Which header is worth to get (best bang for bucks) give more HP and TQ
price approximately as follow:

SMSP 1250
Prospeed 550
Imagine Engineering 550
Mugen 900.

 

Well there werent any real tests, but IMO the one header with the most quality put into it is SMSP(also made alot of power on coreys car, with his stock motor he made 205whp). All Slip Jointed, along with the best TIG welding. I have one for sale also, check my Sig.

no doubt that smsp is a great header, but money wise, i don't think it worth it. those prospeed and imagine engineering cost only half compared to smsp but made almost same hp.

 

Well i remember the imagine engineering header showed not too good gains. As for prospeed, people have had alot of problems just getting the god damn thing to fit. Some have had to notch the **** outta their cross member. And also when you add in figures like a merged collector and stainless steel piping it comes to cost almost about a G.

 

I thought imagine only made an H22 civic header.

He has a dc2 hybrid. No notching for him.

I see. Yea well i guess the prospeed header would work then. I dont know how the clearence is though of a h22 in a DC2 though using the prospeed header.

 

firstly, the smsp, prospeed, and mugen are all in a category way above the imagine peice.

the smsp being the most expensive, shows great hp gains, but the prospeed is very close to smsp's #s, if not better....

EDIT: the prospeed you would need to get to be comparable would be the merge collector, so thats $700, and then if you want it stainless, thats $900 now....

and next the mugen, comparable to a jun header....there are dyno sheets on here proving that the prospeed outdoes the jun header by 8whp or more, i forget, but junbb1 did the test, search for it.....the jun and mugen are almost identical....

for the 550 that you would spend on the imagine you could buy a greddy and do the 2.5 collector mod and still have more than $100 left over, and i believe the modded greddy will outdo the imagine.....

if anyone has real #s proving or disproving what i assume, let me know....

 

i see SMSP :drools: man you must be a baller to own all those parts you have f/s mr. fuego.. if i could afford that header i would buy it. i can't even afford the SS prospeed header for greddy header w/ collector mod. btw from what i've seen the prospeed makes really good top end numbers but i don't know if it makes or loses midrange being a 4-1 header. i think some dude did a header test a while back and never posted the results cuz we're people and people sometimes have attitudes if i'm wrong someone chime in.

 

If this thread is looking a the mid to top-end headers compared, why omit the Hytech? They also can custom tailor.

werd

 

What about Fujitsubo?

 

I don't consider the Mugen to be special at all....

agreed.

 

the whole point of this thread was to show numbers...noone should any, you guys have anything? especially for a prospeed?

 

I am busy at Noone.

 

There was a dyno On SGTs site where it was showing coreys old motor with just I/H/E making 205whp but his site has been down forever.

 

not sure if this is relevant ... but anyone have any words on an erick's racing header? not sure if it's a custom order or they have them readily available to buy.

once i get an emanage, get it tuned, i'll have dyno's up of a h22a4 w/ CAI/Prospeed stamped/HKS superdrager up.

but that won't be happening for a little while. maybe sometime in january?

 

Ive heard that the 'Rage' header (kteller.com) is good comp against the prospeed header, anyone else got any news on this on?

as i want the best for my lude its a toss up between the smsp.prospeed/Rage header.

usual bolt-on apply

i also have a Vafc not fitted yet is it worth fittng when i choose the header?

 

Back in the day (around 2000) a few of us threw in a few bucks each and had the "Great Header Test" done for an R with only i/e on it. We paid some guys to rent a dyno for a day and do the tests with each header.

The candidates were SMSP, Hytech, 2.5" Mugen, Toda, jdm DC 4-1, Comptech 4-2-1, and one or two others I can't remember.

Dave from SMSP also threw in a complete cat-back of his to test with and a Carsound high-flow.

If you do some searching, the results are around I think. Bottom line is that the custom 2.5" 4-1 tuned headers performed the best. The best bang for the buck was actually the DC jbm model. It was not far off the Hytech/SMSP/Toda plots (they were the best). But what the test doesn't tell you is the effects AFTER getting more mods done, specifically internal and cams. With those, the three listed would blow away the rest.

Now I know the H22 is a completely different engine, but the principles are the same. I'd put my money on the SMSP/Hytech models every day of the week. If you are going to do it, do it right the first time.

That's why I'm trying to scrape together the cash to buy Bfuego's SMSP ....

 

Thats right sweat heart.

 

I have just installed the kteller rage header last night on my car along with a 2.5" - 2.25" high flow cat from Kteller (great company).
Its odd, I feel losses of power in certain rpms. But once vtec kicks in I'm feeling the gains. However, I'm certain dynotuning would bring benefits everywhere. Dyno tuning is in order!! I'll keep you guys posted

But, my exhaust note is killing me. Sitting in lower rpms their is a real nice growl now. But, My apexi N1 is giving me a terrible bumble bee/dirtbike sound just prior to vtec, and all through it. I've never heard this before and I want to fix it. Any suggestions. Kteller told me to replace my resonator with one from magnaflow to start with. And if that doesn't do it, replace the muffler. Sounds like a good start, but I want more opinions on how to get a nice deep growl.

 

the Prospeed header is a modified Rage header. It is built by the guys at Rage. The design of the piping is SLIGHTLY different, but rest assured they did make it.

Dont install a high quality header and expect "bolt on power" It needs to be tuned to show results.

Also, if your car sounds like a go kart / uber rice rocket with a giant fart cannon on it, swap to the big *** magnaflow resonator, will solve your problem.
