Headers, CBE, HFCS
 

I was just thinking about something I want to do, but want to make sure it will work. I currently have a borla CBE and I want to put on Berk HFCs and stillen short tube headers, WILL IT FIT , when they go to install? Because I know the xyz pipe won't fit with berk HFCs. Thanks for the help!!

So you're still considering the Stillen headers I see

Yes, I know it may not be worth it, but any gain is better than no gain, and long tubes are illegal. And I just want a full setup!

Why not the z1 headers? Z1 headers will require a 350z HFC but it fits and should give you some power gains

Because I'm kind of nervous about putting 350z HFCs on it, and I want either stillen or berk HFCs , since I've heard good things about both and like the way they sound, also the z1s are a little bit out of my price range.

Everybody told u to leave the stock headers alone, not worth it. U probably get better gain from upgraded intake manifold vs stillen shorty.

Yeah we'll don't forget it's what I want to do, not what Everybody else wants me to do!

:drama:

Berk makes 350z cats you could use with Z1 headers

While I agree with members suggestions that gains are very minimal for the expense of header/labor $$$

I might suggest NST lightweight under drive pulleys as an alternative.

The gains will be in line with a short header swap and less expensive altogether.

Hey, it's your money but consider this. How will changing a factory tuned header to an aftermarket header produce any noticeable gains from an already highly tuned engine? You can only squeeze so much power out from this engine. These engines being highly tuned already don't respond the same as for example, a small block chevy would with similar mods. Money better spent on a good tune vice headers. If you want real power gains, go FI.

Fast intentions will make you a catback with HFCs in it so you can run their long tubes and still be legal. That's a far better hp/$ ratio for the same install cost.

How about trying a different approach OP. It's not ALL about producing higher HP. Have you considered modifications to save weight? Z1 has a 2 piece rotor set available at a decent price point. NST underdrive pulley is another good option. How about a lightweight battery?

You see where I'm going with this.

No reason to do headers if you don't install them your selves or you have to run HFC's. Your just robbing yourself. Cost of header install and the restrictions of HFC's.

If long tubes are illegal, I'm sure a header swap with HFCs is too... Actually, I know it's illegal...

Stillen and Berk make HFCs for the 350Z too... The ONLY difference is the flange.

Exactly. If you're going to WASTE your $600+ on Stillen headers I dont understand why you don't save an extra few hundred to get better than stock headers...

The best review I've seen on a friend's car was 7hp... Another friend, +2HP... The dyno reads +/- 5hp anyways...

At this point we've all told the OP it's a waste of time and money for no power. If he wants to go find out himself, go for it.

Ok. Beer time.

Then why did you ask? I second everyone else that it is a waste of your money...

Already have a borla catback, I'm under aged, my mom restricts me on things I can do , she said I can do headers and high flow cats as long as my setup is legal, and she won't let me do weight restriction things.

They're illegal. I guarantee it

What ? Shorty headers and hi flow cats? If that's what you're talking about it's not. Already checked with local pd and the states regulations.

Wow. Then go spend your money on headers that will cost a fortune to install and will make zero power. We've explained it to you over and over. I guess the only thing that will convince you is being out a lot of money and a dyno sheet showing no gains.

Nope. He's right. It's illegal to take off working cats. It's a federal law. Is it ever enforced? No. But it's not legal.

Now it's starting to all make sense...

Yep if I could do whatever I wanted I would get ppe headers

Then why not wait until you're older and can make your own decisions rather then buying POS headers that are worse than stock because it's all you're allowed to do?

Okay I'll explain. I graduate in late May, I wanted to have all my performance parts ready to go before then, because I'm going to drive 8 hours to texas and have my car tuned at JOTECH, so then I will be done with my performance, another issue is I believe the mechanic I want to install my headers, I'm not sure if he will because he won't do anything illegal, (such as removing cats). And if he doesn't, odds are I'm going to pay 560 for headers and 560 for cats or something, (prices aren't the same), and around 360-480$ for install. (60$ per hour),,,(6-8hours)

I also really like louder noises from the exhaust, which I know you said HFCs will have plenty of exhaust note, but will LTH have the same effect?

I am new or the 370z and was dead set on buying headers. After listening to so,e feedback I think It doesn't make sense plus the oem heat shield has to be removed with some do these headers thus creating more heat issues. I just thought it didn't seem worth it.

Is your mom aware that spending your money on the Stillen headers are a waste of money? If shorty headers are what you are looking for wait a little more time and buy the Z1's. You had mentioned that it worries you having to add 350Z HFC's however many have done it. Check out the massively long thread on it.

I think it's worse to spend money on crappy headers that may be less in price but provide very little performance gains then spending your money on headers that may be a little more expensive but at least will make a difference on your car and would totally be worth the installation costs as well. I would try telling that to your mom.

Take your time and do it right. Don't throw your money away which would be buying the crappy headers.

Okay thanks, but if I can't do ppe LTH I'll look into the z1 headers with 350z HFCs? Right? And I just give them a call and they will help me out with what I want to do? Or how do I go about that?

Yep! Go to the Z1 Motorsports website and you can see more about them there. Also check out the thread on here about the Z1 headers. You can call them up and ask any additional questions you may have. Also as someone had mentioned that if you wanted the Berk HFC's you could get the Z1 headers and the 350Z Berk HFC's.

The Z1 headers cost is $895 and from Berks website their HFC's are $499. However the Z1 cats are $358.

Guys, (or the ones who have been here a while)

Let's just back away...

Okay thank you!

Sorry not everyone is 50 years old and knows everything about cars and their upgrades. So go ahead and " let's just back away..." Since you were no help at all to me, Chuck and nismo270 were the only ones that had an impact on my decisions.

Ignorance is bliss.

Call it what you will.

I have the Z1 headers/Z1 cat deletes. Thats the only setup id run with. (Without doing LTH)

I'm not 50 either, I just turned 24. I'm telling people to back away to not bash you. I provided help. Not my fault you cannot see it.

:iagree: Those are the only shorty headers that make any power. Do those and a set of DE HFCs and be done with it.
