Muffler recommendations 1965 barracuda 273 original exhaust manifolds.

I wouldn't ordinarily recommend glass pack mufflers, but I put a set of Cherry Bombs on my 56 Plymouth with a stock 277 poly with four barrel carb and dual 2" exhaust. I was afraid it might be obnoxiously loud, but it's not. Just a deeper, healthier tone, but a lot quieter than the Sonic Turbos on my more powerful stuff. It does have that glass pack crackle when you rev it up and then let off the gas. Any old fart reading this will know what I'm talking about. I think it sounds cool.
