I saw first hand that Tony and the rest of the guys at Fast Intentions can have your car up on the lift, remove your stock exhaust, remove your stock cats and headers (even with the demon bolt being a pain), take a lunch break, (swat away annoying customers trying to watch every step) :icon17: Install the headers, and install the CBE, then take a test drive. Pack all your stock parts back in your car, exchange payment, and have you back on your way all in less than 9 hours.

Amazing Sound, Awesome Fitment, Excellent Customer Service

The pita was getting the stock headers off. They have installed many sets and my car was the biggest pita to date. Just my luck. The headers went on just fine. The problem is getting the oem headers off.

If you look at the FI headers, they have 3 long individual runners/pipes that merge into into a single collector just before the flange. If you look at the PPE headers, they have 3 shorter runners/pipes that merge before the flange, and then have a single pipe that runs the last 3-4 inches. My guess, just by looking at them, is PPE did this to stay closer to an equal length on the individual runners, but I am not sure.

Those that have the FI headers and CBE, how is the noise level at cruising speed and "normal" accel? Drone, loud, etc...?

Under normal driving, you don't even notice a difference in the fact you have headers over just having a CBE. The only time you will notice a difference is if you get on it. The tone will be different. But the Volume will be just the same. "Drone" Is subjective, and only experienced around 1800-2300RPM's. Stay out of that powerband and you'll be fine. Other then that, when you want to know they're there... they let you know. The rest of the time, they stay reserved. :tup: The perfect sleeper.

Hi,
I see there are some questions about our headers for the 370Z. Here are a few of the benifits of our headers:

1. Our headers are designed on Solidworks 3D cad software for an accurate equal length tube design.

2. Tube lengths are designed for a specific power range. Just making them long with no specific length in mind is not ideal.

3. Our headers are stepped from 1.75" to 1.875" for increased power and flow.

4. Tubing is 16 gauge mild steel or 304 stainless steel depending on order. We offer mild steel headers as a less expensive option, but have sold many of the stainless versions too.

5. We use REAL racing collectors, not cheap formed tube collectors. Collectors are desgned at a 15 degree merge angle for optimal flow and reduced turbulace.

6. Our 304 stainless headers have 304 stainless flanges. They are 100% 304 stainless

7. We have a lot of experience building headers. We build 20+ header sets a month for 20+ moldels of cars. We have been designing header, exhaust and intake systems since 2001.

8. We use JetHot ceramic coatings. Their ceramic coatings are far superior to genaric ceramic coatings that most header builders use.

We did our initial testing on a stock 370Z with everything else being stock. We welcome others to do dyno testing of their own and post their results.

I haven't seen any headers available for the 370Z that are equal length, tuned or use a merge collector. I feel confident that our design is the best available right now.

We are also working on a 1/2 wave length header that had an integrated 5" round ceramic core cat. Applications will be for the 350Z, 350Z HR, and 370Z.

I can say I am very pleased with the headers and I'm surprised that no one has tried these. I'm the only one I know of that has these long tubes. But there's 60+ with FI. mime are jet hot coated and seemed to be crafted beautifully.

I'd def recommend them from my experience. It also made my exhaust tone much cleaner and sound better. Plus the 21 hp I picked up over test pipes. A flywheel was also added at the same time but good power was gained for sure.

If everything goes well I should have them by the end of this week !
gonna be very busy next weekend with the install and then dyno tune on Monday July 4th

Chuck did your headers throw a CEL?

Nope, no CEL at all...

How many miles do you have on your ride since the install? Thinking of doing a little swap for $hits and giggles

anyone else got any comparisons on ppe vs fi?

Ppe gets my vote as they are equal length and Stepped. I've never tried either (so take my advice with a grain of salt). But I would almost put some money down saying PPE would make more power

Since this is open ended, it doesn't really help...

Do you mean more peak power, or more low end power? Different users might want different results.

from my understanding of both, PPE should have a little more power in the higher powerband than the F.I. but a little less in the lower end

but it wasn't proved yet .. hehe
