Suggestions for muscle car sound muffler without drone

I have the Thrush version of the Flowmasters, 2.5" mandrel from header collectors. Nothing attached at the end of the muffler, so exit in front of the axle until I get around to doing the tailpipes. Hopefully they will help, I forgot how boomy chambered muffs are.

Magnaflow is really the way to go, and might as well do all stainless if you do that, never have to redo it again.

I never liked the Dynomax or other turbo muffs. Too quiet, don't sound mean at all, flow like crap and rob power.

Glasspacks can sound nice but kill your flow with the louvers. Use perforated core like Magnaflow instead.
