After seeing bluestyle55's review
Invidia Gemini CBE & ERZ HFC Review (with db comparison) of the Invidia Gemini and ERZ HFC I decided this was the exhaust for me. I am pleased to report the quality of this exhaust is just as great as the pictures portray. I got a stellar deal from ECS Motor Sports for the Invidia Gemini with the new Stainless Steal tips. I still can not believe I got a full cat back exhaust of this build quality for a price under $900.00! And the exhaust sounds just as good as it looks. I previously had the ERZ HFC installed with the stock exhaust which sounded pretty good just a bit raspy for my liking. After adding the Invidia Gemini my Z now has a deep growl to it. For those on the fence about this exhaust being too loud I can tell you it is definitely not too loud. When you’re just cruising under very light throttle it is pretty tame but when you get into the throttle from 2500 - 4500 rpm it really screams best of both worlds. I included some pics of the exhaust on my car and plan on taking it to the Drag strip to see how she does. With the new exhaust installed I should be able to break into the 12's. I will post another tread after I have a chance to run it at San Antonio Raceway.
