^ Well here's the thing. The stock exhaust note is considered super quiet compared to the 350Z. There's no doubt that I like the sound of the F.I. exhaust, but the drone around 2-3k RPM is my biggest issue as a daily driver. It is loud enough to drown out music and phone conversations (handsfree). Outside of this range, the sound is phenomenal and nowhere near as loud even at 7,500 RPM.
In an effort to reduce the dB in the 2-3k RPM range, I will switch to the stock cats. Hopefully that's enough.
