Don't know what sounds best to your ears, but I like Brockman Mellowtone Steelpack mufflers. Either 12" or 17" size.
They let me enjoy the full range of sounds that my dear 235 and 261 make, but without the obnoxious noise and massive dB assault of straight pipes.
Stay away from the new repro Smithys, no matter what you hear.
They are nothing like the originals.
The new ones inner tube diameter is too small and has too many rows of louvers.
They are too restrictive and the dense glass packing gives it a plastic like clapping sound.
Not at all like the original steelpacked smithys growl.
Flowmasters sound too artificial and nothing like a traditional straight 6 to my ears.
You asked for my subjective input - there you have it.
