Find a used one for half the price. Is this your only upgrade or do you have others. No point really putting this on a bone stock engine unless you have other mods. I have a japan manifold that I'll be running with my whites and 19t, only because they're half the price of an R. From what I've read that R manifolds have a higher flow rate, but the Japans have a better flow pattern.

Before getting a new one, you should try playing with your current one. Adjust your exhaust camshaft. They come from the factory with a slight retardation in order to achieve high horsepower in high rpm. If you advance it a little bit (a few degrees) you will have more power in the lower rpm range (more usable power).
