Do these H and X-pipes remove the cats or not? I am new to exhaust mods and am not familiar with these. I am trying to stay state inspection legal. Any help appreciated. Thanks

If it is an offroad h or x pipe then it has no cats and will not pass emissions. It will say offroad if it is. If it is a highflow h or x pipe it will have 2 instead of 4cats and pass emissions.
hope this helps

Thanks for the help. Do you know how they differ in sound. I am looking more for a low rumble more than the street racer sound.

I have neither aftermarket H nor X but in my research it seems the X gives a smoother exotic sound while the H gives more of a 60's musclecar rumble.
