Well, my Road Runner which I recently re-acquired certainly has a drone loud enough to annoy my wife and it does bother me somewhat too.
Im pretty sure they are stainless flomasters right now, and I will confirm this tomorrow,
So I am looking for recommends on descent sounding mufflers with no drone.
It's currently a fresh 383, somewhat Lopey comp cam, with 2 1/2 inch exhaust to the bumper.
Please help so my wife will actually want to cruise with me

Get a nice factory type muffler from Accrete Exhaust. I remember when my RR had the factory mufflers, and it was quite until you stepped on it, and it didn't drone.

Keep what you have and add a pair of "cherry bomb" brand glasspacks alongside the rear leaf springs. O'reillys has em for cheap. the louvers are punched outward & the end nipples do not neck down where they are welded to the main case both of which are beneficial for good flow & they do work.

I run Summits stainless on my 440.They have a nice mellow sound pretty much straight thru but when crusing they are nice.Put them on at least 12 years ago and they still look pretty and shiny.That and no seams and were like 60 bucks each.Rocky

Put any cheap bullet glass packs in the tail pipes to deal with the drone.

Oooops. Mufflers are Terminators. Who makes a terminator? To the other two who recommended adding a cherry bomb (essentially a resonator) how will this prevent drone in the existing muffler?

Terminator mufflers are made by Flowtech Inc. Do a Google search to see where the closest dealer is to your location.

The exhaust pulses going through the pipes create an unpleasant resonance. That resonance is the drone you hear. Adding resonators modifies the resonation and reduces the effect.

The exhaust pulses going through the pipes create an unpleasant resonance. That resonance is the drone you hear. Adding resonators modifies the resonation and reduces the effect. Is this achieved by increasing back pressure? I never knew that it was the resonance in the pipe that caused the drone, always thought it was the muffler?. I'm just the kind of guy who really likes to know what's going on before I spend cash.. (Read cheap! Lol) As and UPDATE TO ALL: they are currently a Dynomax muffler 20" long body and about 24 1/2 to 25" long from tip to tip of the inlet & outlet. The inlet and outlet size mic'd to be close to 2.5". Do they use ID or OD for determining what size inlet and outlet are? From their web the best i can say is they are the 17513 model. It is also a welded muffler. Does mean it's stainless? I'm not adverse to adding a resonator, but I really don't want to butcher the exhaust further if this does not cure it.. All this input is great! Please continue!
