Rep Power: 349

I want to do my entire exhaust system but I have some questions.

I know how to search but I wanted general feedback from those that have put Si/Ex headers and exhaust on their Lx.

Here is what I want to do:

HP Header
Magnaflow Cat
GReddy Evo 2 cat back

what do I have to do custom?
will I run into problems with o2 sensors?
where do I put the o2 sensor...before and after the cat right?

Any general feedback and advice would be greatly appreciated, because I need to order these bad boys on the first week of Feb.

Thanks alot!

why not just get kamikaze header? it comes with the downpipe and highflow cat already if im not mistaken. the magnaflow cat is universal and doesnt come with the downpipe.

actually I think this is the one I was going to get so I won't need the high flow cat anymore...think it will work on my LX?

no, I'd just hook up the o2 sensors before and after the cat just like the US ex / CDN si

this wont pass California emissions........but I dont know in your area. We have a stupid visual test and nothing modified absolutely nothing will pass even if its carb certified for the EX and you added another cat.. Just way it works out here....
However there is always a crooked shop or two >.>, <.<.
I need that standford fabrication turbo CARB or I am going to by the new Turbonetics one for our car.
Access mag shows a turbo wide body civic by them that passed california emission standards. "cough"
cops just look for intercoolers and you need to pull out those papers even if it aint for the right model of your car. They 99 percent time will not know the differnce
