Maybe I'm just a no0b but wouldn't the "loud and obnoxious" part really depend on the entire exhaust system and not "just" having aftermarket exhaust headers? I mean, I know it will have an effect on the sound and would probably even help to make stock CBE sound nicer but something tells me the effect will be very much related to what CBE you are running and whether you have a test pipes, high flow cats, or OEM cats.
