I am in the mix about whether to get new headers or new cams. which one will i feel the most? And also if i got the zx2.com headers does this get rid of the precats?
Headers will give you more low-end torque, cams will give you more of a mid rpm hp push. Both you can feel. Zxtuner's headers arent out yet to my knowledge though. And no precats on our zetecs. And yes it gets rid of the cat altogether.
we have precats....depending on the header it may be replaced though
if i were you i'd get a header.....if you were to do cams you might as well go all the way and get the port/polished gude or esslinger head packages....they also have a ported/polished tb
