Hello! Does anyone here have the part number for the undertail exhaust can for a 2005 GPR50? Or do you know if the end can is the same as a GPR125? I just bought a GPR125 that had an Arrow exhuast fitted, and I got the original front pipe with the sale, but he didn´t have the stock can. I found a stock can for a 50 on Ebay, and they look the same, but not sure. I know the front pipe is different, but the end can looks very similar. No Derbi dealers here in the US to call and ask. If anyone knows the answer to this I´d greatly appreciate it! Thanks, Dave
