    I am wanting to put long tube pace setter headers on and an x pipe. But i would like it quieter so this is what leads to my next question. Has any put two flow master that each are dueled out the back which makes it a quad exhaust?

    By putting two mufflers on an exhaust system that has no cats would it help make it quieter?

    Or if that does not make it quieter what would be yalls suggestion on making it quieter?

    Dual stock mufflers would be whisper quiet and would breath great due to sharing the air flow.

    Wouldn't that be similar to he late 60's when they put a resonator just before the end of the pipe? SO gut the 2 in line mufflers and then you get less sound????

    If im not mistaken wouldn't putting 2 mufflers in line hurt air flow? But i could be wrong.
