I just ordered the NISMO Headers for my 04 Z. They say that I can get 13hp & 13 lbs. torque. Has anyone installed headers for there car? And what does it sound like. Is there that much of a differnece in HP/Torque?

When you put headers on, your exhaust will sound alot better no matter what brand it is. And you will also feel your Z pull better too!

not sure if this still applies, but i heard thta the first series NISMO headers thta came out did not fit the US spec Z because of the steering being on the wrong side and rubbing issues. if you are getting them new you should be fine

B & B makes the headers for NISMO, my original rubbed the steering shaft and NISMO replaced. This was 18 months ago. Sounds great with my NISMO cat-back and Vortech.

DO YOU THINK I WILL HAVE A PROBLEM WITH THE INSTALL AT MY LOCAL DEALER? DO YOU THINK IT WILL RUB THE STEERING SHAFT? I BOUGHT THESE NEW FROM WWW.LEEPARTS.COM

The Nismo headers were *okay in my book. But not worth the money at all. They do give the car a slight stronger feeling down-low. Kinda like they ad just a little bit more torque. If I could do it over again, I wouldn't go with the Nismo's, but rather the Crawfords or something. They are a PITA to install and that's no joke. But heck if I could do it all over again, I could of stayed stock and would of already of been able to afford the APS TT kit LOL. I've learned from my mistakes :)

Your headers will likely NOT rub. That was an older problem that does not really existing anymore. In any case, the rubbing issue was really minor. When installed, the headers would not touch the shaft. However, under load, the engine would lean a little and the header would touch the shaft. It is easily corrected with a swift hit with a ballpeen hammer. When installed, just have your tech look and see how close the two are to each other. I would say that if they are closer than 1/2", then a "hammer mod" is in order. Otherwise, you should be fine.

Speaking of a pain in the a$$ install, Nismos are nothing. Try installing Crawford headers. Now that is a pain (x2 for me).
