Bolt on Tri-Y headers designed to fit 1964½, 1965, 1966, 1967, and 1968 Ford Mustangs with 260, 289 and 302 engines.
Although they look like average Tri-Y headers, these headers have been refined to provide ample clearance around the starter, steering and shock towers for a superior fit.
They are engineered to make strong power and torque throughout the RPM range with mandrel-bent 1-1/2" primaries, 1-3/4” secondaries and 2-1/2" collectors.
Exhaust port size is 1-1/2" x 1-1/4".
Each header is manufactured with heavy-duty features like extra-thick 5/16" laser cut flanges that have been machined flat to guard against warping and heavy-wall 16 ga 304 stainless steel tubing for maximum durability.
This header system includes high quality hardware, premium laminated metal core gaskets, and 2-1/2” – 2” starter tubes with collector flanges for a professional installation.
Note: 1966+ motor mounts are recommended for proper shock tower clearance.
Designed to work with common 157 tooth bell housings.
Larger 164 tooth bell housings will require modification for proper clearance.
Cars with power steering will require DBPP-10961-A power steering ram drop down bracket.
