Need help with Check engine light not going off
 

I have a 2001 IS300 and I just put aftermarket headers, downpipe and exhaust on it along with all new O2 sensors. I reset the check engine light and it went off for a couple of days and now its back on all the time. Some one told me that I need to get a wire module to by pass the O2 sensors because its reconizing it as the converters are not there. Can anyone help me out with that and maybe tell me where I can find this module or any other suggestions I can do to get the light to go out. Thanks

ask any mechanic dear or search online
