truckertony,
Removing the cats will only cause you problems with your truck, and I don't care where you live, emissions inspections are coming to where you are. It's also illegal to remove a functioning cat from any vehicle driven on the road. Unless you are racing only, I would leave them or go to some high flow cats that are available from many aftermarket companies. The gains to your street driven truck will be so small if any , you would have to have a dyno to tell it. Please don't invite trouble to come, it'll show up enough on it's own.Just my .02$ Merry Christmas!

Did you just want to change the CATs' because of the popping noises? or is it because you are having other problems with the engine? You may have water falling on top of the CATs from the A/C. I would mention that I have done the removal and noticed a drop in power, not to mention the extra noise out the exhaust. I had a local muffler shop install universal type CATs (one on each side) and my truck runs great. The reason I did not install the original type CATs was because they cost around $2000.00 where I only paid around $250.00 for the 2 universal types...
