OK, first of all the "ZZP" ceramic coated crossover is just a stock crossover coated, so there is no benefit other than lower temps. That's why they ask for a core.

As for doing them all yourself, I don't know, but I imagine there is a shop that could coat them for you locally prolly.

You are right about the rear not being as restrictive as the front. You could easliy get away with only getting the front and crossover if you wanted to. I actually doubt you'd even see a difference adding the rear to your setup (if your sig block is right).

See, I have the rear and a 2.5 dp w/highflow cat, but now need the front and a catback before I'll even consider adding them! I also found out that I prolly won't even add it because it's more a$$pain than it's worth. I would much prefer headers but you know how much they are!!! Plus, I'm not trying to make a race car, just a slightly faster one!!!

Hope this helps a bit!
