I really cannot say, I have only been up close and personal with the M version. I do know that the M XMBR has "HP" painted on it.

Considering the narrower axles/trailing arms, the pickup points may be relocated. No proof though

Seems that somebody thought the M piece was a heavier gauge, but I have no way to substantiate that, it may be pure speculation...
