thanks!

 

what are the gains?

 

From Stillen's Website:

The equal length design of the headers allows better and more efficient exhaust scavenging which contributes to the dyno tested performance gains. Examples:
- 2004 350Z produced 11.5 hp at @ 6200 RPM and 18.5-lb.ft @ 3800 RPM at the wheels
- 2008 G37 Coupe produced 14.5hp at @ 7300 RPM and 12.5 lb-ft @ 4200 RPM at the wheels

 

to the top!

 

Are these also on Ebay? Pics look familiar.

 

to the top! brand new in the box

 

Damn... I'm in the market but won't be able to purchase till July. I'll keep an eye on this sale.

 

It is accurate for once, I did a set huge gains all over.
Especially from launch & top end.
The stock manifold is the same diameter, but the stillen has a better collector 3 pipes into 1 vs the stock had smaller ports.
