Great review and vids. Reps for you. Does anyone know if the F.I HFC specifically the resonated one will fit this invidia CBE? I want the power from the hfc but without the added cabin noise and hoping the resonated hfc from FI combined with design of this invidia can give me that.

I know in you vid the ERZ cats only gave a slight db increase but there were points where the humm Noise sound like it could get annoying.

bluestyle55 thanks for the great video, Those Subaru guys give me 10 second videos with video camera right on the tip (I was like that took a lot of time)

You will no be unhappy with the Gemini... 950$, polished stainless steel, titanium tips, eliminates the Hiss of a HFC....CAN'T GO WRONG!! :happydance:
Track Update from last nights runs:
The ERZ HFC’s definitely improved my 370z performance check out my trap speeds! Best time for the night was 13.165 2.03 60'ft @ 108.85 mph. The fastest trap speed and time was 13.23 2.18 60'ft @ 109.49mph. Need to work on my launch. But I am only about 1mph away from the best time I have seen on this forum 12.80 @ 110.33mph with Stillen G3, CBE, and HFC. I maybe able to trap 111mph with the Invidia Gemini and I should already be in the high 12’s just need some practice!:tup:

I'll have some vids in early April of my car on the track. Figure that should make for some nice sound clips :).

resonated test pipe are in stock now

AH370Z 03-13-2010 02:34 PM
Any plans for resonated HFC like F.I. Would they reduce the noise the hfc add

ERZperformance 03-13-2010 03:53 PM
Sorry we don't have any plans as of now making those.

puckshaw 03-15-2010 04:51 PM
Awesome video! That combo sounds sick! It's hard not to seriously consider the Invidia at that price point. Decisions, decisions...
