Will the aftermarket header fit without getting a exhaust system? i have an LX
Yes, you can get an aftermarket LX header and it'll bolt to your stock LX exhaust just fine.
What you CANT do is get an EX header and expect it to bolt to your LX exhaust, because they wont even be close- the stock exhaust will be too long... you could take it to an exhaust shop and have them cut a few inches out your LX exhaust and re-weld it so it bolts up---- but I dont suggest it, you'll still have a pea shooter exhaust.
Hey guys im new to this site but i stumbled across this thread on google....
I have a 2004 Honda Civic DX and i was searching for headers and catback exhaust..but i found a combo at a cheap price..
my question is...can i put these EX parts on my DX with no trouble?
if so what do i need to do
and also these parts are from ebay
thanks
I refer you back to the first post. The DX and LX exhaust are exactly the same. EXACTLY. So whenever you see LX in an exhaust thread, just substitute DX and i'll all make sense for your ride.
EX parts will bolt up just fine, but you have to convert your HEADER, DOWN PIPE, CATBACK + MUFFLER to run the parts. If any of these parts are from a DX/LX, then it wont work without having custom work down at the muffler shop. What kinda custom work you might ask- depends on the parts your talking about swapping. Post some specifics and I'll get back 2 U.
hey, so i got back from vacation, got the header all cleaned and ready to go (had to do some work since it was a used HP racing 4-1 header) and made the attempt to install it. once i took out the bolts they had included and spraying them down a few times with wd-40, they actually cleaned right up for the most part, and so did all the threads on the header itself. i decided to just see what would happen by using them instead of drilling a bigger hole, getting new nuts, bolts, washers, and tack welding the nut on the top. the hp header bolts/springs are the identical ones to stock, so i actually used the stock ones since they were in better condition on the new header.
anyway, after i got the stock header off with some annoyance from that stupid a/c line being in the way, i went to install the hp header. everything fit in place, i put some anti-sieze on the threads and everything bolted right up. everything went smooth except for when i was under the car and went to thread the two bolts in that connect the downpipe. the passenger side one went in and went nice and tight, but when i went to do the driver side one...it tightened snug and then slipped. i would do 2-3 more turns as it snugged up then it would slip again. i think one of the threads is worn on the header hole. do you think theres anything i can do to make it all tight? last thing i want to do now is remove the header, drill them out, and rethread or use a new nut and bolt.
do you think i can just thread new nuts downward onto the bolts from the top side until they are fairly tight, then get back under the car and torque the bolts into those new nuts? i know its the threads on the one hole of the header, not the threads on the bolt that are the problem...
Rocky, you're going to want to drill the hole in the header out before putting on the new nuts. Otherwise you run a risk of stripping out the bolt as well by having essentially one really long nut (combo of both sets of threads) that is partially stripped.

There's a good chance that I'm not going to answer your PM.
ok i never thought of it that way but that makes perfect sense. so in other words if i leave it as it is and try to put a new nut on... im going to be basically threading the bolt through a double length nut with part of the threads already stripped and that potentially can ruin the bolt and i would have a total headache trying to fix it at that point.
well, like i was saying before, everything is tight and secure and ive been driving on it since wednesday without noticing any problem at all. one bolt is completely torqued tight, and the stripped one is tight enough that it only slips when i go to torque it real tight. it never slips to the point its loose, just to the point where its not torqued all the way tight which im thinking i can live with.
we (www.em2ab.com) are going on a cruise tomorrow to banff so i will check it when i get back and if it is leak/problem free, im going to leave it as it is otherwise ill take it out, drill it out and use a nut and bolt like you guys suggest.
So, just to clarify, I have an '02 LX. If I buy an aftermarket or stock EX header, and the Magnaflow exhaust I want( this fits EX or LX because it has an extension pipe to hook up to the LX manifold). With the extension pipe on the exhaust will be too long, but without it it will be too short because it will be missing the EX downpipe and converter, right? This magnaflow kit also comes with a 3 bolt flange to hook up to the EX downpipe, so can I just have the extension pipe cut shorter and the 3bolt flange welded on so it will hook up to the EX header? Or should I just get a 2 piece race header, this should bolt right up to the a/m exhaust w/out a converter right?
I was also wondering if you had any opinion on whether ceramic or stainless is better? I heard that ceramic will run a lot cooler, but which one will last the longest?

You can run the LX header and EX exhaust perfectly fine as long as you have that extension/converter pipe that comes with the exhaust. You could also buy an EX race header and it would bolt right up to the exhaust as well without any extension pipe. Your other option should be a stock EX header AND downpipe.
