my light is always on and i didnt removei it.

 

the cat might not give u a power gain (which i still think it woud give u a very very very very slight gain) but it will definantly make the exhaust louder

 

Why do you want the exhaust louder. Talk about being a poser. Might as well get some srt 4 stage 3 bages and stick all over the car. To make something louder just **** other people off. Grow the F*&k up. And if not you remember the crap you done when you are older and the loud BS pisses you off

 

ok im oretty sure i need to replace mine, i have a code 22 or watevr thats fpr the downstream o2 sensor, how do i replace it
i think i no where it is but ca smomone post pics
excuse the typing im itred and its dark

 

The downstream O2 sensor is just behind the cat converter. Unplug it, unscrew it and replace it.

 

im ogin to0 the yard tomorow
can i grab one form there
or should i get a new one?
and when im there i wanna get bl;asck carpeting for my car, will the 2nd gen carpeting fit directly to a 11st gen, i think so but wanna be sure

 

Will an o2 sensor cause your car to miss?
