WTF Is wrong with people?

My brother does that same kind of ****...I sold him my old 95 s-10 (good running truck) for next to nothing and he ripped the dash apart and painted parts neon colors, took the rear roll pan off and put a coffee can sized muffler on it, hacked the air intake apart and used sewer drain pipe and a conical filter to create his own "custom" cold air intake and then cut holes in the hood to put a reverse tiny induction cowl...he thinks it's cool and has like 80 extra horses now and thinks he's improved the mpg from 25 to 40.

Can't stand it, but it's his and I don't have to drive it, but the sad part is I could've gotten three times as much for it if I'd have sold it to someone else.
