Hey guys just a quick question on my 06 road king. if I were to just install screaming eagle slip on mufflers would I still need to have my bike mapped

Thanks

 

No.

 

You wouldn't need to. It might run better if you ahd it done, but no need. It would also help to get a different air fileter, one that flows better, but you don't need taht either. Maybe one thing at a time for you...
