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 !

Tacoma 2.7 improved

Reviewed By MARCUS D (CORONA, CA) Reviewed for a 2013 Toyota Tacoma —5/9/2017 10:08 PM

Header was well built. Great finish, very pretty. Install was a pain, but I figured it out. The egr housing hits the header flange, so I enlarged the mount holes with a drill bit and it shifted the egr just enough. Install took me 3 hours and I am an experienced mechanic. First test drive I noticed no difference. After a few fillups and the computer adjusted and get better pedal feel and little better fuel economy. Even with the hassle of the install, no regrets.
