What is the difference between long tube headers and shorty headers?
For shorty headers, the port pipes actually merge into a single exhaust pipe in a much shorter distance. For long tube headers, the exhaust pipes are much longer and merge farther out. Because of this, each design impacts back pressure in the exhaust system in a different way.
What are Tri Y headers?
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.
How much HP will long tube headers add?
So how much hp do long tube headers add? If attached to a stock engine, you can expect about 6-9 hp over a manifold.
Are Tri-Y headers worth it?
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 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.
What do headers do for a Mustang?
The exhaust manifold is the first step in the exhaust flow process, but it can be quite restrictive. Replacing your Mustang’s stock manifold with performance headers will improve airflow, which translates to more horsepower. Adding a pair of headers frees up the restrictive factory system.
Do you need a tune for headers?
Long tube headers constitute as a major change for the exhaust aspiration of your vehicle’s engine. To compensate for the added air flow, and the relocation of the oxygen sensors, a new or updated tune is required.
Do Tri Y headers make more power?
Are stepped headers better?
Stepped headers give the benefit of a higher velocity exhaust gas at the cylinder through a smaller tube ID, while allowing the benefits of higher flow capabilities further downstream on the larger tube ID.
