Invidia Gemini CBE & ERZ HFC Review (with db comparison)

KusoSama · 09-09-2010, 12:06 PM

I've had this installed for 1000 miles now (roughly) and I can say that the noise from the exhaust has calmed significantly but the low-end responsiveness has stayed if not increased over time.

At cruising speeds you barely notice the exhaust has been changed from within the cabin.

At throttle, even slight throttle input, you'll hear the car become more "lively" through the exhaust. I'd comment on WOT but I usually don't stay in gear long enough to listen to this all too often. I know that it does get authoratative in sound at WOT but I don't feel it's obnoxious by any stretch.

On deceleration, near end of decel, there is a slight deep flutter sound it'll make. Kinda reminds me of the turbo flutter sound you get after installing a more open exhaust.

I'm still waiting on my dyno charts to post. They were done with a Mustang Dyno so the numbers are more realistic than a Dynojet.

I've recently been thinking about adding HFC's to my Invidia Gemini exhaust. I wonder if the Invidia HFC is a better choice.
