I'm considering the Thundermax with the Auto Tune module. I'm going to be installing this on an 06 Ultra. My question is do I need to change out my stock head pipes to accommodate the O2 sensors. Also where would be the best place to purchase, by best I mean service and support as well as price.

Thanks

 

Your stock head pipes will work just fine.

 

Being an '06, I dont believe he has the O2 bungs.

Here is a cheap fix to use your stock headers. Just have a metal shop weld them in. I think it has to be within three inches of the manifold.
