No, I mean, like, why are the "turbo" style quieter?

they snake through the muffler casing passing the glass insulation the whole time as opposed to chambered styles where its got no insulation or ones like the xr1s where they do have a insulation but its straight through design.

I am ready to pull the trigger on Stainless works mufflers but the Flowmaster 40's make me pause.

I took a long look at those Aerochambers... the internals look interesting.. and I've heard them on an LT1 Malibu and they sounded amazing...

Would love to hear more feedback from others running them...

OKay. hurry up with the video!! You've got plenty of time on your hands.. LOL

Magnaflow, 2.5 with an Xpipe, Had Flowmasters on my 70 Monte Carlo and hated the drone sound.
