Ok... I need a whole new exaust system... mines rusted and rattling and .... crap.

I'm looking at the Apexi WS catback system. That seems to be the one I want... now for headers, I'm looking at the DC Sports headers, found a place with some good prices.

What's the diffrence between 4-1 and 4-2-1 (I know 4 pipes to 2 pipes then to one pipe) 4-2-1 is better for lowend torque? Correct?

how about a 2 piece or one piece? What's the diffrence?

And ceramic and polished stainless steal? I'm not really going for engine bay looks... but I would like stainless steal cause I don't want it to rust. Will the ceramic ones rust, are they stainless too just powder coated?

help please?
