Loudmouth with stock everythign from the cat forward doesnt sound bad. its not raspy ( ON AN LS1) and it sounds mean as hell when u want it to.....when ur off the throttle tho its NOT LOUD....i dont care what anyone says it drones a little at cruise but its quiet if u need it to be....headers and a LM on the other hand are generally thoguht to be a bad idea.....
