Can anyone out there with headers on their car that can give me their opinion that if they are worth changing on the Z or if the stock ones are fine.

Thanks

I put the NISMO headers and there was definitely a noticeable difference on the high end. In combination with an exhaust and intake I don't think you can go wrong.

 

Haven't put them on the car just yet, but I've never been dissapointed after putting them on any car I've owned. I've talked with the company who makes all exhaust for Nismo USA (they are local to us, and requested to remain anonymous), and they said that it was adding about 10 H/P on a stock setup. Numbers will increase a bit with full exhaust and intake.

 

Finished installing my Nimso headers today. Took almost 15 hours for me to do it with jack stands, and a few problems (i.e. stripped bolts). I now have the Injen exhaust and CAI intake, Crawford Cats, and Nismo headers. I went for a little test frive tonight, and can definitely say that their is a big difference. Car pulls much much harder now, and is pretty damn loud as well.

 

A few posts have already stated that B&B makes the Nismo headers. So much for remaining anonymous. hehe!
