Hey guys, I'm new to this forum and would like to know some advice on headers as I'm planning to get headers for my car. Looking for some horsepower.

yes, easy fix is to relocate/extend your second o2 behind your second cat. works 100%.
did a writeup on my thread a while back.

Just wondering would headers cause any problems to the engine/motor in the long run ? :s

you already have a header on the car, its just stock. aftermarket usually just gets rid of the cat and replaces it with a flex pipe allowing more air flow. also depends on the design if its 4-2-1 or 4-1, for different power ranges. but even that is not too noticeable unless you do alot more to the car.

it may cause problems if you run catless/straight pipe all the way and no tune and you push on it every stop light. having some back pressure for a daily driver is important. depends on how you treat your car.

OP your best thing to do right now is to do research. Read lots before you slap parts on your car. The more you know the better understanding you will have of which part does what and how it works.
