Do Tri-Y headers make more power?
This means that if the collector lengths are right for that engine package and the tube pairings match up well with the firing order, Tri-Y headers can produce improved power over similar four-into-one headers.
Are Tri-Y headers better?
Tri-Y style headers do a good job maintaining flow velocity. Exhaust from one tube rushing past the “Y” can help scavenge air from the other tube. Tri-Y headers often make better low-end torque than similar 4-1 headers.
Do Tri-Y headers sound different?
Tri Ys don’t sound any different than conventional headers.
Who makes Tri-Y headers?
For 60 years, Doug Thorley Headers has been making premium American-made components and the Tri-Y has led the charge.
What does Tri-Y headers do?
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.
Where are Hedman headers made?
California
Hedman Hedders is the original, and still the premier manufacturer of performance exhaust headers in the world. Design and produced in their California manufacturing facility since 1954, no other header manufacturer offers as broad a selection of applications and design options in the industry.

What is the difference between an exhaust manifold and a header?
The difference between them is that an exhaust manifold is a solid cast iron structure across all cylinders while an exhaust header is made up of a series of individual steel tubes for each exhaust port, welded to meet at a collector to bring the exhaust gases down to a single pipe.
What are Tri Y headers?
Can a header be too big?
Too large a header will reduce torque output of the engine and increase the possibility of exhaust gas reversion—again increasing heat. Simply put, torque is related to air velocity (the faster the air/fuel get through the engine), and horsepower to the volume of air/fuel that processes through the engine.
