Are my Cats going out?
I've replaced every ignition component, plugs wires, headers, gasket, and you can see the stuff I've done to the car in my sig.
When I first start the car up, it runs great, but after five minutes, it's like I loose 75% of the power. I'm also getting extreme heat from my cats, and there's this funny sweet kinda burning smell. The cats have about 139,000 miles on them, and I'm sure they could be going out, but I wanted to hear some other testimoniasl. Help me on this one guys!!! please?

Get under your car and bang on the cats. If the insides are rattling like hell, its time for some new cats
