Why the Tri-Y
Why the Tri-Y? Serious Horsepower that’s why! Invented by Doug Thorley Headers, the Tri-Y header is designed to match the synchronization of the engine firing order, thereby maximizing exhaust scavenging. This design creates the optimum torque and greatest horsepower gains in comparison to any other design.
See why many say our headers are some of the best performance headers out there!
