does anyone know how much these will cost or how many horses they will add - cause from what i have heard is headers for our cars dont add much- maybe im wrong though

 

No one will know until the dynos come out, after the headers are made.

 

Emax95 is the only guy who has tested headers on a 95, or any maxima for that matter. He says his NZ headers had a poor design and possibly multiple leaks. This would easily explain for only a 1HP gain. Stillen said they made prototype headers and dyno'ed at 4HP which would also be not worth the price, but that's just $tealin' talking.

I'd say a very good design and tight fitting headers could give around 8HP to the wheels...but the question comes up 'is it still worth the price tag?'

 

When is the release date on these?
