a 4" inlet and outlet that isn't loud as hell. I have a dual 3" inlet to single 4" outlet magnaflow muffler and it is too loud for my taste.
I found an MBRP "Quiet" muffler that is 4" inlet/outlet but I know they make diesel exhaust. Would a diesel muffler be different than a gas muffler? And would it quiet my exhaust down from a magnaflow? Thanks

Your dual 3" inlet / single 4" outlet Magnaflow doesn't have a lot of room for sound absorbing packing, that's why it's loud.
Do you have room to add another muffler after your current Magnaflow? Would a 7" dia Magnaflow with a 14", 20", 24" or 30" case length fit?

IMO, don't reduce the outlet size down to a single 3", that'll reduce flow/power.
I'd just replace the muffler with a dual 3" inlet/4" outlet Y-merger. Then run the longest 7" diameter 4" in/out round Magnaflow muffler you can fit .
