what is the best header to buy for a 2007 civic si sedan??

 

cant you even look around just a lil bit? damn dude.... there are countless threads about this already.
my vote is buddy club or bcrh for short

 

would the dc race header eliminate the catalytic converter??

 

yes.

 

since it eliminates the catalytic converter would the check engine light go on??

 

yes. but they have something out that clips on or replaces the sensor so that it doesnt come on. i forget what it is since i dont have a header yet.

 

its called a defouler

It fits. It comes pre-drilled so the SECONDARY O2 sensor just twists right in and the piece twists right into the race header pipe.

Before installing it make sure you have your battery disconnected so that it won't read a problem with the O2 sensor.

And make sure you put it onto the SECONDARY O2 sensor (the one on the horizontal portion of the pipe) since it is the one that needs to read a smaller amount of fuel mixture in order to prevent the CEL from being triggered.

I've had mine on for over a year now and haven't had a single CEL.

It works!

 

thanks for everything guys. you guys have helped me alot!!

 

yes it will. it fit in mine just fine.

 

are there any D.I.Y guides for instilation with the defouler? Im interested and would like to learn more

This is one of the only websites, noobs should be focusing on. Not only is it the official Mugen site for the US, but they have a lot of other 06+Si parts to. Oh PS if your not a total idiot you can call them an discuss any basic questions relative to a mod they sell. (Omni Power Titanium CEL Eliminator - Offroad Use Only )=$34.99
