Getting ready to buy Headers and X pipe from American Racing Headers. My question is since the car only has 4k miles on it, and a lot of warranty left.

Would you go with a Catted X or Without?? I do not have to worry about emissions inspections in the county I live in, at least not at this time anyway.

Would love to do the Ghost Cam tune, but also hate to void the warranty on a brand new car.

Looking for opinions of those who have done it either way.

Thanks in Advance Guys!!
