Clogged Cat???

Clogged Cat???
Just recently, whenever I start my car after it has been sitting for a long time (8+ hours), it idles a little rough. When I start accelerating, it has a small stuttering problem from first to second and not so much from second to third and so on. I have an A4 BTW. After about 3-4 minutes of driving, this symptom disappears and I have no problems until the car has been sitting for a long time. It almost seems to me as if this problem lasts long enough for the AIR pump to heat up the cat. Anyone experience the same problem? And was it the cat fixing to take a dump? TIA

i think my cat may be cloged after 174000 miles, i think i may just "punch" it out. Can this be done with the y-pipe still on the car? What should i use, i have a 1 1/2' screwdriver that might work.

would the exhaust blow all of the crap out? Im afraid that some sht might get stuck in the y-pipe and makee things worse. What is actually in a cat? Its like mesh of some metal, can't remember which one tho.
