I've been wanting to get new exhaust on my truck for a while now, and was holding out for a 5" stainless system. I've heard lots of good things about MBRP, but they only have 5" in aluminized, and I'm not going to paint my exhaust every few years.

I saw on Magnaflow's website that they have 3 different 5" stainless exhaust systems, does anyone have one of those kits? I'm having a hard time telling from their website what the difference between kits is.
