Took all of 1hr 20min to remove the stock and install the full system. Is nice and easy when its all new still.
Its not overly loud, which is good. But to be honest, i expected more. Even with the dB killer out, I thought it would be louder.
But when you open it up and get the revs up, its starts to produce some nice chords

I can notice the power increase for sure. Mainly due to the wheelies while roll ons in 2nd. Doesnt need to be clutched up, or bounced up. Just roll it on, and keep going.
Also found the delivery is smoother. Smoother gear changes, smoother rpm up and down. And a rather bothering vibration around the 9k rpm area is gone.
I weighed the stock system on the scales at work, compared to the full Akra. I forget the figures

Still waiting for the Power Commander 5 to be release for the Z so I can install it and the apropriate map.



Enjoy
