These are the 1 3/4" coated headers w/ AIR 1cat. I was woundering if these came with two o'2 bungs, and if they cam with their own y-pipe. I need two provisions for both oxygen sensors of the LT1. If they do not then I will just get the non coated, add the bung, and then have them coated. I just don't want to add the bung and destroy/discolor the coating. Thanks.

 

I bought the ceramic coated 1 3/4 inch headers without the AIR inlets. I only had 1 fitting for an 02 censor on the driver's side header.

Your best bet is to give them a call and check it out to make sure.

Single bung on the driver side. Get uncoated ones and weld what you want where you want and then you can coat them

 

So do they come with their own y-pipe? Any one have any pictures? I guess I will go with the 3001, the non-coated ones. Any one know roughly how much it would be to have them coated? Who should I have coat them?

 

they should come with a Y Pipe but you are also going to need a few more things. You need their gasket set and a small elbow for between your Y pipe and your cat(s). I think both of those are about an extra 40 - 50 bucks.

Could I just get the coated one and then add the additional O2 sensor in the y-pipe on the passenger side?

 

It depends on how fussy you are. You could get the coated ones, drill a hole and weld a bung there. It probably has to be welded so it might scar up the finish a little but that is an alternative.
