Maybe someone can answer me but why does dc sport offer a axle back, and they offer a cat-back but for the cat back to work you need a dc sport race header? is there anyway to get around the race header? i always get a check engine light when i installed a race header on my ep3 and i hated that damn light. or is there a way to bypass the check engine light with the headers hopefully someone will have the answer to my questions.

As far as the cel for the ep3, to avoid getting a cel you have to purchase a Casper's o2 sim (PN 104053). I don't really know if the same applies to the Fg. I'll look into it further and get back to you. :)

Exactly what 2fast4u2 said, a caspor 02 sim. In terms of offering an axle back, DC only has the full catback that has to work with the header. It will throw a CEL but the casper sim on the motor should solve that (k20z3)

I believe that the setup gets rid of your cat. By doing this you can have the local shop, cut and weld it in. Or in true bolt on fashion, get the matching headers and open the wallet. Be prepared to see some black smoke from time to time, w/o the cat.

depending on how the ecu is on the civic, the o2 sims may be to slow to fool the ecu if its similar to that of the RSX

I just added a DC Sports axle back to my 07 Si sedan. It is the only mod I have done so far and my CEL went on less than a week after. Is there any way that the two could be related? Doesn't seem like it but I'm kinda buggin that my car with less than 800 miles has a check engine light on. Any thoughts?
