does anyone have any experience with this header?

 

I have experience with the gt spec header... I was under the impression that they are very similar.

 

well how was the expierence... lol

 

On the 2.0 motor I lost a little low end and gained some up top. the sound of the car changed too. even through the header is un equal length it is not a unequal as the stock manifold. the result is exhaust note is quieter and you loose a little of the rumble.
