Don't forget the stock exhaust with a slip on...
It's the same concept as the assholes that drop 30k on a Road Glide and then another 10-15k (minimum) on a 30-32in front wheel and air ride... Only to not be able to see over the windscreen.
There's actually a guy in my area that replaced his gauges with a tv screen and has a camera in the headlight housing because he can't see a fucking thing in front of him...
