125-200cc 125 Pipe fitment

I was wondering if we could get a thread to verify what pipes are actually the same. I'm thinking of getting a Scalvini for my 08 CR 144 and I'm worried that Scalvini lists the 08 and 09 as being the same and I don't think this is true. I think the 08 uses the older style pipe that should fit back to the early 2000's?

On one site I've seen HGS lists an 00-08 pipe and a 09-11 pipe. On another site HGS has an 00-04, and 05-08, and an 09+

Scanning info on this site it sounds like the 09 is a stand alone year and then 10 and 11 are the same?
