Noooooo you got it before me!!!! I was gonna get it last week but things came up. We both have PW Z's in San Jose. Maybe one day I can listen to it. Did you get HFCs as well?

Hey man, you'll definitely love it. For the price, you can't go wrong. Let me know if you want to check it out sometime. I'm right by the SJ airport :-). Good luck. Also, you should talk to the guys at Speed Element if you decide to get it. They treated me very well.

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.

HFC are back in stock PM me for a killer price.

ERZ HFC are re branded under CNT Racing

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

:tiphat:

Invidia is also a great choice I sell them also.

question... not to thread jack or anything, but has anyone dyno'd HFC's vs. test pipes?

from what I have seen and heard, It was a diff of under 5 WHP for TP's over HFC. OP great write up and work.

you guys using these hfc's..are u using an extra extension on the 02 sensor or is the built in extension fine.

I just ordered & installed the CNT hfc from nissangen's groupbuy. There are built in 02 extenders and I have not received a code(only had it on for like 2 days). It definitely makes the exhaust sound a lot deeper and louder, and hiss is VERY minimal. There is sometimes an exhaust burble sound, some people like it, some people dislike it.
