Nismo headers i would say around 11-15 rwhp, depends on exhaust and cats! If you want the best headers for the same price, Crawford headers are the way to go, $1050.00 bucks with free billet oil cap!! With the helix test pipes, crawford plenum and headers i gained 25 rwhp throughout powerband, and 40 near redline!

Headers, are the one of the best N/A mods you can get! They airflow is ten times better, I mean have you seen the stock manifold it is so restricted. Although with some headers you may lose torque its worth it. Ive heard that short tube headers actually lose torque. But the hp gain is worth it.

Nismos won't do 11whp. Maybe 7-8whp

1flyz, feel free to PM me if you're interested in the Strup headers. Search around, we've received great feedback and they produce respectable gains - in line with the rest, and better than others. Quality and customer service is what you would expect from such a company also. also backed by a two year warranty.
You could install them yourself if you were motivated - save yourself time and money as compared to getting other sets installed where there have been reports of 10-12 hours of labor, having to lift the engine, drop the tranny, etc.. fitment issues.
These headers fit perfect, and come with extra hardware and step by step install instructions.

Let me know if you have any other questions.

Alphawerks all the way! gave me 21rwhp.
As well they are cheaper than crawfords, nismo - you can get them from avalonracing for around $700.

I love it. There is only 1 thing wrong with it. When i got it from the dealership i didnt notice but in 1st gear it sounds weird. Like something is loose and rattling. When i push in the clutch from 1st to neutral it makes a clunking noise. and then rattles up front. Really weird. And also the place where i bought it. They forgot to put in the back right bolt to the wheel. lol Other than that its pretty quick for stock. Faster than my Lexus was stock. Im happy with it. There are alot of pros and cons from my Lexus to the 350Z
