Congrats on the addition.

I definitely heard a difference with them installed.
Not sure if you are aware, and this may not be applicable to you, but check to see if you have a low frequency cut applied to your audio system. There was a decent base increase with the ports installed, but once I got them to reprogram the amp with the correct frequency profile, the increase was substantial.
There are other threads in here that discuss this issue and you may not be able to change the frequency profile if you have the older amp installed. I really should have taken better note of what bike you have this on. I forget the #s too, but something like the standard profile cuts at 80Hz and I'm assuming that the new profile cuts at 60Hz, although I don't have any idea what the actual #s are.
Again, congratulations and enjoy the ride!
