Are the 94-97 EX exhaust manifold bolts(studs) compatible to the DX/LX/SE? Basically is the EX header gaskest the same for the non-VTEC's. I plan on getting Greddy Headers, but they are only available for EX's. I have a SE. The flanges are the same. Also you can install an EX's O2 sensor, which is longer, to reach the O2 outlet. I'm just not sure on the bolt patterns. Anybody have a LX/DX/SE with Greddy headers? Thanks.

 

i don't have Greddy headers and would suggest calling them for a better answer, but I will look in My helms when I arrive at home and believe it will work as far as bolting up

 

I called Greddy, they told me to find out if the bolt patterns are the same.

 

from what i can see the bolt pattern seems to be the same but there would be a conflicting problem with the O2 sensor and mounting brackets, you might have to buy a EX collector pipe

 

I'm buying a stock ex O2 sensor. Its twice as long,and will plug into non-EX's. The mounting brackets match up. All is clear except for the bolt pattern. I'm going to AutoZone later and compare the stock header gaskets for the different engines.

 

that is probably your best bet, I was judging my opinion by looking at :

I'll bet $ they are
