I installed a set on mine in about 10 minutes. Solved the low RPM surging for me. Best $150 you can spend on the MultiGet these, they do work. -> PERFORMANCE BOULEVARD - O2 Manipulator
You have to email them for the MTS part (? update the site, jeez) I'll look through my email and see if I can find the part number, you need two $150.00 for the pair. Money well spent.

Item# O2M- MULTI/DIAVEL $150.00 USD 1 $150.00 USD
