go with the Pacesetter ceramic coated header. Pacesetter's header is super easy to install and is a nice piece.

As far as the cat get the Magnaflow 91035. That is the one I have on my 04 and it works fine.

Header----just search this forum for a decent place to buy---I got mine at Turbo Tech Racing.

Cat--- JustMagnaflow.com

hows the rk header hold up compared to the rest of them

From what I've heard, the RKSport one kinda sucks, the Weapon-R 4-2-1 Header is better, although some say its the same as the RKSport which it kinda does look like it. If you want high end power get a 4-1 Header, if you want low end torque then get a 4-2-1 Header. Atleast I think thats the "equation."

No one can say what is the best because everyone has different preferences and certain headers supply more power more on the low end and some on the high end. I personally like Weapon-R's header because I have it and have had no problems with it but that's just me. The best thing for you to do is go around, see what's in your price range, see what kind of results or problems people have had with them and see what style header you want.

Good luck on your search.

It has all the necessary holes but it is not ceramic coated. If you want pictures, check my registry.

I just put the pacesetter armor coated on my 05 and a magnaflow cat. Get the 94035 cat not the 91035, the 94 is bigger.

He's right---I posted the wrong number. the 94035 is what I got.
