Flowmaster Delta Flow?

[SilverStreak88]

Anyone running or have run a Flowmaster Delta Flow muffler? I ordered a 50 series DF si/so, I was told by FM some time ago that the 50 series was built for the Hemi, but I just checked and supposedly it's the 50 HD not the DF. I wanted see if anyone can report on power loss/gain with this model, I'm back to stock now cause I got tired of the drone and the 50 DF is supposed to be little to no drone, but good sound outside. Thanks in advance

Interested in this... I'd like to swap my muffler soon.

Their Delta Flow line does what they advertise it to do. I had their 40 series delta on a Mustang years ago (302/5.0). There was zero drone inside the cabin and the exhaust noise/volume was very reasonable. I doubt there was much... if any power gain, but it sounded good (perfect for a daily driver).

I've used the 10 series ones on several vehicles. They're pretty much my go-to muffler of choice.

I got the 50DF welded up this morning at work before I had to do some real work. Tried doing some sound vids this evening, but they aren't working even with a HD camera. Basically all I can say is that I can just barely hear it over the Cooper's, she has some growl when you take off and sounds nice, but quiets down pretty quick. Low end torque seems to be OK, but when I jump on it from cruising speed I don't feel it like I did at stock. I'm sure it'll grow in me, I'm just used to having loud exhausts and now that I'm older I can't stand the drone and obnoxiousness.

Yup. It's definitely subtle. You can hear it when you want to hear it (when you put your right foot down), but otherwise...those around you might think it's a stock muffler.

I'd look into magnaflow, super quiet at idle or low rpm but throaty when you mash it. Awesome pic of Piper, I believe he was talking about kicking ass and chewing bubble gum lol.
