I just bought an NSR 150 RR (1995). I've been on Tyga page but I only see parts for the SP. I want to buy the expansion chamber and end pipe. My question is will it fit my RR or I'll have to cut the body work? Thanks in advance.

By the way, is there more info on the 150? I've been through page 10 on Google search about the 150 and I want more info (damn, I wish I know Thai or Indonesian).
