the G3's and HFC's would be a very nice start to upgrading the Z !!

there are vids of just the HFC's on, i like it...check youtube out

What?? Get with the program, man! ;)

YouTube - Project 370Z Dyno Test: Berk Technology High Flow Cats

This is the latest. The clip begins with the Berk HFCs w/ stock exhaust. Then the second part is the Berk HFCs with the prototype of the upcoming Berk CBE. And yes, Spearfish, you may feel free to rep me for finding these for you. ;)

Uh if you aren't sure about the exaust it seems like the G3 intake is the way to go. They are all around the same HP gain for each of the three mods with the G3 and HFC being about the same cost wise. Also if you get the G3 before you do the exhast you'll be able to hear the G3 breathing - its tough to hear once the exhaust is done :)

I'll rep you just because you're the mighty Semtex and found the videos for me. I was at work where they block YouTube and too lazy to wait for my iPhone to search for the vids :tiphat:

That Berk prototype CBE sounds SICK. It's settled then. Berk HFC first, Stillen G3 intake shortly after, Berk CBE whenever if it shows good gains.

Ha! I was just kidding around. Glad to help.

check your rep :) :bowdown:

So what do you think of the sound with just the Berk HFC? Sounds pretty throaty with just that one change, doesn't it?

Yeah, it's a nice upgrade from the stock sound. While more rwhp is a priority, I'm tired of my car missing some sportscar exhaust note. The HFC alone will be a nice improvement, the Berk CBE make is sound ridiculously good. Still tempted by the Stillen CBE though.

The Berk HFC install seems a bit tricky with those darn bolts. I think I could pull off the G3 intake with no problem though. I have my Dremel ready for the hole cutting.

You will be fine as long as you dont throw a CEL... So my suggestion is get the test pipes that have the non-foulers/O2 sims so you dont have a check engine light.

Ps If you are in Chicago why are you not on the ChicagoZ Forum!!!!!!!!:tup:

You, my friend, need to lean how to lie.

I would tell her you're doing exhaust since it's more expensive, then sneak a little money out of the checking account each week as a cash withdrawl. The cats are only $500 more. Get them done at the same time so she doesn't suspect anything. Then, at Christmas or your birthday (which ever is first), tell her that your car doesn't run right because the intake is too restrictive and wasn't matched to go with your exhaust. The intake may even make it fail emisssions...but it you put aftermarket intakes that are matched to your exhaust, the car will run perfect and pass emissions.

On a more serious note, for $100 or so, you can get a sportscar sound with the stock look. Check out this link as it's quite valuable:

Dude, you're devious. I can respect that. :tup:

The test pipes with extended O2 ports are from GTM, btw. (In case anyone is wondering where to get them.)

Semtex, you can disagree all you want, but the fact of the matter is that changing the tune first will yield good gains. In addition, much of the gains in power from the aftermarket intakes isn't from additional airflow, the stockers flow just fine, it is actually from changing the MAF signal to read less air is flowing and thus leans out the charge to a more ideal ratio. Those disputed tests where the guys at 370z.com held the air-fuel ratio at stock levels proved that the power gained from additional flow was minimal. This points to where the intakes make most of their real power, which is changing the reading and thus the combustion mixture, not from additional airflow. If you were to take a stock 370z and flash it, you will see good gains.

And as further proof, this has been done and tested at 370zdotcom.

Had they gone with a better map, their gains would have been greater.
