      moroso spiral flow mufflers

      Has anyone used the moroso spiral flow mufflers on a 69 camaro, mounted between the gas tank and rearend, like the original chambered exhaust ? And if so how much interior resonance is there? ( at 65 mph, I'm turning 3200 rpm with a 396, it's a little loud with the old flowmasters!)

      I haven't tried them yet, but here is a cheaper option for basically the same thing:

      These fit in 3 or 3.5" pipes. I have them in my tailpipes of my 67 El camino as secondary mufflers. Just another option.
