Don’t get the platinum. The coating easily chips if it takes a hit, almost like it was spray painted on. I have been running the Works for a year and a half now...love it.
There are no pipe guards available for PC pipes on Betas. Just get the pipe repair kit from eBay

I use Ospho for rust in the spots I can’t scrub, but using a green Brillo pad on it every now and again keeps it in good shape.
I have been told that the FMF Gnarly is similar to the PC pipe but I haven’t personally used it.
AXP Extreme skid plate works great. You can trim the alternator side so the alternator cover can be removed without removing the skid plate.
