It did it from day one.
If you had the mufflers and air cleaner installed, then you would be required to add a fuel management system, or at a minimum, have a stage-I reflash performed, or else you're running lean.
Adding the injectors was due to another issue, and has nothing to do with your a/f mixture after modding the intake AND exhaust of t your bike.
If that was done, then you're either likely still lea, or have an exhaust leak somewhere.
Those are the two things that cause those popping. That's not to say you may not have n intake vacuum leak, but that falls under "lean" as well.
