Catted long tubes

Im thinking about buying some catted lond tubes for my ‘18. My question is i still want to be able to pass e-check, does all aftermarket tuning companies turn off the rear o2’s in the tune? Or is that just a lund thing

You will get varied responses on people that pass and fail emissions with LTs. if your state just makes sure that the cats are there you will be fine.

VMP will NOT turn off rear Os, apparently it is illegal to turn them off. I have a VMP tune right now with LT catted headers and have no CELs.

Just specify to your tuner that you want the rear o2 sensors left on in the tune.
