Headers!!!!

Alright I know there were a few people who are wondering about which type of header to buy. Well i just put a megan racing 4-2-1 header on my 2001 honda prelude base type H22A motor and i got 9 horse power at the wheels. I paid 250 bucks for it which is a very reasonable price. Well just wanted to let you guys and gals know

Dyno sheet?
What are you tuned on?
What are your other mods?

Where did you get it? You can get them for $150 elsewhere...

Re: Headers!!!!

Probably didnt account for the rest of the exhaust, intake, and/or other mods prior to the header installation.

I'd like to see this proven though too.

Re: Headers!!!!

Das funny. Hahaha British Horsepower. Anyway to stay on topic, where's the proof for this?! I have had the Megan Header since I bought my car, so kinda curious to see what it does (if anything).

Re: Headers!!!!

Dyno is needed bro and a list of the rest of your mods, also you could've picked it up for 170 shipped all over ebay.

For now I'm going with Colin on this, but just like him i really do want you to prove me wrong cause 9 whp with just a Megan header, thats sick.

Also you sure its not a Mugen Header?lol for $250. Hey maybe some didn't know what they had.

Re: Headers!!!!

seriously that header is a dime a dozen on ebay...
would be sweet if this was for real but some engines are freaks and respond to some mods more than they should.

Re: Headers!!!!

Because generally, you don't see more than 3 or so, and sometimes you lose with them.
Depending on where you live, internet ftw, no taxes.

But yes, scan the graph so we can see it.

And smokey, the Megan, DC, etc. header is the exact same as the no name eBay headers.

Re: Headers!!!!

It's my job.

Lol, j/k. If it makes you feel any better, I had one on my H23. It's ore effective on those than the H22. Just look at the stock headers of each motor and you can see why.

nah he probably got 9whp after the tuning with the i-h-e combo. I doubt that a megan racing header alone will make 9 whp though.

Re: Headers!!!!

The power gain was after tuning everything. Hey if i didnt see this for myself i would be agreeing with all of you guys. I almost pissed myself when i saw what it made. I will try to find the dyno sheet and scan it and put it on to show you guys. Im telling you guys this is no BS but like i said you will only believe once you see the chart.

Re: Headers!!!!

alright so you just said it.. Its after tuning everything (i-h-e) that you made 9whp. I mean unless you did an intake+exhaust and tuned it and then you put the header on and tuned it and made 9whp after. Then I'll believe you.
