I have a hopped up B motor, high compression head, Cam, dual 48 carbs, etc... the whole she-bang... header into a long Smithy muffler...
its not very loud and annoying, but you can tell its not stock... but still has a rumpity sound to it....
this isnt a great example... but heres a video where you can hear it driving...
