2004 ram hemi question

[yakdick]

i thought i would ask here first before i joined another dodge forum. i just bought a 2500 4x4 5.7 hemi and will be installing shorty headers, deleteing the cats and putting 2.5 inch duals on it. can i just leave my rear o2 sensors hanging under the truck like i did on my srt-10? or do i need simulators or is there a programmer available that i can use to delete the rear 02s from the computer?

I had to have a tune to delete mine on my 06. otherwise i kept throwing a code. When i used the mechanical simulators it worked also...

Either get in tuned to delete or just have some bungs installed

why not LTs for the tq of a 2500 in stead of shorites?

I got the tune and deleted them.

With the headers and catless mids. Your going to need a tune anyway. I would just delete them. But thats just me.
