Buying a used bike is a bit of a different experence than buying new. Sometimes you like what they did, sometimes have to un-do what the previous owner did.
I bought a used Pearl 600RR in the fall of 07. It looked like the kid-squid that I bought it from, used it for a dirtbike. He had an alarm on it, probably because he didn't have any insurance. Anyways, he had this alarm strapped to the muffler. Needless to say the alarm didn't last long. I had to take that bike apart when I got home. But, it had only 3400 miles, and it's a tough little bike and it's not been hurt. It has a stainless exhaust also.
The pipes on that 6 looked even worse than the pipes on your 9. They're stainless steel and require a good scotch brite treatment at least 3 times a year. Nice lookin pipes really brighten up a bike.
