07/08 350Z Headers. Once I finish the install, I'll let you know. Paid $120.00 for them.

Nissan installed them on the 07/08 350Z HR for a reason. At $100-150 a pair, they are a lot cheaper than the aftermarket one's. I bet the HP gains are close. I'm waiting on some cats before i do the install....

JoTech here in Dallas swears by the Tomei headers as well. Expensive little fvckers though, aren't they.

are you trying to install the headers yourself? If you are, let me know if you need an extra hand, i'm back in SD now and i've worked on a handful of the G/Z's around here.

PLUS the OEM headers are of a much thicker gauge metal which means better heat retention, higher exhaust velocities, lower under hood temps, especially with the OEM heat shields in place. Aftermarket headers make underhood temps skyrocket which is hell on the engine bay, especially wiring jackets and hoses and any of you running open element intakes.

Used Nismo are about 600~700 but they are well worth it.
I really love mine.
Nismo headers perform as good as Crawford but Crawford need to lift engine for installing but not Nismo.

Or you can go with Stillen.
But Stillen, DC, Strup are the same.
They are not true equal length (close enough though).
The only true equal length are Nismo and Crawford and both has true F1 collector.

I'll recommend not using any headers at all if you are using your stock cats.

On this engine, headers have a net zero gain if connected to stock cats.
