Adding headers?

will adding a set of stillen headers to my non turbo 300zx really dispense me that much more horsepower. It is a 1994 300zx without the turbo and i want to know if its worth the nearly 500 dollars to purchase them. I would resembling to see at least a 12 horsepower gain. Will that be sound to expect that and does anyone else have a set of stillen headers or hear anytthing about them on the 300zx

What to do beside my outdated motor?

Answers: It depends on how restrictive your factory pieces be. If spending 500 dollars is worth 12 horsepower, then you'll probably procure it with the headers. I would a bit spend less than 400 for a Compucar "nitrous within a bag" kit. It's an adjustable up to 100 horse power dry apparatus and is transportable to whatever fuel injected sports car you want to install it into.(rentals, minivans etc....)
