The performance gains from RG3s over stock are marginal anyway. You get RG3s for better sound and still having that factory look. If you want power look elsewhere. There is a thread in here somewhere comparing the RG3's to other aftermarket options. BUT I have not seen one on differences between RG3 sets. I would suggest it is negligible, akin to splitting hairs.
