What are some good recomendations on cat. converters?

I'm thinking my is getting clogged, and I want a nice one to replace my stock one. I have an 03 model year with the NGC so it would have to work with both 02 sensors and not throw any codes. What is the average price range I should be looking at, and what are some good ones out on the market that I can use? Thanks for any help.

I have a Magnaflow cat. Cost about $130 or so. Seems to do the job quite nicely

I might consider one. Do you have a spot to put the downstream o2 sensor? I know our downstreams are in the middle of the cat., so how would the readings be affected?

I could also gut it, but I'm sure that would trip my sensor, unless I could do the spark-plug non-fouler mod.

I'm thinking I might get the one with a bung in place, and a thermal muffler. This a good one?

This might restore some lost power I have.

If you get one just make sure you get one that already has an bung for the 02 sensor. Those look alot shorter than the one I have. The one I bought connected directly to the stock exhuast and manifold. The o2 censor plugged right in.

Is there a certain milegae that the cat seems to clog up, or does it just happen to every car at a different time??

I'm having a hard time finding a place that will cut out my cat and replace it. They all say that by law they are not allowed to mess with cat.s unless the car is 8 years old, or has 80K miles on it. They say I should go to the dealer and get it replaced for free since there is a federal law on all cat. converters.
