Doug Thorley Header Kit - 2RZ/3RZ 2000-2004 Tacoma Dual Cat w/EGR

C.A.R.B. Number: EO# D-540-6

Doug Thorley Headers THY-511Y-1-C tri-y headers deliver the ultimate in performance and gas mileage for your 2000-2004 Toyota Tacoma, 4-Runner. Doug Thorley Headers is the originator of the tri-y header design, which is the most efficient way to increase horsepower and torque over a broad RPM range, and more importantly the range where you use it most. That better exhaust flow produces noticeable gains in horsepower and torque output, while increasing fuel efficiency.

The headers are manufactured using heavy duty 14GA steel tubing, and super flat 3/8 inch head flanges. They are then silver ceramic coated inside and out, which looks great, drastically reduces under-hood temperatures, and creates a strong barrier to protect the headers from the environment.

2000-2004 Toyota Tacoma, 4-Runner / 2.4L-2.7L, stock manifold with dual outlet flange and rear facing EGR tube, 2WD & 4WD.
see 1046095 if your stock manifold has a single outlet flange and no rear facing EGR tube.

Application Notes:
-Fits 2RZ and 3RZ Tacoma's
-Fits 2WD & 4WD
-This header has a dual outlet flange
-This header has an EGR flange on top primary tube
-For non EGR, single outlet flange header see part #1046095

Doug Thorley 3RZ Header July 7, 2016
Reviewer: Mike Brown from San Diego, CA United States  
The header fit like a glove. The ceramic coating is excellent.
Great addition and keeps the under hood temps down. The EGR tube bolted up without issue.
I would recommend this to anyone with this motor.
