Exhaust

The Fast Intentions catback with stock cats were ricer loud with massive 100db+ (measured) drone inside the car. That will literally make you deaf over time. The drone was headache-inducing.

The HKS, in contrast, uses Helmholtz resonators to remove all sound at the frequency that resonates in the 370Z cabin, for a drone-free experience. When you're idling along it sounds little louder than stock, but put your foot halfway or more into it and it wakes up with an aggressive growl that still is never annoyingly loud. It's what a sports car should sound like, IMO. It's more expensive but oh so worth it.

I had a shop procure and install them so I'm not sure of the model number. They said it was the only HKS for the 370Z that's imported to the USA< so not sure if that helps. It also supposedly only comes with the blue titanium tips so with that and the extra Helmholtz canisters you can see in pics nears the end of the exhaust (see below) you should be able to get the right ones.

I have the F.I. setup with stock cats and the last thing that comes to mind is ricer loud. The car drones slightly when the engine gets put under load, like stepping on the gas in 6th at 60mph. Other than that, the car doesn't drone at all and sounds like sex.
