So I've been doing research on my cat / inspection problem and seems like this might help do the trick to get me through. Does anyone have any comments about it? I found his site, but seems as though ordering is down and his phone number is no longer valid. Is this guy still in business?

Thanks in advance!

 

I am not sure what your question is. If you are worried about passing a smog test, it depends. You will msot likely fail the test if the sniffer is working and your truck is not passing emissions standards. The only thing it will do is get rid of your check engine light.
