I was wanting to know if there is any reason the Buddy Club Spec II exhuast system wouldnt work on a 1989 Honda CRX SI (EF7 Chassis)? everywhere i look for them they say they either fit the EF9's or the EF8's and i personally am not aware of the difference from my EF7

 

If it could fits into an ef8,then it will not be an issue for ef7 as both share the same chassis except for the engine(ZC and B16A1).

 

alright, thats what i was lookin to hear, i appreciate it

 

FYI: your CRX Si is not EF7, it's ED9. Your car came with a D16A6 (basically SOHC ZC) and the EF7 is a CRX/Civic that came with the DOHC ZC.

You see these exhausts for EF8/EF9, those are the CRX and Civic SiR's, respectively. As greyrex said, the EF8 chassis is the same as yours (EF8 is still a CRX, nothing special about the exhaust dimensions), so it will fit.

 

sweet, alright man, i thought mine was an ef7 but i apprecaite it

 

Check your VIN--it's on the dash and firewall. the 4th, 5th, and 6th digits are your chassis code, e.g. 2HGED9 or JH4DC2.

 

i believed you, because i am completely in the learning stage of everything, but i checked and you are correct, i appreciate the help

 

i have a 5zegin exhaust off an ef9. it fits without modifacation if you use the shorter jdm cat. the exhaust piping is a few inches longer where it meets the cat.

 

where can i get ahold of the shorter JDM cat?

 

Does it have to be a JDM cat? Just check out eBay for different Cat's.

 

imma just get a JDM ITR cat from passwordJDM and it should work

 

Sounds expensive. Your probably better off using the money elsewhere.

 

that was just the first thing i came across that im positive will work, but ill keep researchin it till i get the exhaust

 

Im pretty sure they would all work, just match the sizes. Even if it's too big/ small the exhaust shop will be able to make it fit with flanges and suchwhats.

 

Yes it does actually have to be JDM....nothing else will do...

 

im not sure that cat is the same length as the ef8/9 cat. some of the after market cats are short. you just have to search around.

the easiest route would me to mod the piping on the exhaust near the cat. mock it up and see how much to cut off. if i remember correctly its only a few inches.

 

That's what was implied, but thanks for the addition.

 

Exactly. This is probably the cheapest method too.

 

i might just take the cat out completely and put a telescopic test pipe in its place? i dont want to mock up the buddy club exhaust.

 

I'm not running a cat. I'm still on the stock exhaust too.

 

It's because the bolt's on the flange are in a different pattern, well, same patern, but different positions, so they will not line up.

Go to a muffler shop and have them cut and re-weld. or have them make a "test-pipe" for you, just a straight pipe with 2 flanges, one to bolt up to the exhaust and one to the exhaust manifold.

 

bump

 

test pipe is an easy choice, if you dont mind not having a cat.

 

Stop bumping everyones thread to get your post count up, atleast try to give some knowledgable answer. That's like the 3rd time already...

 

i personally dont mind not having the cat, are there any major disadvantages to not having it at this point?
