Stillen Headers!!!
We ran the 350Z multiple times to make certain the gains are consistent. This is a constant at STILLEN with regards to development of performance products.
There was previous mention of the similarity of our [STILLEN] Headers to the Borla units. The image below is a great tool to study the differences that are visibly apparent. Material consistency would have to be experienced. By this I simply mean the thickness and rigidity of the tubing and flanges.
The dyno runs on the graphs above are from runs using a bone stock 350Z (track model). As you all know, the track model trim differences do not include engine performance. The catalytic converters were stock and ON the vehicle. The Headers were the only mod on the car.

is that with high flow cats or stock cats? why does the header dyno indicate cats and the baseline does not?

Thanks for helping me clear that up.
Cheers!

Any idea if the headers will fit a RHD vehicle. There is an extra market out there, Australia & UK (It's called export $$$$$$$).

We are fond of the Outback but have not fitted these Headers to a Right Hand Drive Motorcar. We have a great Dealer in the UK and might get a chance to fit them that way.

From the pics they look ALOT like the Borla headers and they are nowhere near equal length. I bought a set of the Borlas and I was not impressed. What are the lengths of each of the tubes in the Stillen Headers? I agree with hfm, I doubt that these are going to net 11 hp. but, I am going to wait and see.

Each tube in the STILLEN Header is 15" Long to the collector.
Thanks for the question!

Those dyno runs look very nice, and the headers look great. Much closer to an equal length design than some of the others out there.
Now, here is my only conern:
Most of the Z dyno's I've seen show the car making more power on successive dyno runs. I notice that your comparison graph is showing the base run 002, but the header run 015 or so. Can you post a comparison from one of the first header runs and one of the later base runs if such a thing exists (just so we all know that you aren't taking the lowest base run and highest header runs for the comparison)?
Thanks,
D'oh!

When you get a chance, it would be great to see your testpipes+headers dyno. That would allow us to compare directly to Crawford, since they have not posted a header only chart.
Of course, Crawford was showing about the same games with pipes included...

Is this really a dynojet? Wow those are really optimistic baseline HP #'s for many on this board those (baseline numbers) are not even attained WITH MODS..what gives..obviously a gain is a gain but .....................................
