Just totally cut apart my stock muffler and rebuilt it after owning it a month. It's way better than stock. I have a 2014 w a BBK and big carb (how I got it). I drilled holes in the muffler and that helped... But loud and annoying. Now I cut it all apart, gutted the muffler, ported the head pipe, and ran straight 1in drilled pipe through a shortened muffler w steel wool and glass packing... Way deeper, quieter sound and way better flow. Loud isn't always fast.... If u got 6hrs and a welder, a grinder, a drill press, and an undying desire to hot rod anything u touch.... It's "easy" haha. But mine looks stock, down to the new inner fender mount and trimmed heat shield.
