to see how much power gained. I also got the crawford cats
The install was 10 hours, but fitted nicely, no bolt alignment problem

I will open a box tomorrow and find out. Jeff

Jeff or Jason. Did you guys check the new batch of nismo headers vs. the old batch of nismo headers for any markings. That is the only thing holding me back from getting nismo headers. So far the borla and crawford headers have gotten no complaints on rubbing.

The only good reason to buy them, as the dealers can't give you grief about having them - per warranty.
Other than that... ?

Well, the Crawford headers are no where near similar in design to the Borla headers!! Longer tubes, equal length etc.. I wish I had a chassis dyno somewhere close that I could strap on to because these Crawford Headers have made a huge difference on my car. I am not talking about a little change that is hard to really tell like an exhaust, I am talking "Holy Sh$t my car has ***** now!!" kinda change. It is hard to believe I am driving the same car now. My hunger for more power has been satisfied for a while longer with the addition of the Crawford Headers. I can't imagine what the car will feel like with the proper TS ECU reflash.

Sutherlin Nissan in Georgia has a full R tune 350z(Headers,Cams, flywheel, Suspension, wheels, and intake) in there parts department viewable by the public. I have been told that they are getting into Nismo products heavily. So I dont mind a Nissan dealer giving me grief about their own products from their racing division. If a dealer does give me grief I move onto the next dealer who does support their products (like Performance and Sutherlin). Plus I know enough folks to get help with any problems I have with my Z.

And we do build and sell race cars too

I'm not hacking on one or the other, I'd just like to be sure before a decision is made.

Also, there appears to be a lot more welds on the Crawford compared to Nismo, how does that effect long term durability?

With exhaust gasses the way they are the outside is the more important part to get protected. Hi-temp powder coat will withstand the heat of the headers. But jet hot looks awesome, thats for sure!

I've had the heat coating done on a previous RX-7 TT manifold. Worked really well etc... However, I feel that depending on the coating to prevent corrosion goes beyond it's functionality scope, which is mainly to retain heat. Regardless, corrosion is only part of the issue.
The price of these header (especially when converted to Canadian pesos) demand more than just performance, I'd like to see durability especially when you consider the cost of installation on the 350Z. As far as I know (and in metalurgy it isn't much), stainless not only corrodes less, but is stronger, less stressed from thermal fluctuations, and lighter (although weight is marginal in this case). Further exasperating this concern of durability, it also appears that the Nismo have less "pieces" to make an equal length setup (although apparently shorter and a little less HP than the Crawford). Typically welds are the weakest link no?
Right now, until someone can tell me otherwise, the Nismo headers appear to be the better setup for my needs. They cost a few hundred less (more like $500 Cdn) and loosing a couple hp is worth it if I don't have to get a new set of mild steel headers every 3-4 years.
Cool board BTW, I like the feedback one can get here.
