Good afternoon everyone,

I own a 2002 Electra Glide Ultra Classic. I have been having issue past few months with the bike sputtering under 3k rpm and when I down shift it has been popping and back firing more often. I did not think about it till today but all this started a few weeks after I removed the Y pipe and replaced it with the pipes needed to convert it into a true dual exhaust. When you turn the exhaust into a true dual does the bike need to be tuned?

 

Yep, sounds like you should tune it.

 

Sounds like you know what to do.

 

Tuning it will probably show an exhaust leak so yes, start with a tune.

 

I would also check the fuel system starting with the fuel filter.
