He means you will need a tuner to remove the 2nd pair of 02 sensors. You might get a mil( malfunction indicator light) or its sometimes called a cel( check engine light)

And this may be the reason my O2 sensors weren't passing an inspection. So if you do tune your ride, make sure if you need to smog/pass an inspection, just reset to stock before you do it

Get whichever. I have the cats in mine. If you change you mind, you can always order the other and swap them in. The system bolts together with clamps.

You could always talk with Paul @ SW. He is a member here. Tell him your needs and I am sure he can recommend a product.

i have cats, and mine still sounds awesome. mine has quite a bit of rasp, and when it first starts in the morning, im pretty sure the whole neighborhood wakes up. if i dont remote start i try to sneak it in gear so people can sleep in! my truck sounds way better once its warm. not sure what causes that, but the sound has also gotten better with a few thousand miles.
