I searched and can't find an answer. I have a JDM 4-1 header, testpipe, and es oval muffler. Running 2.5" all the way back. Anyone know what else is needed for this installation to fun smooth at the muffler shop? It's for a 92 cx.

 

a DC 4-1? or itr 4-1? the itr wont work on ur CX...

 

i have the same setup.

 

do u have a d15b8 in your cx or a b series motor?

the jdm 4-1 wont work unless you have a b series motor

 

NOt sure if you have the crx motor, but i have a 97'GSR and have the jdm header/test pipe bolted to my Apex exhaust! u just have to go over to Honda dealership and get the DOnut gasket for the s200 for its exhaust...real cheap dont worry!and thats it...just make sure test pipe size is same as both pipes on each side..

 

yea it has a B series, so all i need is a s2000 donut gasket. Sounds good, anyone with any other ideas or exp.?
