Muffler recommendation for LS swap

[FLYNAVY53]

Im posting this in the LS section as Im specifically looking for recommendations based on muffler sound with an LS, not exhaust system routing for a specific platform.

Ive got a '72 C20 Suburban with a 6.0L LS swap with a decent size cam and Holley fuel injection. Right now, Im running Flowmaster's 2.5 inch dual exhaust system with H pipe and 40 series mufflers. The system overall is fine for my daily driver application....my big complaint is the 40 series mufflers. They sound great at idle and really low RPM. Above 2100, they drone horribly up to 3000 RPM where they start to sound like a fat guy farting through a Tuba.

I'm looking for a recommendation for mufflers that have a deep, mellow rumble at idle, quiet and no drone in the mid range cruising RPM, and sound good at WOT without sounding ridiculous.



Any input would be greatly appreciated!
