I have held the XeMODeX unit in my hot old hands and have had it installed on my son's 2000 v70XC. It went on perfectly in about an hour and started instantly. 0-60 times were the same as before and the idle was smoother.
Since they have to do internal work beyond the end caps modification is not a DIY job though the installation could be.
