I recently added a Endless RPM J-pipe and XLR-8 HFC to my 4g SH-AWD. Today as I was driving home from work my check engine light came on and emissions system p0430 code appeared. Anyone got this code before on their 4g? I had put close to 150 miles on the new set up.

 

Had anyone had any CEL come on after installing a J-pipe (RV-6, XLR-8, OR ENDLESSRPM) on a TL SH-AWD?

 

I had light couple months ago. I believe it is HFPC to blame....

 

My car has stock cats, looks like something is up with my front car, hopefully its a false positive, I just disconnected my battery and reconnected it and the CEL went away, Hopefully it does not come back up, I would be really surprised if my cat went bad at only 62k

 

Burning oil?

 

I just checked this morning and Oil levels are fine. I think it was a false positive, I just remembered that I use to get a similar code on my 3G TL in colder weather.
