The EX header will fit the head of the DX/LX, but you will need to get either an aftermarket cat or get an EX/Si cat.

I had a LX header on but the cat went bad, didn't realize junk yards didn't sell the exhaust manifolds with CAT's so I had to get the EX version...bolted right up...and now I have a metal rasp to my exhaust cause it's straight pipping....
Ah yes...how pretty that check engine light looks..
my bum is on the swedish!

yeah, the y7 headers are total crap. EVERYONE I have ever met with a y7 has or had this problem. If you have under 80k miles, honda will gladly fix it according to the recall, but alas, I didn't know until after the fact :upset:
actually, the y7s have two cats. Theres one in the header, and one under the car. There's two o2 sensors, as well. From my understanding (reliable source), the ex shit will bolt right on, and even if you have a hanging sensor (which you will if you do an ex swap), there shouldn't be any problems.
but then again, I've been driving with this header like this forever
h: I'm in no real hurry to fix it, really. But then again, I don't smell exhaust..... yet....

I found a crack in my manifold on my 95 EX when I was trying to get the O2 sensor out (which broke off by the way). Instead of wasting money on more stock parts, I decided to just spend $120 and get a Chikara header ( http://store.summitracing.com/partde...rt=HED%2D37030 ). Some say they perform no better than stock while others say you should see some small gains, but at the very least they weigh a lot less (like around 20+ lbs less) than the stock setup!

I think the Y7 only has one cat. The one in the header is the only one I can think of. The bulge under the car looks like a cat, but it's actually a resonator. The two sensors are standard on an OBD2 system. It takes a reading before the cat and one after the cat.
