Big loud pieces of crap. Loud pipes my ass! Just another machine for foolish testosterone addled fools who need you to notice them on their loud expensive machines. Kind of like a ricer for the middle aged set. I love the springtime so I can open up my windows and hear these aZZholes going up and down the street. Phug them and their $30,000 Hey look at me machines. Just goddamn silly to spend that kind of money for a piece of junk.
