So I have been trying to find some headers for my 2003 Acura RSX(Base) and I can't seem to find a good one that ships to California. So I think I am going to go with the DC Ceramic headers and I know they don't give much power, but can you make power out of it with a tune and how much do you think I can gain? Also if you know any good headers for the RSX that ship to California can you please post them below, Thank You.
