I have finally got everything installed.
Ok, love the Gibson. It IS noticable, not in a bad way, has the highest tone at 1500 - 2000 rpms.
Took bunch of pics during install hope they are good. The only problem with install was a gasket, at the Y. Speeking of the Y, the stock sucks, some pics will show this.
The Gibson and the Injen together is a great comb. At full throttle it's a roar like no other. I believe the dyno numbers from Injen in the 2.5K - 3.5 which is most likely 28hp/43tq, and peak at ~17.
I will try to get the track to see the results, nothing to compare to other than my 04 Maxima with Injen. It's hard to compare track times from diff locations, temps, ... the track in Indy seems to get slow times for everybody.
I will also try to get sound clips, it will take a while since I am not at home with her (Serena - Armada) during the week.
