I have Flowmaster series 40 mufflers on my '72 440 Cuda and hate the resonance at low speeds. I was thinking about switching to Dynomax Ultra Flo or Magnaflow mufflers. Also read somewhere that the Pypes mufflers were a lot like the Magnaflows but less $$$. What mufflers are you guys running and how do you like them.

Not a big fan of my Ultra Flows. 3" exhaust with x pipe on a 73 charger. BIG time drone between 2100-2400... Just my setup I suppose. Will be going super turbos next time. But they havent rotted or broken baffles like all the chambered mufflers ive tried have.

I normally run Ultraflos but I don't think there is much difference between them as they have the same basic design. Not much that has lower back pressure than the Ultraflos. I think the Magnas are similar.

I have a 3" exhaust with x-pipe and tailpipes exiting through rear valance if it makes a difference.

I have a 3" X pipe system, turn downs after the axles, and 3" Magnaflows. No drone, not overly loud at idle and cruise, but barks when the pedal is down. I made a little comparison video a few years back when I had switched from Flowtech afterburners to Magnaflows. The afterburners did have resonance, but that was gone once I installed the Magnaflows. The afterburners did have a cool classic sound though. http://www.youtube.com/watch?v=-vc2zqjSTjs
