The stock exhaust was just to quiet for the type of car this is. The Z needed more of a roar. I didn't want something that was just stupid loud as I DD my car. The Invidia Gemini was the perfect exhaust to get. Under normal driving and idle it almost sounds stock. When you give some throttle sounds nice and clean.
So heres a video of my stock exhaust (for comparison)

And here is the video of the Invidia Gemini CBE with resonator delete. They were pretty mild revs.
