I have a 2007 Honda Civic LX.

1) Will removing the cat throw a CEL?
2) Will a set of OEM '07+ Si rims/tires fit my car?

Thanks in advance; I'm trying to get some new ideas for my car.

yes to both....
if you take off the cat it will give you a CEL for shure...
and the si wheels will fit you car...
be careful'cause i believe the front ones are a little tricki when installing them...
make shure they clear the rotor and caliper....
but i think you'll be fine...

good luck

Cool...still debating the Si wheels thing though...just thought I'd ask.

As for the cat delete, I'm not too worried about it b/c the state I live in (Alabama) doesn't have emissions inspections yet. I just don't want to stare @ a CEL everytime I go for a drive. I read on another thread that a "de-fouler" would remedy this, but I followed the link on it & it said that it's for a '90-'00 Teg. But my thing is would it work w/my car if I put on the header I found for it & delete the cat?

its all universal. the one i had on my dcrh back in the day was supposed to be for an ek, but it worked fine for my fg2.

yeah the si stocks will fit

Exactly what benefit do you think there will be from removing the cat, other than the horrible smell?

1-2 hp? Can't be worth it...

See, the header I'm getting (Megan Racing) eliminates the cat. It will still tie to the exhaust I'm getting, also from Megan Racing.

I never thought about the smell, but again, not caring about emissions since Alabama doesn't require it yet.

Oh & a couple more questions...thanks for all your help so far people...

1) Will a '06+ Si rear wing spoiler fit my trunk lid without extreme modifications?
2) Has anyone used Mishimoto auto tranny coolers on their '06+ Civics? I'm thinking of getting one.

Dude, just go get an Si!

Sounds like you're talking about spending a decent chunk of change here...auto tranny coolers? Are you going to be driving an auto Civic that hard?

State emissions requirements aside, it's still a Federal crime to remove a catalytic converter.

Not that you'll ever get tagged, but I believe the penalties are rather harsh, and the gains are minimal.

I guess maybe I am a little confused. The thought the LX did not have a K-series motor and that the Exhaust Manifold was integraded into the head? I though you could not run a header, only a down pipe?

Just asking.

Thanks

Yes. 4 reasons why I don't want a Si...

1) I don't know how to drive a stick. Nobody ever taught me.
2) Even if I did know how to drive a stick, I don't want to hassle w/trying to find the "sweet spot" for a shift...automatics IMO are more consistent. I'm not building a race monster here; just an above-average street car.
3) Si's, as good as they are & as much as I like them, are WAAAY to common in my town. The closest thing to a modded R18 as of now is a Civic w/a fart can & a huge stereo. I want to top that & do something different than the norm.
4) Due to a couple of speeding tickets & citations for noise ordinance violations w/my last car ('94 Mercury Cougar), I can't afford the insurance for an Si; it would be as much as a monthly payment on it!!

Projected mods will be under $10k...I believe a '10 Si would be a bit more than that? I don't know.

& ChargedSI, yes, the LX does not have a K20 series engine; it has an R18 series. & yes, the exhaust manifold is intergrated into the head. But Megan Racing did create a header for the R18 engine, which is what I will be using. Or @ least they call it a header...it may be a downpipe; not sure. http://www.meganracing.com/products/...d=963&catid=67

Oh, & will using 93 octane hurt my engine? I'm currently running the recommended 87 octane. Thank you all for your help & answering my questions.

For r18 you should run on 87.

And no offense, but you don't want an Si because you cannot afford insurance, yet you are then going to drop $10k in modifications on your r18? Doesn't make much sense to me.
