Nah... most people I know leave their sleds pretty much stock. Exhaust is a popular thing to change, and often people add some tunnel storage, but that's the extent of a typical owner around here.
Very similar to trucks. Most Tacoma's on the road are stock. Maybe a stereo, a canopy, or a different set of rims here or there. I used to practically live on a Tacoma enthusiast forum and that place would give you the impression that $50k in mods was "normal".
I plan on leaving my Yamaha mostly stock with some added storage. If my Tacoma is any indication there will be sawzalls, forced induction, and a crying bank account in my future.
