Hey, I wasnt sure where this should go so I'll just post it here. Anyways, I have a 400ex that is pretty much stock except for Razr tires. I am thinking about starting to race XC this summer and wanted to know what I should put on it before I start to race. I was thinking about putting on a WB e-series or FMF powercore IV silencer on it. So if anyone has any input on what I should add it would be greatly appreciated. Thanks in advance.
