Default Moroso Spiral Flows

How do these mufflers flow and sound behind headers with 3'' exhaust. I've converted to true duals and am doing an insert that is similar in design to these and are curious if anyone has used them behind an LS motor.

I have the Pro-Flow Twister mufflers which are almost identical to the Moroso's I beleive on my 3" duals and it sounds great!!

Lot's of people have those on their duals and love the sound.

Heres a vid of mine, not the best but you get an idea. I can get another one tomorrow thats better quality. I have pacesett LT's, no cats into an X with moroso spiral flows right after, and pipe out the back. Don't mind the start of it the damn camera kept trying to fall over.

I love the sound of mine. I had Dynomax bullets first and decided to swap to the Spiral Flows for a reduce in noise level. They aren't a whole lot quieter but have a much better tone.
