im finally gonna get my car back and running and im going ls this time. it has stock header and i have a greddy evo catback. i cant run a test pipe yet cuz i have to go pretty much straight to the ref cuz i gotta smog my car in october so what do i do about a cat? do i have to go to an exhaust shop and have it extended or can i a stock cat and have it bolt up with out any problem?

also which radiator hose would i use for a civic half size radiator?

 

use a 94-95 cat converter and the 94-95 upper hose and bottom also. Um what model is the eg? mine is a VX and I had to swapp out my fuel pump. well I think it was just bad. But yea and you gotta repin the o2 sensor to a 4 plug. I still have to do that.

What I did was just bought a hi flow "fake" cat from ebay for like 30 bucks. I'm looking for a stock one cuz the hi flow is too damn loud and illegal. anyone has an offer?

 

i have an ex so i dont gotta worry about that ****

 

any b motor radiator hose will work

 

great but what about the cat?

i had a ls swap in my coupe before

i used the stock cat from the ls

the swap came with dc headers

so with the dc headers and a oem ls cat i still used my thermal exhaust

 

Provided your exhaust didnt move location of the stock cat then it should bolt right up and you should be fine with the ref. I used my stock cat and passed.

 

the stock cat from my car or the ls?

 

Why don't you just buy it for a ls motor cause that's what you have, makes sense right?

 

well im getting it swapped in tomorrow so ill have both cats but from what i understand the ls cat on stock headers will come up like 2 inches short of the catback and i have a greddy evo

 

it shouldnt because why would they make a aftermarket header that is 2'' shorter than an oem one? does not make much sense ha?

i know the gsr one is shorter than the LS could possibkle have the wrong manifold?

as long as you have a LS manifold on your LS motor with a LS cat then you should be fine cause you said you had a ex correct?

 

so an ls cat will work without extending it or anything? yea i have an ex

yea it will bolt right up

 

what about a gsr cat? will that work too? my friend said any teg cat should work but then i read on here the gsr is shorter. stock ls header

 

just use the ls cat, trust me it will fit. when i did my ls swap i still had the dx stock exhaust system and it fit

 

i donno if GSR stcok header are different than the sotck LS but .. mine bolted up to a stock DX cat ... unless my cat is from an EX

 

im just having trouble finding an ls cat but so far ive found like 4 gsr cats, thats y i asked

 

well my car passes emissions with the stock header and exhuast if thats what you mean
