Thanks for all the help guys. I went under the truck and unplugged the front o2's and problem solved. Just as long as the truck doesn't try to lean itself out too much. I have to get some pipe ran after the headers, neighbors probably don't like it.

I sold the OBX Headers with the rubbing problem, and I have a set of pacesetters now. They don't rub, but they are really close to it.

Im going to put some pacesetters on my SS in about 2 weeks. Should i have my PCM programmed before or after I put the headers on? I plan on reprogramming anyways.

Can't run a computer programmed for headers and not run with headers. The tuner leans out the engine to compensate for the headers. Without the headers actually on there, you'll burn up your engine. Do the headers, then get it tuned.

The difference in fueling isnt that great that youll burn it up.

I was just going by what allen @ nelson performance said. I didn't think it would be that big a difference, but he seemed to think so.

Guess it all depends on the setup.
