That's one of the reasons I went with the 50 series. They sounded great from the tailpipes, but had horrible drone in the cab. That's the last set of Flowmasters I've bought. My 05 had a Flowmaster on it, but it got swapped out for a Magnaflow also.

Some like it loud, some like it subtle... you gotta figure out which team you are on!
Im with you on this one. My dual 40's on my 78 are under the bed and out the tail. My 50 on my 98 is under the cab and immediately dumps down, no exit outside the truck/totally hidden setup. The 40's are at least twice as loud with bad interior drone while the 50 is quiet as an aftermarket muffler gets IMO.

Re: Best sounding mufflers

i plan to try the summit branded magnaflows, I get a bit of low rpm drone with my super 40's w/ x-pipe, dumped before the axle.

Straight pipes. The most beautiful and last thing you’ll ever hear. 😂
