well good luck either way, and you might want to have bill write a tune before you remove the 2nd set or the truck might not run right... just a thought...

If they're that badly rusted in...... bite the bullet and buy NEW ones......anytime you do exhaust work be prepared for extra cost.......ticopowell is also correct that Bill can turn off the rear ones but you still need the fronts!
O2 sensor do have a scheduled change out interval based on mileage.....

I finally got the 2 front ones out and put them back on. I left the 2 back ones off though since I couldn't get them out even after letting them have PB Blaster soak in over the course of a week. Ended up just plugging the holes for those on my new resonators. Seems to be running just fine though.

I still think you need a tune in order for your truck to perform properly. I don't know what would go wrong, but there could be quite a bit that is affected by not having the rear o2's when the computer thinks that they are there. is the truck throwing any codes?
