Some guy is selling his custom made to fit his prelude sh for $450 shipped. I only plan on i/h/e with no tuning so i don't loose my atts. Is this a good header for that price our should I just save my money. Thanks guys.

 

well being that it is custom made for the h22 none of us would know or at least i dont i didnt even know rage made headers for a h22?

did he re flange a b18 header ir what?

 

You realize you'll gain nothing in an obd2 vehicle without tuning right?

 

I'm the op just different account. I'd probably tune with a vafc2 to save my atts. I'll get picks up tomorrow or whenever he sends them, he said it was made by rage racing at whitefield in CA. I've heard rage is a one step down from smsp is this true? Thanks again.

 

"Rage" headers are made in Taiwan or something knockoffs of Hytech B-series headers. I've never heard the name attached to an H-series header although I guess it's possible.

 

Sounds like a rip to me. I wouldnt bother with it. Just go for a megan header if you can. You can get one for less than half the price that guy is charging you. Dont know if they make them for SH though.

 

The guy said it was built by whitfield, who from my understanding has a good reputation. I pm'd the guys there and asked if they had ever built such a header. If I run I/H/E without a tune I'm not going to run lean or cause anything bad to happen to my engine right? Thanks

okay cool. I'm waiting for some pics of the header.

 

Just got picks and it looks like that "turbo manifold" design header made a while back. It's jet black coated but there appears to be rust on the bottom piece where it connects and there's a little dent. Not $400 material in my book. Thanks again guys

 

the rage header use to be sold by kteller. and it was pretty much a copy of the first RMF design. just like 98Vtec's header. they sold for like $650 new if i remember correctly. PM Kteller and see if they can tell you anything about it. they might remember it even though its no longer carried there.

 

The rage header is the same as the an-r header, and is <u>not</u> like Blake's RMF (mine was the same). There are some subtle differences but most importantly the routing and pipe sizing as well as collector design.

About the only thing they share is funky bends and "4-1".

Beware that Rage uses very thin steel, which is good for race setups, but you're at a higher risk of breakage.

You make it seem like if someone installed i/h/e on an OBD2 vehicle that hp/tq would stay the same.......thats not true at all. I've seen plenty of mild modded untuned OBD2 cars make more power than stock ones.......If this was true, than modding an untuned OBD1 car would net "0" results as well.
When we baselined my friends 5th gen, it made 173whp with i/h/e(about13-15whp more than a stock Prelude on the same dyno) and we were able to tune another 5whp peak and as much as ~20whp midrange out of it.....and that was with a $100 used vafc1.
OBD2 setups apparently hate adj cam gears though......

BTW: Kick in another $50 and buy a Vibrant....Dyno proven! Twice, by me!

I wouldn't be that surprised if the Kteller/Rage header could make more than a conventional design like the Jasmanian-Vibrant style. But I heard a whole lot of "cracking" stories about these.

 

While installing shelf headers and intakes and such can make more power for you, there are side-effects to not tuning.

Running either rich or lean at WOT is not good for an engine, and the stock o2 sensor setup is usually not enough to keep ratios straight in closed loop either. Using a VAFC should be able to straighten that out in most cases, but at the cost of screwing up ignition timing and risking further damages.

Shelf parts, fine. Don't go and put a big boy custom header on your h22 and think the p13 is going to have your car running right, because it won't.....and along with that goes the fact that if you overuse the VAFC to "tune" it out, you're either gonna lose a ton of power or risk detonation due to the bad effects it has on the ignition curve.

 

So an intake and cat-back exhaust would mess up my a/f ratio and cause damage if I didn't tune?

 

There are plenty of people who have driven around untuned i/h/e cars for hundreds of thousands of miles and have been just fine.

If you get some kind of ridiculous header or something along those lines, most likely you'll need a tune. With a DC, you'll be fine.

Look at the original post. His plan was to not tune at all. I'm not saying his motor is going to break if doesn't tune, but it's a serious waste of money to spend on all these mods if you can't afford to shell out another couple hundred for VAFC, Emanage, etc.

 

It's mainly for the sound and not the minimal gains I'll get. I might get it tuned later when I'm close to someone who knows what they're doing. I'll probably wait and see if vibrant comes out with their new design that fits the sh model and then get my car tuned. Thanks for all the help guys.

 

If your only looking for sound then just pick up a cheap crappy header off ebay for under $200. Its probably obvious, but what is/are atts?

 

The only time I noticed my header changing the exhaust note was when I was running on open primaries

 

I know a header doesn't change the sound, I was reffering to an intake and cat-bakc exhaust. I'll wait for vibrant and then get my car tuned. atts is what came on the SH model preludes and creates problems when trying to clear a header.

 

If you just want the sound why not go for the fart can?

 

^^ I hope you're kidding... if not well i'm just being realistic and know that the power gains from my cat-back and intake aren't noticable. No offense but does you're car even run?? By the way my buddy and I share the "wegotmorrison" profile at work.

 

DOOOOD. Just get tha DUAL CHROME MUFFLER TIP MANNN IT MAKES IT SOUND SOO BAD ***. EITHER THAT OR RUN OPEN HEADER MAN IT SOUNDS LIKE A RACE CAR.
