Moving O2's
 

This might be a stupid question but I was wondering if moving my O2's from my headers back about 6inches to my x-pipe would cause any problems. I have tried everything I could to get the old ones out but the headers are pretty rusty and the plugs dont budge. I planned on just drilling holes and welding new bungs on. Which brings me to my second question, can I just pick one up at a hardware store or is it something I have to order?

Thanks

im assuming you have lt's. the sensors are already quite far back. moving them further will cause issues with your ecm. try getting the exhaust hot, and use a small pipe wrench on the o2's... they will come out if you put some muscle behind them.
