High flows have less of a restriction than regulars

Removing cats is illegal.
If you have a state inspection, they will fail visual and sniffer emissions check. They will also throw codes on a vortec.

If you don't have inspection, or just have a visual check, install dummy cats. I will be using dummies, since I bought my truck with no cats.

You can get away with no cats or high flows on a vortec if you run some spark plug non foulers on the rear o2 sensors.

The cops can still ticket you if they pull you over for loud exhaust. I suggest 2 of these like I will be running
