I am considering installing a PC-V w/ autotune on my 2012 wide glide w/ the thunderheader exhaust installed. Fuelmoto has told me that they dont know if the Thunderheaders have "dual 02 bungs" or not. The sensors with the PC-V require 18mm. Sorry, I havent been able to find any information elsewhere. Thanks for any response.

 

If you go to the thunderheader website they make a set for 2012 and up now. I think the part number is 1035b for black. Not sure if it has both size bungs or just the newer 12mm though. Check the classifieds there was a member that had a set for sale, maybe if you pm him he could answer better.

 

I already have the thunderheader installed, which is why I'm asking. I can't find any contact info to ask thunderheader directly. They seem to only provide phone numbers for other dealers..

 

If the pipes are already installed, just take a tape and measure the O2's.
12mm is just under 1/2".
18mm is close to 3/4".
You can't go wrong with that info.
Any old way the A/T kit comes with 18mm bungs ready to be welded on if necessary. Some pipes are made completely without bungs.

 

Well what they told me is that some aftermarket exhaust systems have dual 02 bungs. I know my stock sensors are 12mm but I'm not sure about the bungs. I'm just trying to figure out whether I'd need to drill and weld before I actually do it. Thanks.
