they'll be loud enough to let ppl know you're coming. I can hear that truck in the above video for about 1/2 mile or 1/4 mile beofre it gets here depending on how hard it gets ran. You go about half way from here, and there's a railroad crossing, then about the same distance and you're on the main 2 lane. I could usually hear dad leave in it, hit 3rd and idle down to the tracks, then if he gets on it afterwards I can usually hear it until about 3rd or so. It aint too awefully loud next to it or anything, not like open headers, but loud enough you know it's running and know it's coming, IMO it's perfect. it's deep like flowmasters, but loud like gaslpacks or straight pipes, but doesn't crack and pop like glasspacks or straight pipes. Haven't got around to getting a driving vi though. it's sitting in the yard right now waiting for the wheels to go back on. Just got done putting all new front end under it, ball joints, tie rods, control arm on the top DS. Almost everything on it has been changed or worked on.
