Well, looking at getting a header to replace the old stock one. what stuff do I wanna look for like specs and what not. I know it should be like a 4-2-1, 2 piece is easy to install i heard, Im not installing it anyways. What are they suppose to come with? What is the 02 sensor, i've been seeing that around here and there.

Thanks.

I wouldn't get a 2-piece if I had the chance again. I recently had an exhaust leak in the 2-piece joint and it was a pain to have to fix. I put the 2 pieces together and then installed it - I really couldn't figure out what would be easier about having 2 pieces. It actually seemed like it'd be harder, because there's little room to tighten those joint bolts down.

^ i did the same thing when i installed my 2-piece, just assembled it beforehand and installed it as one piece. I agree theres not much room to tighten those bolts, so getting a 1-piece would eliminate any possibly leaks, and be just as easy to install as the 2-piece.
