The cat can just unbolt. Get a broom handle and break up the honeycomb inside the cat. Sometimes you need a bit of force to get it to start breaking up. Once you have emptied the cat, bolt it back on. Now you will have a straight thru cat and lots more rumble, and wont cost you a cent until you get caught poluting.

The o2 sensors wont be affected either.

Re: cat removal help
If you empty the cat it is worth nothing.

its not rocket science, just beat on it till its not there any more (from the inside with the aforementioned broom handle or other hard, long object. It can be difficult to break down. *edit* for clarification, the best way to ensure everything is gone is to have the cat completely removed from the vehicle where you can dump it out.

Also you will likely get a dtc for catalyst operation. There are options but I am on the side of the market that fixes these problems, not the side that jury rigs them. You do have options to try, google is your friend ;)

Re: cat removal help
if you want it to rumble, just run straight pipe after the cat and lose the resonator/muffler. no need to remove the cat just for noise, its the resonator that quiets it down.

Re: cat removal help
And why do you want to remove the CAT? There are no performance advantages. If you want more noise, I can see that, but it's an I6 for god sake. What do you think it will sound like with a straight pipe? Not that great. If you want to wack the guts, take these guys suggestions. Personally, leave it alone if it's working.
