Awesome exhaust AK and I'm not just saying that cuz I have it too
. I'll be doing a post about it soon as it's long overdue but I will share a few things here. I also like how it has a nice tone but is not overbearing. It makes me think it will still sound reasonable with cats on it later. I think some people don't consider that when they listen to sound clips of the cat back alone then put cats on to find it's annoying.
In terms of power I'm going to say it's on par with the others. My car gained a few HP over the true dual that comes on the Nismo stock, making just over 300 to the wheels peak. It would make a more dramatic difference over the regular exhaust on the Z.

It doesn't come with silencers, the bolts you see on the side is to adjust the tip in or out more.

Those extra canisters are tuned resonators. The are there to reduce the amount of rasp inherent on the VQ engine somewhere between 3k-5k rpm. Just recently HKS changed the muffler section to fine tune those also.
As far as tips for Nismo owners (which I will expand on in my post) There is another tip they use on the G37 version that is longer that if you really want you can buy seperate (since the Nismo bumper comes out more). It's not really necessary and is a matter of taste, up to you. Also on the drivers side rear section (muffler section) there is an additional hanger bracket that must be removed to avoid the exhaust from hanging crooked. HKS had made supplement instructions now for Nismo onwers
. I don't want to seem like im thread jacking though so I'll save it for later. Again sweet exhaust AK!
