I've heard folks say, "It sounds like a V8." But, to me nothing sounds better, or more unique than a sweet set of duals on a six. I can't understand how anyone could mistake the difference.
I installed a set of flowmasters on my brother-in-law's 258 Jeep. They sounded "tinny" to me and took up more room than a set of round fiberglass mufflers would. He didn't like the sound of 'em either, but paid too much for them to take 'em off.
One of the sweetest sounding sixes I ever heard was a '53 plymouth six with dual-outlet cast iron headers and Belond mufflers. 2" pipes ran out the rear. Belond mufflers were popular in Florida, back in the 50s. They were just a little quieter than Smitty's; I guess they're long gone, now.
