Guys,

I did some searching and can't seem to find any good recommendations for shorty headers and off road 2 into 1 pipe.

The truck is a 5.0, Supercab, 2wd. I owned a truck like this years ago and intended to do these exact mods. I researched and found all of the part numbers, almost bought the parts, but ended up going to a diesel truck since kids came along and I needed a crew cab and a big tow vehicle.

I have since bought another truck like this for my son and the previous owner cut the cats off (said they were clogged) and did a horrible job of replacing the cats with some extremely small pipe which I feel is choking the engine and left the O2 sensors plugs hanging...

I'm looking for stock replacement 1-5/8" tube shorty headers and a factory replacement 2.5" to 3" off road pipe. Also, need the things you plug in place of the O2 sensors to make the computer think there still installed.

I plan make the rest of the side exit exhaust in my shop...

 

Found this picture on Rockauto.com. It looks like they sell full kits for your truck.

 

Found this on Jeg's. Will round it out with a custom 3" system from the Y connector back.

Should only be one O2 sensor unless it is a MAF truck, but in either case these sensors cannot be eliminated as they are the only feedback the computer has on fueling.
