I just installed a JDM B18C into my 93 Civic Hatch.. DX. first of all i can't get a gasket that will fit from the cat to the downpipe. i bought one for a 94 GSR but it isn't big enough. is there something else i should be looking for and also is there any way to alter my cat so that i don't have to weld a piece from a integra onto it? thanks

 

i have a 92 cx with the cx collector pipe.. theres no cat there.. and the pipe is small i just shoved the downpipe into it with no exhaust o ring on it at all.. it kinda rattles a little ( not much ) but its there until i get the right shiet

 

which gasket should i use though?>
