Do you want noise, or mufflers that actually flow?

Here is the inside of a Super Turbo. I think I found this picture on here and saved it. I don't like the way the exhaust flows right into the exit pipe. For low hp applications it probably doesn't restrict the flow much but I wouldn't want to use them on anything that is making good power. I'm not really a fan of the sound of these either. Exhaust sound is a very subjective thing. go read the article linked above.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Unless I'm missing something, both Dynomax mufflers listed in the article are offset inlet and outlet. Those are designed differently inside. The center outlet design is the one that looks restrictive. Not really - they simply cross-flow internally. The sCFM #'s for offset/center, & offset/offset are about the same - around 410 sCFM's for both 2.25" & 2.5" Super Turbo versions. Still, Super Turbos do not do much "tuning" of the sound, but they do more than Ultra Flows. Ultra Flows are like oval glasspacks & other straight-through mufflers. Flowmasters TUNE the sound, but they do not flow impressive sCFM's because the plates internally cause quite significant restrictions.

I ran FM 10 series on my fury for a number of years, what's all this complaining about their big mufflers 😎 I do have summit turbos and tailpipes now, plus the turbos themselves, much different now.

Dynomax Super Turbos are restrictive as he11 and definitely hurt power! I like Flowmasters personally, but know a lot don't. Never seen the performance drop from Flowmasters a lot claim though. Had a set of 3" 40 series Flowmasters on my cuda w/ a 440 that ran 11.40s in the 1/4 and it ran the same w/ the mufflers or without them.
The Dynomax Ultra Flow, Hooker Max Flow, or Hooker Aerochamber are very good flowing and sounding mufflers too.

I had Flowmasters on my 70 B-body, and the drone at highway cruising RPMs was AWFUL.
Switched from manifolds to headers, then switched from an H-pipe to and X-pipe while keeping mufflers the same. Got a little better, but still droned badly.
Your mileage may vary, but I would not use them again.

I think I've ran em all lol I tossed Dynomax Super Turbos on my daiy driver Cordoba, 2 1/2" mandrel bends out the rear coming off Hooker SuperComps. Love the sound honestly. No drone, nice sound and fairly quiet at cruising speeds. Best Flowmaster sound I have heard was my motorhome, I loved it. Healthy hydraulic roller 360, headers, Y-pipe into SINGLE 3" exhaust and two 3" Flowmaster 50 series in TANDEM. I loved it. Quiet and gorgeous tone, no drone.

It took a couple tries but I felt I got it perfect on one car, I loved the sound of the 2.5" 20" super turbos on my 5.7 magnum r/t daily driver (manifolds, jba catless mids). I also tried 2 chamber flowmasters and hooker aero chamber on it. flowmasters were too loud for long drives for my taste, hooker was slightly quieter but still just a little too much sound. The 20" dynomax required some light fab work to fit, but I liked them the best. The problem with alot of late models is most exhaust for them is spec'd with cats which kill alot of volume. Go catless and suddenly everything is louder and more droney.
I loved the sound of hooker aero chamber 3" on my GTX when I had H pipe, 1 and 7/8 comp headers, and almost the same engine combination as now. However I was chasing power so I went slightly bigger and with ultra flo. I also like those quite a bit. the power thing worked out ok in conjunction with other changes.
For short blasts in a hot rod I'm ok with the classic flowmaster thing, but they better be pretty short drives. To jump in and drive for a couple hours, I'd have to go with old-man 20" super turbos. I believe these are what used to be marketed as hemi super turbos....
