uhhh....a cat's a cat. Any high flow 2.5" - 3" cat will work. Just might need to do something with your O2 sensor, depending on what year your truck is.

For an '00 4.7L the o2 sensor will hook up to the new cat. For the 01'-03' 4.7L the 3rd cat has no o2 sensor. Only the precats. Most people just cut the 3rd cat off and put a straight pipe in its place. Carsound makes a good cat. I have a 2.5" in/out and a magnaflow 2.5" in/out. This makes up my exhaust system. The rest of my pipes are stock.

You can still do a high flow cat -- if you have an O2 sensor to worry about, just get something like this:

KRC makes one, too, but it's about $10 more expensive.

Be carefull what you do. Cats are very strictly regulated by the emissions nazi's. Check with your local inspector before doing anything.

Good news - many states no longer use a sniffer on newer vehicles with the obdii port. Probably won't even check that unless there is a problem with the dash light. simms box would take care of that, you'd be good in MA.
