I was wondering if the DNA slip ons would fit the head pipe on a 2017, 107 to 114 stage 3 conversion. i know stock head pipe and heat shields are different. some of the pics ive seen of the DNA's show one side has bigger diameter where muffler meets head pipe and crossover. Let me know what you guys heard or what you know please.

Thanks,
RD

 

I am not sure if they will fit. My experience with DNA mufflers that they were way too loud. I had them on a 103 motor and hated them. This is my opinion,

 

If you have the Screamin Eagle high flow head pipe, the only slip ons that will work are the high flow Screamin Eagle mufflers. The stock head pipe has a catalytic converter in the head pipe with open mufflers. Once you go to the Screamin Eagle high flow exhaust, the catalytic converters get moved to the mufflers with an open head pipe, and the diameter of the muffler inlets change. They do this to stay within EPA regulations and good graces, and also to ensure that you only purchase the Harley branded mufflers, because they're the only ones that will fit that head pipe. They don't want you putting on a head pipe that has no cat and then putting on another brands mufflers, that also have no converter.

 

i hated mine as well
