Doug Thorley Headers Reviews


Purdy Headers!

Reviewed By Bob B (Tacoma, WA) Reviewed for a 2000 Toyota Tundra —1/3/2018 6:11 PM

I ordered these and they arrived well packaged and quickly. I had a shop put these on for me along with some Magna-flow catalytic converters and a Flowmaster cat-back system, so I cant really comment on how hard they are to put in. I do want to say that they did not come with new exhaust gaskets for either end of the headers. I noticed a definite increase in horsepower and engine response, but I replaced the whole exhaust from the block back. Overall I give em 4 stars (a bit expensive)

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.
