i have a 2001 civic ex coupe 5spd. i am going to buy a shorty header for it or whatever u call it. will it fit on the stock downpipe. i think the outlet for the header is 2.25". do i need to get one with spot to put the o2 sensor also. heres a link to one i would get. Ebay header or this one ebay header 2 if both of these r good, which one is better to buy

i dought the stock downpipe will fit. if i were you I would go ahead and order meganracing down pipe and the header the sametime. Just to be on the safe side. And also I dont think those cheap no brander ebay header will give you any power. Just lettin you know that it is a waste of money.

hp racing also makes a full race header for EX models.
its the top portion header connected with a downpipe as well. thats your best bet if you have an 01+ ex model. rumors has it that you have to shave off part of your motor mount or tranny mount for the manual owners.


as for bolting on a aftermarket header with factory downpipe, yes it is possible. i had no expierence with installing headers, but i did have a hard time bolting on my megan downpipe/test pipe with my OEM EX header. im auto btw
