jdmturtleracin, I've said what I've felt necessary to say about the product in response to statements made. And yes I've seen many headers in person, including ones just like this one. And where a part is made does many times determine its quality (Quality Control). You do get what you pay for. If you have any further to say to me personally please take it to PM. I don't want to crap up this thread.

Well,
I have received my header from Deloboz in TX, ordered from Topspeed (Ebay). So far everything is as promised. Overall its a pretty good looking piece.
My one point of concern is the porting at the header - engineblock interface: two of the ports look like the tube was not lined up right when welded, and no real attempt was made to smooth the area. If it was my shop, Quality Control would have tossed this one. I will call them and see if they want to do a swap...otherwise I will install it and dyno...will probably be fine.
Pics of the issue tonight...late for work...

Installing one on Tuesday, along with several other mods. I can post my reaction, but I'm not going to dyno until after my ecu gets back from Hondata (and I haven't sent it out yet, labels on the way).

interesting, but not unexpected as i mentioned a couple pages back. It may be possible to grind/sand it smooth, i had to do so on my MR test pipe.
as mentioned before, the nice thing about the DC header is the ports on the cylinder head flange is they are exactly the correct and matching oval shape and smoother on the inside than even the stock manifold.

yea I see that the DC can now be had for ~250 on ebay...I think I would have gone that route were I paying attention. Somehow I found the chinese knock off, and a low cost Typhoon, but never looked for the DC...so didn't realize that for $50 to $70 more I could have the real deal. I now accept my place as a guinea pig.
sad thing is I have a tiny exhaust leak that need fixing..for the last two weeks, I have scheduled the fix and then been called out of town for work...that is happening again this week...so I am out to at least next week to have the exhaust fixed, then do a baseline dyno, then a week probably to get the header installed and re-dyno.
Good news is I stumbled onto the fact that the owner of the performance / tuning shop I was going to use lives next door...hopefully useful...

Looks like I'm not going to have mine installed today afterall. I dropped my car off at a shop this morning only for them to do nothing with it. When I called this afternoon they quoted me an INSANE amount of money (I'm having pulleys installed too) so I told em to blow me and I will have to find another place.
I can do the header install myself (and cat) but the pulleys are a no-go. I'll prolly put it on now at the next DC-area install meet, which looks to be 2-3 weeks away. Since I'll be doing them at different times now, I should have a better idea of the effect of just the header (and cat).

WECoyote did report that the header ports are not perfectly aligned unlike the DC sport headers, DC are also $100 more according to Ebay prices. So far from the butt dyno of previous 2 owners, everything seems to be positive and nothing negative yet...
I know I will be going with these headers instead of DC and save the extra $100 toward the UR Pulley fund

For Record:
Header not installed yet
Leak is somewhere in stock, 3 year old exhaust
Header decent quality for price, looks like shiny DC ;-)
Header also has quality problem, 2 of the "down tubes" do not line up with weld point at the engine block interface creating "turbulent" surface
Hope to fix exhaust this week
Hope to dyno next week (11th)
Hope to install Header and dyno week after (18th)
Performance of this part is not verified yet...can't wait to see!
Sorry for all of the delays, but I have a new job that has me travelling quite a bit...and allows me to order TSX mods with wreckless abandon ;-)...on order: K&N CAI, new OEM floor mats, interior blue LEDs, hondata and pulleys in future months....

would you mind taking a few pictures of that down tubes not lining up ?

If they are 'off' on yours, how do you fix this?
What about taking a dremel sanding wheel to it? If you were to do this, what would you have to do in ways of picking up the dust left behind? One or two of the inside edges of my header are a little rough (in the piping). I know it prolly doesn't matter but I was considering sanding them before install.

a picture is worth a thousand words
you can sand/grind it down with a dremel, just make sure you wipe it all up afterwards. To throughly clean out the tubes, you can get a small, damp rag and just push it through the piping.
Since it's an exhaust manifold, very little particulate will get back into the engine anyways. You might clog the cat if you don't clean up after sanding, but otherwise there is no catastrophic damage issue.

i just purchased this header as well. I'll take pics and post them later. I'm curious to see if this "not lining up" is the same issue you are refferring to.

My pipes all line up quite fine, thankfully. I even posted some pics in a thread in the pic forum. Now, in the 4-to-2 collector area, the insides where the pipes meet are pretty sharp actually, and I was thinking some debris or shavings might come off over time, and to prevent any of that from going thru the cat and keeping things as nice as possible, I'd grind those areas lightly pre-install.
Just wondering if this was a bonkers idea. Sounds like it shouldn't hurt it though.

Hmm....I wonder if you should sand that part down. You don't want that part sticking out and preventing the top of the header from sitting flush with the exhaust manifold.

Here's a pic of mine (I really don't have any problems with it other than the rough inner edges).
Quality control be damned if this thing dynos well for me.
Lastly, the one with the rough edges I'll tackle:
