ok guys i've done some searching and can't find the answer to my problem. I've got a 93 lx w/ a 4-1 exhaust manifold and downpipe. the flex is all messed up and there is no exhaust after that. on my parts car (91 ex) has the full exhaust underneath it, but no motor or manifold, just the down pipe still connected to the flex and the rest of the exhaust, the manifold set up on it was 4-2-1. i was wondering if my down pipe off the 4-2-1 set up would bolt up to the 4-1 manifold, or am I going to have to find a 4-2-1 manifold to bolt up to my down pipe? anybody know. i'm gonna guess and say no, but w/ honda and their interchanging parts ya never know what will go w/ what.

 

no, you'll need the matching exhaust manifold to bolt up to the downpipe.

you can see in the following diagram the difference between the two downpipes and why you need the matching manifold.

 

that's what i thought, thanks for the info man

 

yep, no problem
