Just waiting to arrive my turbo XS downpipe+cat delete pipe,some guys told me that I need to install a O2 simulator to keep the check engine light off,where I can find these part???

Thanks in advance,

 

look in the how to section for instructions on how to make a mechanical one for $5 worth of stuff from pep boys or autozone. also, gruppe-s sells them in their exhaust section. i prefer the mechanical ones to the electronic since there is no wire hacking involved. it simply screws in in front of the sensor and your done.
