Here is a picture detailing the ground clearance on my EF with the JDM DC 4-1 headers. I have a B-series motor with the ha sport mounts. It hangs really low, about 3 inches below the cross member. Look at the box of cigs for reference

 

damn

what out for like a penny on the road

that would suck to bend them the have like2 sylenders cut out and not notice JK

 

My was about the same height if not a little lower. After 2 months the bottom 2 tubes were smashed in half. I put the stock header on and it flowed better.

 

why dont u guys weld a skidplate onto the primaries?????? it cannt be that expensive

 

dayam gina!!! did you have to cut your front crossmember at all to install? did it mate to the cat like the stock one did? and how bout the o2s? sorry for all the questions .

 

yes the crossmember had ot be notched slightly but it was pretty easy. not sure if its my car or how the hasport mounts sit but the headers angle up towards the car so i had custom piping to get it straightened out. as for o2's, i only needed 1 since i converted to obd1.

 

Yes, the crossmember has to be cut/smashed in. The O2 had to be relocated right before the collector and you'll have to have a different cat flanged welded on. I'd suggest getting a 2.5" high flow cat to replace the stock cat.

 

kewl..i already had a custom exhaust made for my stock b16 header with catco cat. noticable gains over stock?

 

Someone from HYBRID was making them.

I forgot the link since I don't use a JDM 4-1, but they are out there.

 

ya mine jdm dc 4-1 hang about that low.B16a with motor mounts made by the crower integra driver.I had a small skid plate welded an so far so good.I am plannin to sell this header for a jdm itr to get alittle more clearance.

 

eww, only homos smoke menthols? j/k. nice header. i heard from others that the hasport mounts point the header up, due to the new design (raised rear of motor for ground clearance). which is weird cuz the front of the header still hangs the same. but supposedly hasport is gonna redesign it again. it not just you, although mine dosent seem to do that. i need to look at it closer though.

your car gonna be ready for this weekend?

Yep, I got the same issue. Running the DC 4-1 99 Si headers. Even though I've been really careful & my car's not totally dumped, I smacked em once already. I think I'll change to the 4-2-1 1pc design for better front crossmember & ground clearance.

damn how lows your car cause mines dumped bout 4-5inches

 

cool, thanx for the link. And does the jdm itr really give more clearence??? I thought the dc was an exact copy of the jdm itr. And i am digging those skidplates.....nice!! I was going to purchase a dc, but now i am having second thoughts. Does anyone actually have the plates, and have some good things to say about it??????

yeah sure buddy.
let's see some pics of this 5" dumpage...

 

aye will those skid plates work on a ef hatch casue those are hella dope and i need to get one before i dent mine up any more...

 

i don't have any pics but it was just a guesstamation at about how low it is....it's prolly closer to 4.....i'm running neuspeed race springs with 2 coils cut, on a 91 4dr...i had a set of ground control coilovers that made it sit about 1.5-2 inches higher,and aren't those things supposed to drop ya about 3"....thats why the guess of 4-5"

 

my car isnt even that low, probbaly have a finger gap between tires and fenderwell.

 

those marlboros are 100s

 

i just bought a 4-1 header for my 89 hatch and you guys are making me worried now because my car is dropped 2.5" with tenzo springs. and i had problems hitting stuff without the header.

 

haha those arent 100's but it kinda does look like it from an angle

 

you guys think those skidplates will work with the DC header for the 99-00 si? Mine is getting scraped up too, and I would like to stop it before any more damage is incurred. I'm using the HASport mounts too. The 99-00 si header bolted right up to the cat, but I guess it's nowhere near as good as the jdm one?

 

I showed this picture before..

Fixed aluminium tie bar.. Saved my header (engine too)

 

That link says that the skidpads will ONLY work for JDM Type R headers...no other brand names such as DC, Mugen, etc etc will work. Is that true?
