headers

hey guys
im wondering if u all recommend headers for a grand am, i was told that it will mess up your sensors and ull have many problems if u do, but i dont see that happening....thanks

It shouldn't affect any sensors at all. I don't know what engine you have, and where your O2 sensors are, so there is a slight possibility they might need to be moved a bit...but if you find an aftermarket header(s) for your car, they should be fine.
