350Z - My Return to Stock Headers

I took off my Stillen headers, which I dyno'd to show an 11whp gain at 6500rpm. It was causing a bit of a nasty resonance/rasp at 3200rpm when combined w/ my Stillen exhaust, that is pretty much minimized with the return to the stock manifolds.

Mod list is in the video.
Car is a 2006 350Z 6MT

I'm pretty sure that anyone who read the description and watched the video (including yourself) fully understood what was meant by my abbreviated description of the part and process. It's simply easier and simpler than using the technically correct "exhaust manifold". Thanks for the semantic correction, though. I hope that made you feel better, because I fail to see how it serves any other useful purpose.

I lost the 11hp when I went back to stock, so that means it was a 11hp gain when I put on the Stillens (which are back on as of last month)

@oNAGAo I have the same headers and exhaust and there is a real nasty raspy sound at 3500 rpm. Did you also have this issue? Do have a video of the Z with the headers on? 

[cbeck]

so did you have the 11hp gain with the stock headers or when you put on the stillens?

2006 z does not come with stock headers.. only the HR's!
