I was having some issues with mine running rough after start up and was told it might be a plugged converter. I took a dremel with cut off wheels and cut about a 2" square out of the side of the converter. Mine was hollow as can be, I get a little over 16 mpg. I took it and the piece I cut out to a local shop and he wire welded it back in for $25. Just be careful you don't mess up your front O2 sensor when cleaning it out. Although it will run if you unplug it.

From what I have read these converters were known to fall apart. I am not sure if mine was cleaned out or it blew out the back end. It had straight pipes on it when I bought it.

gutting the cat will help your performance but there are a few things that need to be done after to make it work properly.
1st - you need to disconnect the battery cable long enough to let the computer reset
2nd- install an O2 simulator or do the spark plug nonfouler trick to fool your computer that the cat system is still there and working correctly
3rd - my opinion is remove the cat gut it out and then reinstall do not cut holes in it. if you soak all the bolts with rust buster overnight it will work so much easier.
4th- this would be the perfect time to preform any kinda tune up and clean out your throttle body because the truck will be learning a new operating curve and you want everything working its best when it is doing this. IE new plugs, air filter, pvc valve, and wires if you have them
5th- when reinstalling use all new gaskets and then enjoy your newly reborn engine.

Mine did not have any clamps holding the exhaust together. Looks like the front part was factory crimped and the back is all welded. It was either cut a hole in it or cut the exhaust pipe to get to the inside of the cat.

I do agree you should clean out the throttle body. I used sea-foam through the brake booster vacuum line.

gas will not burn them out its a honey comb type material. if you can save it, the recycle place will pay top dollar for the material thats inside it!
