Stillen G3 intakes: $549
STILLEN : STILLEN Generation 3 Ultra Long Tube Dual Intake Kit
Stillen headers: $786
STILLEN : STILLEN 350Z / G35 / G37 / 370Z Headers
Stillen exhaust: $1575 (Ok seriously, for an exhaust system?! I'd go custom, lol. I think this is where most of the money went)
STILLEN : STILLEN 370Z Dual Exhaust System
So it's now $2910. I don't know how much hfc's are because I can't find them. So I'll give it $300 (is that a fair price? EDIT: **** my life, $570 for hiflow cats...Give me test pipes.). So $3480, as proven should make at least 55whp I added the headers into the equation though so it should be a bit more whp. $700 for the ECU and dyno time. So now it's $4180. For what SHOULD have been over 55 whp as claimed by the company that made the products on phimosis' car. Without a tune.
I don't know where 5gs came in...Labor? And I don't know where his power went. Maybe the guys at Stillen can chime in.
So in a jist, $2697 = 55whp (dyno proven by stillen), WITHOUT headers. Maybe the tune? Lol, I dunno.
