Header/ Exhaust Manifold!!!

I just install exhaust manifold into my car this afternoon. The header is 4-2-1 model. It is for proton iswara manaul 1.3 and the price is RM150.

Havent test the speed yet. I want to see the improvement in pick up speed and top speed. Just nw i drive around, i feel my car more smooth and it improved the respond of the car.
