They seem really interesting!

Looks to be more restrictive than a stock mid muffler.

Gimmick?

Maybe it brings out the flavors in your exhaust

lol..sooo no one knows ?

Looks like its trying to add some venturi effect to speed up the exhaust but I would be concerned about the inside diameter looks to be reduced in size in order to make those nifty little cyclone ridges.

Exactly my thoughts man. But I have to see it closer in person to know how restrictive thu, was hoping on some insight regard the technology or experience, sound, drone etc

Back in the day aeroturbine 3030 was the thing for 5.7 hemis.

It's a good bet this is just more restrictive. You're forcing the exhaust gas to twist around.

Man that reminds me of the rumblebee.org days. Everyone ran those nascar style mufflers

yeah, that could be true but it is also suppose to vacuum gas out quicker..not sure what to make of it

Pleasant exhaust notes come from valve events/cam timing not mufflers.

Mufflers are just that: things that muffle sound - more or less. Turbo style, glasspack, chambered, Flowmaster esque, turbine, etc allow different amounts and frequencies through. The quality of sound is 90% in the engine.

Headers, cats, pipe diameter, muffler quantity and design, and even exhaust tips are all secondary to displacement, compression ratio, chamber design, cam design.

Making a car louder does nothing to improve engine quality. More louder isn't better. These cars have emissions cams and it shows - especially at idle.

I think it is more to do with sound production than any performance benefit. These midpipes should be very poppy.

I second this ...... I just went through all these exact scenarios this summer .

With in a reason yes. The tone of the engine will come through and dominate no matter what yes, but I dont know about 90%. I Heard the 6.2, 6.4 with chambered mufflers..it changed it quite a bit, you coundnt tell it was an SRT..sounded so so damn good though, however chamber restriction steered me away. I'm curious about this one cause its an interesting design .

poppy as in pops and crackles you mean? why so if you think that?

 

[Himmelkat]

Not as in "¡ay papi!"
Not as in opium poppy.

Aside from tuning an exhaust to run rich and push unspent fuel into the hot exhaust (thus exploding and creating exhaust overrrun), the other way you can create similar sounds is by creating pressure imbalances. On custom exhausts, you can crimp the pipe in 5-6 equally spaced crimps to get more rumble and pop out of them. This seems like it would do something similar with how the twists will likely create vortices of low and higher pressure air.
