Stillen Headers installed - Review/Pics/Vid/Dyno

370zForever · 02-17-2010, 05:18 PM

Semtex, would u say that the stillen headers are lighter than the stock ones cause I looked at the stock headers and they looked really flimsy....

semtex · 02-17-2010, 05:25 PM

Yes, they're a lot lighter.

370zForever · 02-17-2010, 06:17 PM

Man, you're fast....

Thanks for clearing that up, great set up by the way....

Resonably old thread but FYI, when I return from this business trip I will be installing a set of Stillen headers, my set up will be (exhuast wise) STILLEN coated headers, FI HFC's, EBAY Y pipe, self opened/gutted/straight piped then re sealed muffler.
Ill report back and stick up a vid or two.

I beleive Semtex should be having his headers up for sale, if he didn't sell them already, being that he now has the FI LTH'S!!!! One lucky MF!!!!!

are the intakes good for daily driving in the rain?

Reviving and old thread but looking for some answers as headers seem to be my next purchase.

Semtex, did you ever redyno with the stillen's after a tune? Thanks.

Not sure I understand your question. A tune is done on a dyno, so you're doing both at the same time.

quicksilver08 · 08-22-2011, 12:48 PM

Ya. Sorry bout that. My eyes were going crossed from reading so much on headers. Did you ever returned after the stillens to see if you got better numbers?

semtex · 08-22-2011, 05:21 PM

^No, I don't believe so. It's been a while. I don't even have my Z anymore.

Edit: Just remembered -- I switched over F.I.'s long-tube headers after these and did a re-tune at that point. But there was no re-tune in between.

I just tackled the Stillen Header Install, it took myself and a buddy a full day, i would say 10-11 hrs. It is a PITA, however it is very doable, i wanted to not even start after hearing all the people on here complain like grade school. but im glad i did it myself, saved a lot of money.

To clear it up for anyone else who is curious:
I used the stock gaskets, they are metal, and will do fine.
yes the passenger side is waaaay easier.
You will want a bunch of swivel/ 14mm socket combos
i only used 14mm 10mm and a 12 once or twice.
get a set of rotating-ratcheting wrenches, life saver.
And wear a damn glove.
i by no means am a mechanic, if you can take your tire off, you can do this.

i have to dyno it soon...to see real results

Has anyone who has installed Stillen headers, weighed the stock manifold and the new headers? By calculating from some answers on the weight reduction thread, I've got the stock headers at 16 pounds for both. On this thread it was mentioned that the Stillen headers are lighter, but the actual weight wasn't given.

CLyons0203 · 05-29-2012, 11:39 PM

anybody selling there stock exhaust manifolds?
