I bought a set of pacesetter lt headers and the offroad y pipe to go with it. I haven't recieved it yet, so I was wanting to find out some info on the y pipe from people that already have it. I know that the headers have a spot for the front oxygen sensors, but does the y pipe have places for the rear oxygen sensors to screw into? I was just curious, because I had orignally planned on running the sensor simulators but i found out that they no longer sell them.

 

If you run the simulators you dont need to worry about the rear 02's, the simulators just plug into the pigtail for the 02 sensor. 02 not needed.

 

I believe there is a place for the rear o2's, but you might as well get a custom tune and have them disabled. They serve no purpose without cats and you will probaly get a dtc about the cats not functioning properly since they are not there anymore without a tune.

 

I plan on getting a tune in the near future, but I want to install the headers and I can't get the simulators anymore because the company that made them is now being sued for it.

 

You may see a dtc about the cats until you get the tune, but it won't hurt anything to drive that way.

 

What is a dtc? I'm new to the nbs trucks, so I'm not sure what that means.

 

check engine light will be on.

 

DTC = Diagnostic Trouble Code

 

There are spots to plug all of the O2 sensors in. My rear O2's are tuned out but I plugged them in anyway...

 

uhhhh my pipe didnt have spots for rear 02's...thats the point to a ORY no cats no rear o2's
