Catalytic converter advice??
I need a new cat but the OEM stock converter costs a fortune. Anyone have any suggestions on what would be a good aftermarket cat to buy thats not too pricey?

The cobb access port is something you would have to buy. You may be able to find a used one in the for sale section. If not you could pick up a new one for about $500 without the tuning service or $600 with tuning. You may be able to find a used cat on the forums for ~$400. The oem cat is a decent one, most brands wont last at all and you will burn right through them.
How badly is your cat clogged up? If you are still driving and it is causing excessive back pressure you could be doing damage to your engine. You might want to consider doing a compression check on it at the dealer. However if you are worried about the cost of a cat then an engine probably is not on the horizon.
When was the last time you replaced your spark plugs, coils, and wires?

Don't forget Cobb though, it is a great tool that you can program to increase oil use for lubrication, program to ignore certain cel codes, increase idle, and increase/decrease redline, and change timing. I don't suggest messing with rpm limit. But it's a great item. How do you know you need a cat?

well i took it in when i got it because the CEL came on when i was driving it home from the dealer which is two hours away from where i live. the code came up saying it was the cat but idt its too clogged or even clogged at all. The car hasnt progressively run bad or anything. seems to run the same as it did the first few days that i had it. havent really had a chance to take it back in to get it looked at but its running okay. if you go behind the car and listen to the exhaust you will hear a thump kind of sound here and there but its not constantly doing it. could just be the spark plugs but the wires and coils look almost new. they dont look original to me. idk how the last owner treated it either which is why i posted the engine decarb thread as well so i can clean it up and remove any buildup that could be in there. ive had it since december and havent had any problems with it running bad so its probably something minor.

Would it be better just to punch out the cat instead or will it hurt the engine? it doesnt seem to have a loss of compression either because the rpm look normal when its idling but i could be wrong. My biggest problem is having the money to replace all of that if its even necessary to replace. theres no point in replacing something if theres nothin wrong with it so ill just get the compression checked along with the plugs and coils. as for the cat i might just have to ask for an early Christmas present... lol JK

depending on the dealer compression checks can run from $100-$150.
keep the cat, even if it might be a little clogged...it will have some value still that way. just get a midpipe, you can find used AP midpipes on here for very cheap (as little as $100) and are very commonly used.

when i have the AC on it just makes the car vibrate at idle. with it off it wont vibrate. you can only BARELY hear the rough idle through the exhaust. its not very rough but i wouldnt consider it to be normal you know?
