yeah there are workarounds the crush ring problem. (copper spray might work too) You can call DC and ask em. Maybe they are used on more comon headers, civic, teg, accord????

I read in a few posts after some 3geez forum scouring, that one or two people have used the OEM gaskets sucessfully. I'll definitely say that the OEM gaskets I ordered from the dealer are too big. But I may have recieved 2 gaskets from the single downpipe flange for the carb'd model, instead of the LXi like I ordered. The LXi rings are smaller, but that's due to having the stock 4-2-1 manifold.
so you recomend that i get some LXi gaskets? cuz im carb'd right now probably gonna do the efi conversion

not too sure where this thread is at, but I used oem style gaskets ( made by Rock Gasket) between head and header, and the downpipe did not use a gasket at all. DC header
hows it run roodoo? doesnt seem too difficult.
side note i havent heard from the guy so im getting a bit worried but then again he doenst seem to check his mail very often so thats kinda good for me to scrap up some money

It runs great, no leaks drips or errors. You can tell differences in sound, actualy is quieter towards the front of the car. Power increases come in stages throughout the rpm range. What plumbing you have after the header matters significantley. My set up is different than anyone else's here that I have read, I Have a two foot streight thru Smitthys (patriot) muffler in the middle of the car with 2.25 out the back and over the axle to a resonator tip
The gasket set I bought at the machine shop when I had the head worked was a Rock Gasket set, there was an exhaust flange gasket in there that worked just fine. I dont think the DC uses a gasket per say between the header and downpipe tubes.

that is a great idea
ch3wy, the crush ring is sort of an insert that goes in the downpipe section, most of the time it stays there so you may not need that. That is the reason they do not need a gasket between the upper header and the downpipe header
Guys, I just used the honda (EFI) crush gaskets for the DC Header I have. They worked just fine.

it will prepare u for mine lol
Do you have the part number? What year, make and model did you get?
I ordered part number: 18212-SA7-003
On Majestic Honda's website, it's part number 19864, which you'll see fits the 88 Accord LXi. This crush gasket is definitely too big for the DC header I have.
So my question is, if this is the same part number you used, is it possible that DC built 2 different headers?
that'd be major suckage. but i would definately like to know which one nswst8

I just went to the local honda dealer and got the set for a 89 LXi.
I have a set of DC sports crush gaskets I'll see if I can get to the honda dealer and compare them to the 89 LXi set. "No you can't have my spare set"

how much hp do you think this would give on a 3gee? about 7hp?
Go to the dealership. When I got my DC's, I needed both the crush rings and downpipe bolts. They had everything I needed in stock. The guys were really helpful and were intrigued by what I brought in

You'll feel the difference.
Better responce.

Yeah, I have the same gaskets. I asked the dealer for the 88LXi gaskets, which are the same as the 89LXi gaskets, I assume. I cross referenced mine on Majestic's website and they're indeed the LXi set.
The only explanation is that there are 2 sets of DC headers for the A20. Which explains why some of us are having problems and some of us aren't. Do the headers have part numbers on that little tag? I'm going to have to look it up again when I get home...
The ones in my header are not the same size as oem. I tried the 88-89 ones the 86-87 and buying two amd going to local exhaists shops. No dice it was an odd size. I never really needed them since the crush rings will not crush below the surface of the flange so no matter what they dont leak. Ive taken mine apart at least 25 times and no sealing problems. Which is good cause hunting down thosse odd sized rings would be a pain.
This is the exhaust gasket I will need and many of you guys probably need.
It goes to a Subaru Exhaust Gasket -Ex. Manifold to Block - 02+ WRX / 04+ STi or
Subaru Legacy 90-95
Cost me $20 at the dealership, and it had to be modified a little. It has about 6 layers of metalish stuff. GOOD SHIT! WELL WORTH THE MONEY!

Oooh nice work on the matchup! I went through a couple of books of gaskets trying to match one of those up too. Couldn't find anything, that's a great alternative to the crush gaskets.
Hey, no prob bob!
hmm some very interesting idea's i appreciate the input. that dude hasnt gotten back to me yet. so im just praying right now

Yes I think those that think they did not get any gains, still need some fine tuning. The header adds a percentage of gain to itself, with every percentage of gain from every other mod or tuning change you make. At least that is how I look at it anyway...
in other words it helps
