Headers Mod / o2 Sensor

Hi every one,

I'm currently looking to change my Headers, "Y" pipe and Exhaust. I'm looking for a complete solution that avoid that ... yellow, check engine, light to light up.

At this point I've found the Magnaflow headers that seem to dose it right. But before investing ±1000$ for the kit, I would like to know if some of you has experienced these headers?

I'm also wondering if some one know exactly how work those o2 sensor? is it only about the Co2 ratio or does it take the level of back pressure ...

(I saw 2 converters on both side with one sensor before and the other between the converters, so if I cut off the second converter it should not affect the air/fuel ratio?)

Thanks for your help.

 

Underdog Racing Development sells o2 sensor simulators, left hand side of the page under o2 simulators

Acdronin nailed it. Check out URD! Everyone seems to prefer the Doug Thorley headers and you can get the O2 sim with them to prevent the CEL from lighting up.

 

kk, Thank you guys, I will probably go with that option.

Did you guys had a converter on your "Y" pipe. I've have been told by my local dealer that we need it to make some back pressure for the engine?

Or maybe it's better to use short headers and fit converter on them with a straight "Y" pipe?

Or no converter at all?

thanks

 

I have the DTLT and remove the front set of cats. I relocated the O2s. If you need to have an emission test done you will need a set of cats.
