Hey I'm wondering if its better to stick with the stock B16 Si manifold or to throw on a 4-1 header. I'ver heard the since the manifolds hold heat better that they actually produce more horse than a header ( depending on the quality of course) but being that I would just be getting a generick 4-1 header would it be better to just stick with the manifold? Give me your oppinions. Thanks

 

aftermarket parts are always better for performance

 

What are your plans for the car though?

 

I'm just keeping it naturally aspirated. I've got a blox intake manifold and throttle body and cold air intake. The car is also chipped. I'm just not sure if I should keep the manifold or go header.

 

header all the way.
you already have the intake manifold

 

Well if you want to get a header sure, but don't expect a lot of power from it right now.

 

dont go any thing cheap for the headers. i recommend the skunk2 or dc sports 4-1. i have a si as well and was actually thinking of putting in the Integra type r intake manifold. i hear it lines up and is bigger :D.
