Magnaflow catalytic converter part #23706 oxygen sensor port too small
#1
NOS 2010-prod Magnaflow catalytic converter part #23706 oxygen sensor port too small
*** EDIT: only old-stock Magnaflow converters of this part number have my issue. They fixed it in November 2014, so a post-11/2014-production unit will have the correct sized oxygen sensor bung. Mine was made in December 2010
************************************************
for the 95-96 Maxima/I30 with the oxygen sensor in the main cat.
Therefore, you cannot screw the o2 sensor into the bung provided in the cat.
Other than that, the flanges were done correctly, and the Magnaflow converter looks like a high quality part. Just too bad you cannot screw in the oxygen sensor since the bung is too small.
The Magnaflow convertercame with two OEM Nissan gaskets included.
I tested it with a brand new NTK oxygen sensor part #24024, the actual OE part.
Can an exhaust shop weld in the hole from the old cat? Swap the old cat's oxygen sensor hole into the new one?
The California-legal CARB-approved equivalent converter part number is 441704

Its not the wrong O2 bung, its just smaller. The emissions sensor that plugs into 95-96 isnt the "standard" size, but you can get the correct, smaller size off rockauto or somewhere similar.
sorry i dont have more info on hand like what the size is but its the dame thing just a lot thinner.

If there any chance you received part number 24630 in a 24024 box?
Here's a picture of the 24024 sensor with the small tip for a 95-96 model.

Here's a picture of the larger tip 24630 for later models.

@CS, yes, I am aware of the difference between the 95-96 and 97+ sensors. The one I have looks like your first picture, the smaller tip, with the brown 3-wire connector.
@slamrod, I know it's not the standard size, but the hole is *still* too small.

I'm just spitballing here, but can you have it drilled out and rethreaded with a tap and die or heli coil? Something along those lines.

Yeah thats definitely a screwup. No way it should be that small, id look into seeing if you can get some sort of compensation for that. Unless theres some other purpose im not aware of, but certainly no O2 sensor that small is used on our cars.
Like said above, you can just drill it out to the correct size and retap it to the proper threading, this is probably the easiest and cheapest route to take and its something you can do yourself. Alternatively you could cut out that bung and weld in a new one but in all likelyhood its easier just to seal that one and weld in a new one next to it. Id go with just drilling and retapping, its straightforward as it is going to get.

Where did you get your converter? Can you return it and replace it with a different one?
I got my Magnaflow converter from WarpSpeed Performance and my NGK O2 Sensor # 24024 from RockAuto and everything fit perfectly.
Before getting the converter from WarpSpeed I bought a universal one from my neighborhood O'Reilly's only to later realize the difference in O2 sensor sizes. O'Reilly's happily accepted the return.

I bought mine on Amazon, thru the Amazon Warehouse Deals. It was only $69. I can probably return it, since they do give you at least 30 days to do so.

********** UPDATE ************
I got a response from Magnaflow!
My converter was 2010-production, and that they had fixed the issue in November 2014
So one made after 11/14 will have the correct size oxygen sensor hole
I am returning this old one now.
