Am thinking of putting dual exhausts on my 69 Camaro conv. It has a 350 ci with 2 barrel and automatic. I want a mellow tone. A local muffler shop showed me Xlerator turbo mufflers, made in USA no less. Looked to be about 15 inches long each with 2" inlet and outlet. Quoted me $400 installed. I don't want a hot rod sound. Anyone used or using these? Thoughts?
