Sound, as was said, is really subjective. I’ve got a pair of hushmasters on the bird, and they were so “ rappy” at full throttle I had to put a set of resonators behind them. I’ve got an OT car with Flowmasters that are pretty good. My buddie has Smithy’s on an OT 56, full size car, and they really sound the best of all to me.

I have a set of the old red glasspacks that I put on in 1987. They've been through several engine combinations and have only had the other pipes replaced once in all these years. Talk about sound! Nice thumping idle and slightly more than a mellow sound. The also rap perfectly when you get on it. They have certainly worn in well.

Y's guys rule!
Looking for McCullouch VS57 brackets and parts. Also looking for 28 Chrysler series 72 parts. And early Hemi parts.

 I have the Smithys glass packs on my ’55 with a 272 and they have a nice mellow sound.  These mufflers are only a bit over four years old now.  As they get older and the internal packing deteriorates, I’m sure that they will get noisier but right now the exhaust sound is just mellow without any harsh popping or being raspy.

I like Magaflows. Perfect muscle care sound without the harshness or din.  Of course I'm half deaf anyway. 

Too loud is subjective.  I had some glass packs Flowtech Purple Hornies, that would cause my ears to ring after a short time on the highway.  I changed to Hooker Aero Chamber.  Still noisy, but doesn't make my ears ring and conversation is possible without just about yelling. Idle tone was about the same.  That's on a 300ish hp engine.

I used the same glasspacks on a lower powered motor, with smaller exhaust pipe diameter and they were fine on that.

I'm not actually tied to any brand of muffler.

I have a 292 and installed Brockman mellow tones, they were too loud, I put the old Smitties back on, but the have pinholes and also are a little too loud.  However they are quieter than the Brockmans, but they still tend to rap.  I want mufflers with a throaty exhaust note, I just don't want the rapping.  I am considering an Amazon Total Flow 31245.  It is a turbo muffler.  Has anyone used a product like this.
