Yeah I was there when they tuned it and they told me that they did not tune out the rear
02 sensors.The metal core cats work.

The issue with tuning out the sensors through trifecta is that it will show as "unsupported" in the OBDII readiness scan. In states like MA and many others, having more than one "unsupported" will get you flagged and require you to have your inspection done at a state MAC. I think (could be mistaken) this is unlike IPF, which tunes it out but has it show as "ready".

Could you not get the shop to take the stock cats, and use them on your long tubes? Wouldn't that work, and not throw codes?

I'm liking the OBX LT header set up but am also looking to add high flow cats around the time I purchase. Anybody know if the Pypes 2.5" high flow mini cats without the midpipe set up would fit the OBX LT system instead of their included test pipes?
