MSDS is DEFINATELY a better choice. Fitment, warranty, gaskets, MILs, & hardware are just a few things that you don't get with WRs. WRs are a viable choice for those on a budget, but if you have a few extra $, the MSDS are gonna save you some headaches & heartbreak. Well worth it if a header ever cracks, or just to avoid having to deal with fitting the darn things.

MSDS are still the best.

Must be that jumbly-wumbly thing happening again.
