I am getting close to pulling the trigger on a header. I know a lot of people have the OBX. I also saw a GB on the Thunder headers. I don't want anything really loud, but most importantly, what header is the better product? Which produces more HP? Are there any fitment issues? Thanks for the input-
Which header?

I can only comment on the OBX, and can say it's definatly worth the money to me. The power improvement was great, not a ton more sound, less than a CAI, and the quality seems very good (I've only had it installed for roughly 5k miles so can't comment on long term).
The OBX seems like it would make more power than the thunder because it's a long tube design, vs. the thunder with a shorty design.

Any race header is gonna give you a pretty nice gain in power and torque...The best are gonna be a 4-2-1 which only comes from Mazdaspeed Japan or I think AWR used to make them...As far as the 4-1...All the same...your splitting hairs if you are trying to get more gain from one or the other...I've heard the Thunder header is well built and fitament is great...As for the OBX and Ractive...I've heard good and bad about the fit...I've got an OBX and had to wrestle it a bit, but the fit is good and the gains are "noticable"...not amazing...

Warning: threadjack in 3....2....1.....What coilpack is that you got there?rednecks_r_us said:
those are stock coil packs, with the Nology set-up.
and...what are you talking about?!?! the OBX and Thunder headers are basically the same thing. only difference is the thunder header has a joint right after the "collector."

I had on OBX on my GSR and didn't have any problems with it. Noitced nice gains from an inexpersive mod but that car to ours is Apples to Oranges.

I recognize the wires but I just bought "stock" coilpack to mount in that position but all 4 holes for the plug wires face up in a row, they don't face 2 different directions like in the pic above & the bracket looks different, hence the question. Here's what my "stock" ones look like..........http://www.msprotege.com/members/i12drivemyMP5/coils_2.jpgnjaremka said:

The header with stock exhaust is not very loud at all....Probably makes less noise than my CAI....Add a high flow cat...Then a little louder...Add any cat-back and it'll be loud under acceleration, but with a nice Racing beat muffler it quites down real nice when cruizing...If you keep the stock exhaust...It will not make you want to punch a baby...

i have thunder and it is great, no fitment problems and no check engine light. not much more sound to my exhaust that i can really tell cuz i always have my music on.

I'm just running the MP3 Racing beat axle-back...and it was the last part of my exhaust system I put in...and it by far made the biggest difference in the sound of the car..
