I have a check engine light and the code reads "Typically caused by the wrong O2 sensors in the wrong downpipe or a major exhaust leak. Grey wire loon goes to the back pipe, black wire loom goes to the front pipe".

My current set up is VRSF catless downpipes with a COBB catback. I have a JB4 installed, the Downpipe fix from VRSF, and I also have O2 simulators.

I'm wondering if anybody can recommend what I might need to fix, the o2 simulators... the downpipe fix... maybe an exhaust leak?

I need to get inspected (well... as of December...) and I haven't been driving it as I'm a student in Boston, but any help would be appreciated.

Aren't the downpipe fix and O2 simulators redundant? That may be part of it, but I've never used either so it's hard to say for sure.

You're probably having conflicting codes between the downpipe fix and o2 sims. Plus you're not suppose to run the fix full time either.

Why on earth do you have O2 sims on this car? DPfix isn't supposed to be a permanent mod. Only temp for inspections.

Sell JB4, reinstall OEM O2s, sell DP fix and O2 sims and grab MHD. Won't have to worry about inspections anymore.
