I have dynatech LT's and have the catted y-pipe, and i am thinking about getting the of road y-pipe just until i have to smog which will be in a couple years. Will my O2's go into the off road pipe, or do i just eliminate them, and how do i do that?

 

the ORY will only utilize the front o2's, which your existing ones will fit. the rear o2's aren't installed. you'll need to turn them off in the tune or add simulators to compensate in the computer

 

what do people reccomend? getting simulators or just turning them off?

 

It all depends if you plan on getting a tune done soon. Getting a tune, get the rear O2 sensors removed. If not just get the O2 sensors simulators so you can reinstall the cats,etc for smog. My vote goes for getting the simulators but thats just me.

 

i have HPT, but i actually don't know how to turn them off, i guess i'll post on HPT site. But yah, i want to keep the front ones, and just run the off roady pipe and tune the truck for that. If anyone knows how to eliminate them on HPT let me know.
