Cats are the question

[jsbihn]

hey all,
i have the crappy cat thing going on.
basically the truck sounds like someone shaking a krylon can when it is running.
So I am wondering where the actual cats are on the truck

I am not stupid when it comes to vehicles, but I have found out from other vehicles that sometimes there are multiple cats or what might look like a cat is really a small muffler or a resonator.

So i would like to know where are all the cats are at on the truck, and if possible pictures would be great!
Thanks

BTW, do you happen to know the diameter of the pipe leading into and exiting out of the cats?

And have you heard of anyone who has eliminated there cats, and if so did it effect anything and is there anything in addition to the cats being eliminated that has to be done (ie. like for the o2 sensors or any check engine lights)
