as long as you have them installed past the OEM cats. which i bet you do. then you will be fine getting headers. a lot of people run cut outs with headers. you will gain a lot of power and a lot of sound.

if you get a cat back borla exhaust you would need to reinstall. but if you get headers and borla muffler no need for reinstall.
