When I went from my stock 5.0 to a full Trick Flow Top End, my sound definitely changed. Got louder and the cam gave it a meaner sound. That was from bone stock to full Trick Flow top though.
Some guys dont know the difference between being loud and sounding good. I work with a guy with a Honda Shadow. I forget what CC. He always says, "wow, it's hard to believe that my BIKE is louder than your V8!" and I respond with "If I had 2 feet of straight pipe, my car would be a whole lot louder than your bike, but I know there's a difference in being loud and sounding good."
