Re: NJ people with Downpipes? (mpdbrown)
I run the Ferrita 3" DP.
I used to throw a code for the second o2 sensor. I drove with a check engine light for 6+ months. I added the IPD spacer for the o2 sesnsor and the code and lights went away.
I don't have to go through inspection until 1/2011. I am not sure that I will pass at the DMV, but I will bring it to one of my friends shops that will pass me.
If you are thinking of running one I wouldn't worry about passing emmisions. There are places to bring it.
