what headers can i get the most gains out of most popular which everyone has is dc....but i dontknow the gains if any.... and if i do go with dc i should go with ceramic right....and how are the greddy headers.........just tell me which headers are best lol
1. What model of Prelude?
2. What engine?
3. What are your goals for the engine?
4. What is your budget?
5. There's no such thing as the "best" header.

y are these headers so special and what kind of gains can i expect out of them also what do u mean a custom exhaust i have a apexi n-1 with custom piping which i can take off the pipping and use the muffler right and i dont have to use a cat i can just testpipe it right.....which one is better hitech or smsp

Both of these are much different than most on the market because the use larger diameter tubing throughout the header, longer primaries, longer secondaries, a larger collector, and slip joints instead of flanges. They are also custom made, i.e. they aren't mass produced. AFAIK, only 12 or so of the SMSP headers exist, although he is doing another run. I don't know of any production HiTech headers in existence, I've only seen prototypes.
You have to use a custom exhaust with the SMSP, as the collector is made to use a donut flex joint like the Civic, S2k, et. al. It does NOT use a stainless braid flex like the stock exhaust. The collector is also a larger diameter, so the stock cat wouldn't work anyway.
The prototype of the HiTech header I saw had a flange to bolt it to the stock cat, but the collector was a larger diameter, so why bother?
If the Apexi N1 you have has a 2.5" inlet, then you can probably use it. If the inlet is smaller, I'd **** can it, but that's me.
As for which one is better, it really depends on your set up (hence the reason why there is NO best header on the market). Dave (SMSP) made 3 versions of his header, one that was a copy of his 5th prototype which was for a mildly modified stock engine, one that was for a more aggressive NA engine (this is the one I bought), and one that was for an FI engine. His 5th prototype made around 205 WHP on a 4Gen H22 with CAI, open exhaust, no PS, solid crank pulley, lightened flywheel, and a AFPR. I have yet to see any dynos of the HiTech piece.
DR made 197 whp on his setup with dc cc header and other mods.
check out his dyno on lepto header thread on NA forum
..
i made 175 on my setup 200 dollar dc header.
i cant wait to see the results of the smsp header dyno that TOdd is going to do to see if it really is worth the money

yes tuned ecu but if dc header was that crappy i dont think he would have such good gains.
im sure it helped.. now when they do the smsp header swap and if he gets 210 or 215 over the dc then i would say the dc really is that bad.
we'll see in a few days i think they were suppose to dyno it yesterday

back to original question, look at it this way also.... is it worth spending over twice the money (ie. mugen header) of the dc header to gain a minor hp increase?? also i could be wrong but i havent seen any clear cut data saying how much the mugen gained over the dc....
unless of course there is major gain when the smsp header is dynoed
