David- The straight pipes, fitted by the factory in Summer 03 at Assembly Number 51797 for 575Ms, have been proven in direct comparisons on dynos to produce more hp and torque than X-pipes. Not that much difference, however, and some prefer the sound of the X-pipes. Not me, with straight pipes and HGTC rear exhaust. Early Tubis (no 575 on cans) and straight pipes are too loud, and so are many aftermarket exhausts without valves.
Everybody's tastes in exhausts are different. My favorite are valved Kreissiegs for aftermarket, which give a very high pitched sound in Maranellos. Capristos have a deeper sound, my Novitecs were very loud (now on a 550 and he loves them, too loud for me). Like John said, just replacing the center muffler/resonator/cork with straight pipes and stock rear mufflers sounds really good on 550s or early 575s.
Larini, X-OST, etc also sound good and are not as expensive. So many choices, hard to know what any one person will love.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
