Flowtech Tri-Y Header - BLACK
Shelby sound. Tri-Y torque. These Tri-Y headers were originally designed for the 1965-1966 Shelby GT350 - 289 HiPo; 4-speed manual; manual steering. Over the years Ford enthusiasts have run them in dozens of other vehicles chasing that exact sound and performance. The design is why. Mandrel-bent tubes hold consistent diameter for smooth flow; increasing the cylinder scavenging effect and improving how the engine breathes. 1-1/2 inch primaries feed 1-3/4 inch secondaries into a 2-1/2 inch collector. 3/8 inch flanges for a leak-free seal. Heavy duty 16-gauge tubing. Premium aluminum gaskets in the box. Finished in black.
Install Level: Moderate
Fits 1965-1970 Ford 260/289/302 V8 engines.
Originally designed for 1965-66 Shelby GT350 Mustangs with a 289 HiPo; 4-speed manual and manual steering.
