i just got my civic sedan and the guy before me had a stock manifold running to just a downpipe with no cat no nothing, runs to about center of car. My friend told me that ef sedan ( i have no clue about hatch,crx,wagons) have a manifold,exhaust downpipe that bolts up to just a small piece of pipe before u get to the cat. Im having trouble finding the exhaust piece i need so do i have any alternatives?..do the headers they make run to the cat?

 

just go on ebay get some full headers and a test pipe it will all bolt up with no problem unless u go to the junk yard and rip off a d-series

 

Are you trying to make it emissions-legal, or do you just want a complete exhaust system? If its the first one, you can probably find some stock exhaust parts in a junk yard or something and buy a new cat, which will probably need to be welded in. If you just want a complete performance exhaust, then yea get on eBay or something and decide how much you want to spend and go from there

 

im just trying to pass marta man. lol i have an exhaust with an cat i just need the rest of the downpipe stuff lol.
