I am purchasing a set of coated hedman longtubes 68460 and am just wondering where to put the o2 sensor. should I weld it into the collecters? i saw a 3 flange reducer pair in jegs with built in o2 fitting-anyone have/recommend that? thanks

 

I ran into the problem with Hedman Hedders also with the O2 bung not there. If you are going to buy them from Jet Hot ask them to do the O2 bung. I had to send mine back to them to take care of this problem. It seems that the batch that they recieved from Hedman did not have them already on the header. At least that was what Jet Hots Tech support people said.
