SMSP H22 Production Header
I really apologize for taking so long to get this to market, but it's really hard to work on prototype pieces while still trying to get current pieces built and out the door. The ITR Expo set me back also but the experience was well worth it.
Well this header isn't finished yet, but you should be able to get the idea. It's built to fit the cross member of the 4th and 5th gen cars. Since it has a 2-1/2" collector the cat will also need to be 2-1/2" and ANY cat back system will have to be modified to run this header so it is not a true "bolt on" piece.
It is a 4-2-1 design with stepped primaries. The tubing will be stainless steel. The flange material is yet to be determined due to the fact that I'm still not sure if the market wants to pay the extra for stainless steel flanges. The primaries finish at and the secondaries are larger than any off the shelf header that I am aware of. It will come in 4 pieces and shouldn't require removal or modification (still need to test fit though) of the cross member. The front engine mount will require removal during the install process, but the removal/install of that mount only consists of (3) bolts in the block and (1) through the mount.
If there is someone local (Corey doesn't count since his cross member is cut up) that could come by Saturday we could do a test fit and take some pics of the install. This would be greatly appreciated.
OK, you have to think upside down now.

The reason why the mount needs to be removed during install

Pricing: To follow later today. I'm looking at giving 2 pricing schedules. One will be for cold rolled steel flanges and the other will be for stainless flanges. However, all the headers in this first run will use either cold rolled steel or stainless steel flanges. The pricing will dictate how the customers would want to procede.

Re: cat placement & mount clearances
Looks very nice - 2 quick questions . . .
First, how much farther downstream will the catalytic converter be placed as compared to the OEM location?
And second, for those of us with the soft (and probably tired) OEM rubber mounts, is there any chance of contact between that #4 primary & the front mount on hard acceleration or shifts? It looks like it's close enough to the flange for it to not shift much, but it's hard to picture.
Eagerly awaiting pricing . . . .

Re: cat placement & mount clearances (Daemione)
I vote stainless flanges. Why spend a lot on a nice stainless header and then turn around and save a few bux on flanges that will rust?

Cat location: I can tell you Saturday if someone can come and do a test fit.
The front mount is bolted to the block so the clearance between #4 and the mount will stay the same.

Re: SMSP H22 Production Header (LudeAchris2001)
Any idea of the fitment of the header on an h22 powered accord? I know that the length of the header needs to be shortened to fit in the accord chassis. Any development in this area so we dont need to cut?

cut the exhaust not the header
if i didn't already have greddy header i would buy one

VERY interested.
If you need volunteer for anything, feel free to IM me as well.
Very glad to see this almost released!

How well does this header do on a relatively stock h22 (internals)?
Where does it move the powerband (RPM range) and does it negatively affect the daily driver rpm range (2000-4500)?
Should I even bother with this peice without higher compression/cams headwork?

Re: (ophdeheezy)
Guys, SEARCH..
Prototype #3/Dyno run 013 is the header design he is using.. Achieved just under 185 peak hp, w/ just an AEM, and Flywheel.. And the dyno pull was done w/ big heavy Race tires.. Most stock ludes dyno from 160-165hp.. With some tuning, watchout!
So no, you don't need hi-comp pistons, no, you don't need badass cams... If you do have either, certainly any other header won't do the trick like this one..

Re: SMSP H22 Production Header (SMSP)
I forgot how much I cut, but I had to shorten the h22a header quite a bit when I swapped it into my accord in order to fit onto the cat. Its not a big deal though, the exhaust can be shortened. Im just making sure that it can clear everything including the crossmember and all. I was going to get the hotshot 4-1 header but that only fits in the civic/h22 not accord/h22. Thats my only concern. But I definitely need a good header.

Well, your stock cat wont mate to this header, at all.. Your better off getting a carsound cat to go w/ it, to take advantage of the 2.5" piping, and then cutting/shortening your catback to fit.. Should fit an accord w/ no problems, since they are viturally identical in the front as a prelude..

I am familliar with the search, and that's why I don't even try on this site
Shoot, I misspelled my password this morning and my account on here got erased!
Seriously, though, I wasn't sure of the specs on that car in the original thread, and I would love to see a baseline comparison. Header looks great, and the pics in the original thread make me want it.
Stainless steel flanges aren't important- by the time it rusts out, emissions laws will have made gasoline cars illegal, so I should be ok. Other peeps who trip should just paint it first.
