I dont mind Flo Pro for diesels(had one on my Powerstroke) but i am not a fan of them for gassers. Are you looking for a lower cost system? If so we have some options from MBRP that are less expensive.
Was looking at something like the mufflex setup with a reso delete or a FM 50HD or a true dual setup...lol...

For you guys that have run the MF 12909 22" muffler, did you end up keeping the stock tailpipe? I have installed this muffler on one other 6.4 Hemi truck, and ended up having to cut the tailpipe. Looking to keep everything as much intact as I can, in case I dont like the drone. Just looking for advice on how you guys installed that muffler without modifying the tailpipe or inlet pipe.

Just installed 2 perforated tube packed mufflers in series and got almost stock sound. Granted, it’s probably Not the lightest setup and its not cheap, but its free flowing and just a slight rumble at startup and idle. Cruising at 2200 rpm there’s nothing to be heard over my Cooper ST Maxx tires. I even turned the radio off and still had to listen to hear it. And drone is nonexistent, even in eco mode. What it sounds like from the outside I cat tell you, but sitting still and revving it doesn’t produce much growl.

Put a 24” AFE in line with a 22” Magnaflow and tied into the factory tailpipe with the resonator intact. Only put 25 miles on it but did notice it moves up the RPM range s little easier without the stumbling I used to experience around 1800 rpm under light acceleration. Also showing a little over .6 mpg improvement on the evic. (Again only 25 miles so far). All in all, im pleased. Just thought I would drop my $.02 for the okd farts that want better flow without the excessive in-cab sound.
