Possible Front 02s Shot?! **UPDATE**
P1133 Code! 
Allen seems to think my 02s are going bad. Should I replace both or just the bad one? Should I stall Gm stock or is there a good after market one? What do I need to look for?

I had to replace 2 when I put my LT's on. I found out that 03-05 all called for the same part number through GM. When I bought one aftermarket through auto zone (Bosch), opened the box and it was the same sensor as what GM gave me. The numbers on the side of the sensor it self were exaclty the same.
There is a good chance no matter where you guy your sensor, it will be the same part, so go for the cheapest buy!

Why did you have to replace yours? I have a SES light from what I think is caused from the rears even though they are tuned out. Maybe it's not from the rears. Runs fine though.

I don't recall the part number off the top of my head. Yet it was the same part number for all 4 sensors dating back to 03. I'm willing to bet you'd have the same scenario.
I had to replace 2 of mine when I took the rear 2 sensors off the stock Y pipe, stripped a few threads during the process.

Since you say "not yet" on the LT headers I'd assume you will get them one day...if so you will more than likely get this (and other) codes again. I'd say get the corvette rear o2's instead. Their heaters are a little hotter and may(not always) help matters when you do end up with long tubes. Bosch 13111 is the rear vette o2's.
