Glad you went with the HKS AK. I love mine and I am sure you will love yours. The note will change a bit after about 2-3k miles, a little more low end rummble and tons more of that pop, pop, pop sound when you barely touch the peddle on idle. When I almost hit red line and shift this thing sounds like some kind of high end exotic car pure amazing, made me fall in love with the VQ37 all over agian. I love it. To bad I need to sell it to someone that wants to pick it up in Texas becuase I am going turbo. I might do a custom HKS turbo exhaust though
HKS FTW, oh and I love that d@m go pro you got, I got to get one for sure.
