im curious cause i bought me a 1pc dc headers for my 1990 integra 2dr.
im wondring if it will fit right.... or if i have to modify things? thanks.

 

they might not hook directly up to your exhaust if they arent made for your car...

as long as they are for a bseries motor they will bolt to your head..

they just hang low..

 

so then i have to get my exhaust modified?

 

you also have to look and see if it'll clear the crossmember. because DA's have a crossmember that make it hard to fit some headers. unless you get an aftermarket one. i don't know what companies make them, but i know if you get an aftermarket one, it'll clear some room.

 

as mentioned above... depending on which car the header is made for, you may have to get your exhaust modified.

as for the crossmember, you will have to notch your crossmemeber IF it is a 4-1 style header... if its a 4-2-1 then notching is not required.

 

i got a 4-2-1 1pc. so then it will ft right in? or are you talking about the 2pc.... but either way i still have to modify my exhuast right? or is it either just the crossmember or the exhaust.

 

If you bought one specifically for a 1990-91 Integra, you won't need to modify anything. A 4-2-1 1 piece will fit fine, although it is hard to fit and you may need to loosen or remove a couple of fan bolts to wiggle it into place. Otherwise, because it's 4-2-1, you don't need to notch the crossmember, and if it has the o2 in the correct location (on the 90-91 it is on the left most runner of the header), you will be good to go and you won't need to modify your cat flange or exhaust either. If it's for a 92-93 Integra, it will bolt up to the head and to the cat, but your o2 will be in the wrong place (you will need extra wire to get the o2 wire to stretch to the o2 location in the collector that the 92-93 uses).

 

oh ok! thanks guys... i think that was enough help... but more help is welcome!

thanks,
Luck
