Yes I like this sound.

I would def use both killers and get her mapped, preferably on a dyno and I think you will find the sound changes again. Also a bit more back pressure helps the tuner. And hunt less in my experience.

Hi Ricky I have this setup on my 21 XR I also have a BT MOTO tune which eliminates the cold start. Worth doing in my opinion
