It works!
Hey If you want Im sellin my EX header for cheap, all you have to do is get a mid pipe/cat from random technology and you'll see some gains.
PM me if you wanna buy.
if you search for topics on LX header, I'm sure you'll find something.
but here's a direct answer.
there aren't too many aftermarket header for the LX, the only one that comes to mind is the kamikaze.. I believe it includes a downpipe.
it replaces the lx's upper section header with the integrated cat convertor...
both of ex's o2 sensor is on the downpipe/cat convertor (they're welded together) one is right at the beginning of the pipping, where the collector starts, and the 2nd one is after the cat convertor.
you can do an exhaust swap from LX to EX by swapping out the entire LX's exhaust system, starting with the exhaust manifold (header) all the way to the muffler.
you'll be replacing with: ex upper section header, downpipe/cat convertor, cat-back exhuast. You can change any or all of those parts with aftermarket parts.
what you will need to do is just simply extend your o2 sensor lines...
the price for the swap isn't really worth the gains though. there will be some, but not enough to justify the cost.
for performance and value, I will recommend used ex upper section (or cheap ex aftermarket upper section header), random technology downpipe/cat convertor, and any aftermarket cat-back exhaust (suggestion: Apexi WS)
should be good for a 5-10 whp. thats a street-legal setup
HP race 4-1 race header with "highflow cat" and ex aftermarket cat-back should do a 5-15 whp gain. but you will need to invest in an o2 simulator since the cat will be gone.
thats a quick summary. I dont know how many times I've typed this up.
