Yeah, as a replacement, the Megan header is just fine. I don't know if DC makes one for the F22A with a 2.5" collector, but that's the only way the DC would be significantly better than the Megan. Of course, you're in CA, right? DC is CARB exempt, whereas Megan is not. Pace Setter really isn't even worth considering.
The Bisimoto header would be over $1000 now, i believe. The cheaper price was for the group buy only, and that's over. It's definitely worth it if you're doing a serious build... but if you're not doing anything crazy with your motor, then it's a lot of money.
