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!!!!!!!!

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

HFC's do not have rasp

Some test pipes do at certain rpms

When I had APS TP on my 350z the rasp was from 3200rpm-4200rmp under WOT

But I thought it sounded good I also Had Megan Racing Headers,Borla TD

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

semtex · 06-17-2009, 04:22 PM

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.

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

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.

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

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.

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:

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.

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

I never stated that getting a reflash done first wouldn't yield good gains. Getting a reflash done, whenever you do it, should yield good gains. I simply believe that given the cost of a reflash, if you're planning to do a bunch of bolt-ons anyway, it makes more sense to do them all first, then do the reflash one time, vs. doing it before and then again after and therefore paying for it twice. If the added expense doesn't bother you, or you don't plan to do any bolt-ons for a while (or at all) then have at it. Either way it's your choice. But I personally don't feel like laying out the funds for a reflash twice, given the mod path I've taken.

In so far as the OP is obviously planning to do a bunch of bolt-ons, I believe that it would make more sense for him to do them prior to the reflash, strictly from a cost-control standpoint. In other words, whether or not he'd get good gains from a reflash is not something I'm disputing here.
