Header, Intake, & Exhaust - Need Help

In my endless search to find after market parts for my new 04 coupe, I have found that as far as exhaust products go,(headers, cats, ETC...) these parts are only made for the ex models and not the lx. Will this make a difference and will these products marked for ex fit an lx?

I dont think they will fit since your LX is a non-VTEC.

Try yahoo's search thing. Found this on my first try:</P>


Greddy SP2 Exhaust</P>

So the VTEC has a totally different engine block than the LX?</P>

yeah

I have a 98 LX......My friend has a 97 EX. This is the deal (if the 04's are the same). </P>


You can use EX parts with slight mods. I have a complete EX exhaust setup (DC headersand Thermal stainless cat back) but it means changing to the EX cat (everything bolts up). </P>


Intakes will require either finding LX parts or converting to an EX manifold which will costsome loot. </P>

damn thats simplke enough for the exhaust

i know nothing of the 04......however i do know that 88-00 bolt on parts are interchangable with few mods.

Okay, that will work for me. I'll let you guys know how things go. If you guys get anymore input let me know.<IMG src=smileys/smiley2.gif border="0">

I had a 2003 Civic Lx but i had bought an 03 EX intake there is a difference between the LX and the EX in size of the intake on how long it is. I had to cut a portion if the intake to make it fit on my 03 because of where the trans was and from where the end of the intake stopped at. I hope that this helps you in a way and i hope that this makes sense. GOOD LUCK

All the research that I have done has shown me that the lx and ex do have different engine code numbers, other than that the only thing that I can see thatis different is the valve train. As far as engine block size they are both still the same 4 cyl. So in theory, I think that an ex part will fit an lx. As far as clearance for the header itself, I'm not really sure. Does this make sense to anybody else?

More than likley the EX part will fit. The intake and exhaust head ports are more than likley the same size. If you have any doubt, call a good shop in your area and tell them your thinking about buying headers but you just want to be sure they'll fit.
