Well bought these headers and ya hear horror stores about fit and leakage so the mechanic who put them on said he didn't have no problems everything went smooth and fit properly lol my fuel mileage did go up a mile a gallon and it feels like I have more power but maybe it's just me thinking I have more power lol ! I think JBA header are built very well and U will be happy with them without breaking the bank !
