Question Oxygen Sensors?

I am replacing my entire exhaust system on my 2002 V-10 F-250 Super Duty.

I'm going with the Banks Torque Tubes headers and a Flowmaster cat back exhaust. They are on order and but I am waiting for a back order on the cat back.

The oxygen sensors are 12 years old and I don't want to reuse them. How many oxygen sensors are in the stock exhaust?

There are 2. One on each bank. I am not a fan of Flowmaster. Lots of drone and anything but flow.

Question Best Cat Back choice?

V10man,

Thanks for the information! The Flowmaster is out of stock, so what is a better choice?

Is the Banks Monster exhaust a better choice? What's best for a 2002 2 valve?

That depends on your vehicle. If it was built as an OBDII compliant truck (like mine ) , it has three O2 sensors . Two are before the cat ,one at each bank , and one after the cat . Check your emission sticker on radiator to see if you have an OBD I or an OBDII truck ,or , get underneath take a look .

2000 F-53 chassis w/ Winnebago Motor Homr built on it.
I was under my uniy last week and found the two sensors before the cat.....one in each exhaust header. BUT, I was unable to find a sensor after the Cat!!!!!!

Am I missing something or is this the norm???
Also, I may be having some cat issues so what would happen if I removed the cat and put in a straight pipe for test purposes??

Advise, please.
Looking at solving a "misfire" issue of 5 of the 10 cylinders and wonder if my cat is plugged.

That's normal for a "federal" emissions OBD1 system.

Which 5 cylinders are misfiring?

Here;s what came up on my code reader:
P0301(2); P0302(1); P0305(3); P0306(4); P0310(5).
This is a cylinder misfire (and I expect the #of events in parenthesis).

Advise, please.
Thanks for your time.

..................

Here is a link with good diagnostic information . Although it is for Ford 8 cyl. engine , it is mostly universal information . Your cylinder numbers ; starting from passenger side front 1 -thru 5 (5 is the back) , driver side front 6 thru 10 (10 is back) . This should put you in the right direction.
Good luck,

Follow-Up

Wasn't sure if I posted any follow-up on my multiple misfire problem, so Here it is.
Driving back from Florida in March, my Winnebago Motor Home w/ a Triton V-10 (2000 Built Ford Chassis) began to 'shudder', no power, all kinds of not-so-nice things to happen when driving a big brick on the highway.

Got home OK.
Began the investigation. 5 cylinders had multiple misfires.
Short story....after looking into many possibilities, the gas seemed to be the culprit.
So, had about 1/4 tank of gas. Decided to go for a "test" run.
Maximum stress on the unit. Hooked up the tow vehicle, filled the tank with 93 oct and went for a drive, up two of the steepest hill in my area of Pa.
Had the code reader hooked up to detect any misfires.

Result: Drove 50 miles, up two big hills (max stress on the V-10) and recorded NO misfires.
Tranny shifted perfectly, engine ran like new, lots of power, etc.

I suspect that my last fill-up at a Flying J in Va. was the source of my 'bad gas'.
So, now ready for my next trip to Fla. in a couple of months.

as long as the CAT is back in during your state regulated inspection.....in NYC...its and auto fail if the exhaust system as been tampered with (by passing cats).
