I got a reply from Adam in regards to the headers:
Hi Bryan,
Here's the skinny as I know it so far:
3.5 headers are in the works for the RWD (350Z & G35) and FWD (Maxima &
Altima) Nissans!
Preliminary testing results have been awesome from what I have heard.
Millen is still testing a few different tube size and length designs for
optimum flow and HP.
Here's some insider info - shhhhhhhhh:-)....
It's likely that the RWD headers will be released first. Road and Track
magazine will be doing extensive tests on the Stillen supercharged 350Z
that Millen wants equipped with headers. We are racing towards the test
date on these for next month.
Expected release date for the Max/Alt headers would be after that (Say
Apr//May?)
We may begin taking "reservations" for these parts in the near future, as
soon as we have pricing available.
I'll share more news with you on this and other stuff when it becomes
available.
Cheers,
Adam
