I was just wondering if anyone one of us in s.cali try that mod? is it worth it or it's better to buy a $400 high flow cat? I just order my B&B exhaust so i wanted to see if any of us did that mod and if you did, can you let me know the result.
thanks in advance. here the thread for it.

Gutting out your Catalytic Converter
1. Take off your cat.
Taking it off is very straightforward.
All you neet is to disconnect the oxygen sensor from the connector jst above it.
Unscrew three 14mm nuts on the front joint, two 14mm nuts on the back joint, detach the 2 horizontal support panels by unbolting 12 mm bolts that hold them in place (4 in each) and finally pulling off the rubber mount.
Even after you take off everything that holds your cat, the pipe will remain in place. To get it off grab a large screwdriver (carefully not to damage the metal ring in there) jam it between the flanges on the front join and using the screwdriver as a lever separate the joint. Once it is out, Just pull the whole pipe out of the rear joint.
2. Take out the Oxygen sensor:
Remove the sensor guard by unscrewing two 10mm nuts.
Unscrew and remove the sensor.
2. Gutting your cat.
Get a 11/2-2 foot long half 1/2" steel rod or something similar ( Home depot for about a buck ) and a hammer.
Flip the pipe vertically with the front (triangular flange facing up)
stick the rod inside the cat opening and using the hammer keep on whacking the internals until the rod breaks through. The is made of 2 parts, meaning that there are actually 2 elements inside that pipe, so when you break the first one, shake the pieces out, and continue whacking on it and shaking stuff out until there is nothing left. Use a light to see inside to make sure that it is empty. When everything is out, you'll see that the inside walls of that (now just resonator) are relatively clear and there is nothing left.
This is it. Now you are a proud owner of a completely stock looking catless midpipe
Reinstall the sensor, and put everything back following the directions above in reverse.
Happy modding.
