I have a couple of broken studs on my 08. I have no leaks at this time, but was considering headers on replacement as well.
Can u eliminate the cats with free flow cats or just pipe? and if so, will it still run the same? I only have 120K wonderful miles on this Awesome Truck.

Ever walk near a running vehicle without the catalytic converters? Stinks to high hell, especially if there's ethanol in the gas.

The 3-valve is fully OBD-II compliant, so there are O2 sensors after the catalytic converters. It'll throw a code if you remove the cats. You can tune around that, but why would you want to?

I don't know why, but people report different results when they gut or remove the cat. From loss of low-end torque to "it's great!" - I don't know why. I've heard bad things especially about the 3-valve. It's tuned intake and exhaust seem to like to stab people in the back if they are screwed with.
In my mind, I'd rather not take the risk of getting pulled over on the highway by some State Trooper who has a ******** for checking emissions equipment.
Back in the day, like the 70's, when they were just bolting on anything to make the vehicle pass emissions requirements, removing emissions devices actually helped. These days? The PCM and the engine are designed to have those devices in place and operating correctly.
While I understand the impulse to gut the cat if it melts because you don't have the disposable income to do it right, I just don't think removing the cat these days is a smart idea.
Of course, if you want to stick it to the man, well, have fun, but realize it can come at a price
