95 F150 Xlt 5.0 efi 2wd
When I first got my 95 f150 it had duels the previous owner said some one cut off both cats and added duels ,a mechanic told me he could figure out why the check light was periodically come on and go off and when I told him this he said no wonder then he showed me this can and a hose on one end the hoes supposed to connect to exhaust cat it's called a charcoal can he said toch it and the engine light came on when I let go it went out so I was satisfied .

I hate to revive a very old thread but I'm curious to know if this will work with the OBD-I system on a 95 F150 5.0 with a single O2 sensor located before the first cat where the exhaust pipe from the two exhaust manifolds come together. Many of the simulators I've seen seem to be designed for the two-O2 sensor setups on the 96 and newer vehicles with the OBD-II system.

No cats?

Just one question.. how was your gas mileage? My husband has a 99 f150 4.6 manual and I have an 04 4.6 auto.. technically he should get better gas mileage being a manual, but due to a custom exhaust someone had installed and removed the cats, sure sounds nice, has good get up and go but his gas mileage sucks *** and mine blows the doors off his milage.. I'm trying to keep my cats and am replacing my 02 sensors which are probably the original ones, came across this researching easier removal because they are so rusted on that it's definitely not going to be easy! I told my husband after he told me about his exhaust that I thought that was why his gas mileage sucks ***!
Purpose of the 2 after the cats is to make sure the cats are working properly and burning off any unburned fuel and other gases that would normally go into atmosphere.

also you need to verify/ compare rolling diameter of the wheel/tire combos, OD gear and differential to begin making comparisons of mpg. Just because the manual may be slightly more efficient it won’t overcome improper shift points either… just throwing out things to consider
