Engine is 4.3 v6 .30 over, heads, and will have a holley 600 by next week.....I was curious would it be ok to run duals? I do want it to be pretty quiet, as loud v6's sound like.......Really just asking what type/brand of muffler or muffler you guys would suggest? Just any guidance on the whether to go true dual, an xpipe or what?
