Bolt-on horsepower and torque with Scott Drake Tri-Y headers. These headers are designed to fit 64-68 Mustangs with 289 and 302 engines with automatic and manual transmissions. Although they look like average Tri-Y headers, these Scott Drake designed 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 tubing for superior durability. These headers are then finished in an extreme hi-temp silver ceramic coating for the ultimate thermal protection. 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 part # DBPP-10961-A power steering ram drop down bracket.

Features:
  • Precision engineered and mandrel-bent to ensure an exact fit
  • Mandrel bent tubes for improved exhaust flow
  • Superior construction for high performance.
  • Ceramic siler finish
  • Gaskets and mounting hardware are included
