I would also like a little input on this. When I start my car, the exhaust is cool. Once its warmed up, they are a little warm but no where near hot. I can hold my hand there for as long as I want.
I'm not sure how hot they should be so I don't know if that is normal. My car feels bogged down below 3-3.5k rpms. Once I hit 4k though, it feels nice and smooth. I'm thinking I might have a dead cat.

whats weird i have this problem and i thought my cat was dead too. get a backpressure test done. mine was almost near pefect, but might be a bad in your case. i live in CA where i have 2 cats and im thinking about replacing my warm up cat but dont wana waste money. hah
