GSR heders on civic with Ls motor

[Jayberg00]

I have honda civic ex 2dr, and my friend gave me a DC sport 4-2-1 header for a gsr, but i have a 96 b18b motor in my car and i was wondering if it would work but theres one problem, the heders that he gave me dont have a hole for the o2 senser can it bold up or it wont work at all. any help whould be great thanx

It will fit...
But from my understanding it will not meet up with the cat, because of different flanges...it will have to be modded.
(at least thats what I read for integras, it might work on your civic if you have a custom cat already...or a free moving flange)

An o2 bung will also have to be tapped into somewhere on the header....best place would probably be in the same place or similar to where the stock bung is on the honda header. Any machine or muffler shop can do that for you........even dumb midas cant screw that up (Id hope)

(header, not headers...you have 1)

i love that quote, we should make a honda parts for dummies book, we could make millions!

[pdiggitydogg]

only if you sold it outside the ticket booths to the new fast and furious movies

[AkimboStylee]

so we got a deal? i mean we could use c0ng0 b0ng0 as our reference!?

[pdiggitydogg]

now now

lets not get personal.

back on topic. it should fit, but i thought it had to be modified even on civics to fit the cat. after all it still an integra cat. you will have to make a o2 bung like pdig said. but i disagree about midas i think they would screw up.

[pdiggitydogg]

yeah...youre probably right...
theyd probably think the bung belongs facing horizontal instead of vertical, and they'd mount it on the edge of the flange so you have something to hold on to when you cart the header around

[AkimboStylee]

yeah that sounds about right, you got to have something to hold on to

[Jayberg00]

aight thanx im going to install it 2marow and take it to the shop for the o2 senser, you guys say that the flange has to be modded is the gsr flange differrent from the ls flange? i just dont wanna put the header on and drive to the shop with open header and puse i wanted to swap my hollowed cat for a performance cat. oh yeah my cat is the stock ex cat, so i cant just swich to a integ cat.

[IALuder]

so your getting a hi-flow cat? which one? i would make sure it fits both header and exhuast.

[pdiggitydogg]

yes, ls and gsr flanges and even cats themselves are different
