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.
