Here there guys, i'm new to this site but i've heard there are a bunch of very knowledgable people out there on this site. I just wanted to ask you guys what u thought of this setup:

I have an Apexi exhaust system, AEM cold air intake, BMM fuel regulator, and i was looking for a really good header that will give me the best result.


any recommendations?

 

Putting a header on a car with a stock cat converter and stock exhaust system will do absolutely nothing except look good.

 

The stock header is already a great part, however it is designed for the engine as N/A. The only time a different header will make noticable power is if you have FI.

I have had both Mugen (N/A) and Comptech (F/I) and are very similar expcept for the actual bends. Both are dyno engineered as is the Spoon header and a few others.
However beware, unless you have a turbo or supercharger, you may actually loose power in the mid-to high RPM with the addition of the header in exchange for a little (and I mean LITTLE) low end torque.

(just my experience)

check out the toda header, it is quite the contrary to what you just said. A search will reveal a thread discussing this topic already. You'll need some sort of fuel management other than stock to many power on this car if you plan to mod it N/A.

 

there are many ex man out there for the s2000....
dc sport, toda, mugen,amuse,rsr ,feels,etc....
the hp gains are little to none...
the weight loss is a big improvement...
i have an amuse ex man in my car and i love it......

 

I saw over 10hp with the toda header, and the car is going in for more tuning as only a very mild fuel tuning was done.
