Close but no cigar. I'll help you out.

 

Thank you sir!

 

Nice living room.

BTW cool header. When are you going to put it on?

 

Nice kitchen

Throw that header on and tell us how it feels yo.

 

i want to se dyno before and after!!!!!

 

I wish i still had my h22 so i could throw one of those on my ride. Looks nice.

Well I'm not sure when I will be able to put it in because I broke my clutch housing and I need to get another one. So untill I fix that I wont be able to try it out.

I will definately get a before and after dyno. As soon as I fix her I will be going to the dyno.

 

wooohooo. I hope I get mine soon!!!!

 

fastwanabe- let me know when you get yours, I probably wont be able to put mine on and test it until I get my car fixed. So let me know how it feels and if you plan on dyno tuning it I wana see your dyno numbers.

 

Do they offer them with a flange? I know most H22 headers that do not have the flexpipe on them, don't come with the flange because they're afraid that the H22 motor will move too much and break at the flange/cat area. However, with most mount kits these days (well, depending on who you go with), the motor movement of the H22A in the Civic/Integra engine bay is very little to no movement at all. On my old Hotshot header, it also came w/out a flange but I welded one on there and just bolted it to my cat and had zero problems with the header piping flexing or moving (there's no flex pipe on the Hotshot header either).

I found a deal on JUN H22 headers at a decent price through a distributor.... I'm planning on picking one of them up for my H22 and trying it out and seeing how it fit in the engine bay compared to my old Hotshot header. And the JUN header (from the pics that I've seen) doesn't have a flex pipeon it, but does have a flange.

 

Whats also nice about that header, is that it comes with an o2 bung I believe.

BTW nice kitty you got there.

They do offer a flange, I decided to go with out one because I will be changing my original exhaust.

Yes it comes with the o2 bung.

 

I'm glad that you like it. That is the new high temp silver powder coat. It is very new and Dupont is working on making it even better.

Here are the black ones getting baked from last week:


We will also be dyno testing the new header design against the factory manifold. Let me know how you dyno results come out. If you have a V-AFC, try lowering the VTEC engagement point after you put our header on.

 

The header looks really good. I can't wait for the dyno numbers comparing them to a stock mani.

What kind of flange do you guys use to bolt your header up to your exhaust(or cat for some of you) since there is no flex pipe? Do you guys just use a standard 3 bolt or do you use a two bolt flange that uses a donut gasket with spring bolts? I think the donut gasket with spring bolts would be ideal, allowing the header to flex and move with the torque of the motor.

Does the header cause vibration at all since it doesn't have a flex pipe and it is very long? I'm just wondering cuz the stock exhaust manifold and dcs and greddy headers have the flex pipe where it pass under the intake manifold, ideal to allow the motor to torque without putting stress on the header. Now I know B series headers are generally shorter, and instead of having a flex pipe there, they have a two bolt flange with a donut gasket. So I know the flex pipe location has a purpose, and i think also helps with vibration of the downpipe and exhaust travelling back up through the header.

I know when I had my greddy header modified by IB, they had the flex pipe removed and put a two bolt flange w/ a donut gasket on the end where it bolts up to the cat. Basically the downpipe was the same length as normal greddy header, but it was just a 2.5" pipe straight through w/ no flex pipe. When I put the header on, I noticed that I had a really bad vibration at around 1.8-2k rpms. I didn't have this before with the stock exhaust manifold and flex pipe. I speculate that the added vibration came from the downpipe amplifying the vibration from the engine because it was so long and didn't have the flex pipe, kinda like a tuning fork.
Also this header and most of the aftermarket ones don't have a bracket to secure the bottom half of the header to the block, like a stock exhaust manifold, dc, greddy, etc. have. Would that put added stress on the welds and the studs where is bolts up to the head, especially with all that vibration, and no flex pipe or joint?


Maybe I'm just analyzing everything to critically. I just hated that vibration when I took out my flex pipe. I ended up shortening the downpipe and made a flex joint w/ a donut gasket in the location where the flex pipe originally was. It looks basically like a B series header.


I really like the header though and for it price...

 

how much is it by the way?

 

Wow, made 13 more hp over the DC sports header! I have a HCP mount kit and I am considdering getting this header. Will I have any problems if I get this header with a 3 bolt flange bolted directly to my cat?

Thanks,
Jake

 

this may seem like a dumb question but why cant u use it on a h22 not in a dc or eg chassis. is it b/c of the front mount and bracket on the h22???

 

i saw pics on the site and i think i answered my own question, but it seems like the header hangs very low...

any clearnce issues?
