no. it does not add 10-15. it's really like 2-3. as for fitting, give us the sizing of the header first

DC-S = DC Style Header. Off brand Ebay header. I have one, there is a little gain, some tone difference too. Your secondary o2 sensor will need to be extended, and to get your CEL off you will need to get an o2 simulator. www.o2simulator.com < if you wannna know more. Also, the flange of my stock exhaust didn't fit that of the header, so i had to bring it into a shop to get a custom flange welded on there. Real quick and cheap fix, but stillnot very convenient. I do beleive this will remove your catalytic converteras well (considernig the cat of the 99 LX/DX is right in the exhaust manifold, so this header will remove it). If you want to stay eco-friendly, get a highflow cat and have it welded somewhere in your exhaust, but if not your cat will be gone. Hopefullly you dont live in a state where they test for emissions (if you decide to leave it off). People say they crack over time, and i wouldnt doubt it, but so far mine been all good. Looks real nice too so GL with the install and eveyrthing

I'm probably the only person on here that put in a header in a DX/HX/LX (All have Cat in the exhaust manifold), did the o2 Sensor extension myself, drive around without a cat and not get a check engine light or have a smell from the exhaust because of no cat. Even when I went to get my car inspected the guys were amazed that I didn't get a check Engine light. Before I went to get my car inspected though I did have a Magnaflow High Flow cat welded onto custom piping with my Twin Loop Muffler. You can either do the header now and wait to put in the exhaust/cat on like I did or put the header and exhaust on at the same time, then have a cat welded onto the exhaust piping.

^ thats crazy you didnt get a CEL, i envy you man

also, you can get a highflow cat, and then a catback exhaust from a d16y8 and it will fit up perfectly (length-wise with the cat and the catback).
