Ok, what year and model?
You really can't mess with the sensor configuration. If you have just a single primary sensor, you will have to install an x-pipe and put the sensor in there. If you have a single downstream sensor, you are going to have to get a single exhaust that splits into two somewhere aft of the rear sensor.

You truck CAN run like *** and get horrible power and mileage if you "mess" with the O2 sensors. Cutting the wires is another terrible idea (are you serious??). They are there for a reason.
However, depending on the year/model (which you still have not mentioned) there may be a way around the problem.
Either help us help you or PLEASE take your truck to a decent muffler shop to do the work for you.

Yeah, the new generation motors are fairly reasonable to dual, but the carbed motors that were adapted for fuel injection are not set up in a way that is compatible with dual exhausts. By new generation motors, I mean the 4.2L, 4.6L and 5.4L. They were designed for fuel injection, and the OBD-II seteps for these engines are usual treated as seperate banks, with upstream and downstream sensors on each bank. The older motors are setup with a single upstream sensor and a sigle downstream sensor. A few might be setup with upstream sensors on each bank, but they still have only one dowstream. This makes a true dual exahust more difficult to set up.

what do the sensors do tho if i removed them wouldnt the check engine light just come on? i dont see how it could make my truck run ****ty, my buddy put duals on his truck and he just had an O2 senser so he just snipped it, the truck still runs fine.

Removing any sensor can make the PCM go into "limp mode" - since it doesnt know whats going on, it reverts back to a preprgrammed set of values for fuel, timing, etc. Most Fords will run very rich to keep from hurting the engine. That will hurt things in the long run. Washed cylinders, thinned oil, clogged cat, lots of things.

You buddy needs education, IMO. Please read up on what you are wanting to do, you will realise its NOT the smart way to go. You seem really bent on just cutting the sensors off and its an asinine way to work on a vehicle.

You will get a CEL and you will have drivability problems. And you will fail your safety inspection if you have any engine related or emission related codes, even if emissions testing is not required in your area.
If I were you, i'd just go with a dual out muffler and run them out behind each tire. I've had several people, both people on this forum and some of my local customers, tell me that this arrangement is louder than true duals.

(hotrod96, What part of AB are you in?) Dont cut anything, if there is no noticable difference, chances are the truck wasnt running right to begin with. And is your buddys truck the same year? Make? engine? Myself, im going with a single 3 inch system on my 96 302 (Ive always liked a single 3 inch over duals). No messing with sensors, plenty of flow, love the sound, and one less muffler to buy. I will be getting long tube headers, as well as high flow y pipe and cats.

Yeah, before you even consider cutting a wire you should price out a computer, at least make sure you know where to get another. Its really not worth messing up. I know some people do run duals and just run the O2 sensors on one side, but that creates problems with accurate readings and it take a while to warm up the sensor enough for it to start working. You will tend to run rich and waste fuel.

I live in northern alberta about 2 hours north west of edmonton. bout 15 mins away from a town called fort assiniboine, pretty much in the stix lol. my buddy's truck is an 88 Chev 1 ton with a 454, headers, and 2 1/2 tru duals complete with flowmaster super 40's. pretty sweet system. How many sensors are on the 96? i think the 94's and 95's had 2 sensors one in the back and front but i think that was changed in 96 wasnt it? if there is only one in the front ill just put an X pipe in and put the sensor in the middle.

mine is 2wd so there is lots of room. so i guess i only have to worry bout the one sensor since im not puttin headers on (yet). awsome thats good news, an X pipe should do the trick thanx alot guys.
