Catalytic Converter

Catalytic Converter
One of my friend helped me out check why I had a engine light came on again after replacing O2 sensor and the result was I needed a Catalytic Converter replacement.
I have a couple questions tho..
I was quoted with $390 for a replacement but how long can I drive with a broken converter? I was told it just a federal law for to pass emission inspection sticker and I'm still driving with a rejection sticker for almost a month!
I wanted to get a Magnaflow goes for about $65-125 avg compare to OEM $390 one...
So what would be the best ideal for me?
Thanks!
In a year or so I might have to consider getting a new car I've been getting allot problems in less 5 months. I will most def get Maxima again!

I suppose I can attest to what a clogged cat can do; I was getting off a highway exit when I noticed a lack of power. Managed to limp it to a friends house and had to get it towed from there. No blown motor, but I'm sure if I tried to push it it would've been bad news. Either way, gut that **** and get an o2 sensor if your inspection laws "allow" for it (i.e. no exhaust sniffing in your state, just straight up code reading).

I'm pretty much a newbie about exhaust systems... what do you mean gut my pre-cat do you mean cutting it or replace it?

pre cat
5th gen Maxima with VQ35DE engine:
: two precat : one near the radiator, Secondary Oxygen Sensor with red wire , one near the firewall , Secondary Oxygen Sensor with white wire.
: Main rear catalytic converter
: Two Primary Oxygen Sensor with blue wire: both near the exhaust manifold
Solution: gut the precat means, removal of mesh inside the precat and install it back, or remove the precat and install a header (OBX headers)
: Install a non-fouler to the two Secondary 02 sensor or O2 Sim
: Retain the main catalytic converter.

gutting = removing the insides of the cat so it looks functional from the outside but is just a shell. You will need an o2 simulator or o2 nonfoulers to trick the ecu into thinking that it is fully functional. It's illegal to do so you will need to find a friend who is a friend who is a mechanic to do the work. It's cheaper than replacing the precats and you will get more power this way.

Would you still get a code if you gut the precat? Also, what does it mean when you've had catalytic converter code and it goes away? I bought a catalytic converter for $170 and it's just sitting in my room for no reason now because the code came off. (If anyone would like to buy it ill sell it for $120 and that's negotiable. It's still in the box and all)

They are slightly different...both gens use similar exhaust setups, but the 2k2 and 2k3 seem to have more of an issue with the cats breaking apart on the inside and potentially causing damage to the engine. I haven't seen or heard of this on 2k and 2k1 Maximas.

Due to all the rust. It looks like it would be a PITA to remove and gut it. I figure I would just replace mine with a brand new aftermarket one. Maybe Eastern brand and replace the 02 sensor. From the look of mine, it looks like they will damn near half to destroy it just to remove it.

I think that Warpspeed makes an entire y pipe and hi flow cat set up for this gen. I would just swap it all out with new. I've never done an exhaust job where I didn't need heat, or I didn't need to cut something. I'm in Philly though, where salt and snow are a factor...

The Warpspeed Y-pipe reliminates bank 1 precat for only the 2000 and 2001 maxima. You still will have the Bank 2 precat which I think is odd since it throws off the balance of the flow, but that's just my opinion.
