Do UEL headers add horsepower?

However, both headers will increase performance over stock, and both typically increase the sound of the exhaust. On most street driven applications, the increase in cylinder temperatures seen with a UEL Subaru header is negligible.

Why are UEL headers bad?

Your OEM EL header system will perform worse than the UEL one because both ports kinda collide at a Y intersection. The exhaust pulses will hit eachother as they meet. UEL headers have the same Y intersections and the same amount of them that EL headers have.

Are STI headers worth it?

Headers are worth the money, they have shown improvement on power time and time again (APS for example).

What does UEL header mean?

For those who are new to the aftermarket scene, UEL stands for unequal length headers and EL stands for equal length headers. We will make it as simple as possible to explain the differences and benefits of a UEL versus EL headers exhaust setup for the Toyota 86.

What are UEL headers?

For those who are new to the aftermarket scene, UEL stands for unequal length headers and EL stands for equal length headers. Choosing the right type of headers and the correct exhaust setup is very important because it will prevent a lots of headaches down the road.

What are equal length headers?

The equal length header is characterized by having all runners be the same length, hence the name. That means the exhaust gasses travel the same distance before they merge into the collector.

Are aftermarket headers worth it?

The answer is yes, headers will boost performance – IF your vehicle is “prepared” for them. We discuss header types, their benefits, and conditions necessary for best results.

Can a Subaru header be used on an UEL Subaru?

On most street driven applications, the increase in cylinder temperatures seen with a UEL Subaru header is negligible. At the end of the day, it’s completely up to you the owner of the car which will be better suited for your application.

Which is louder a UEL header or an equal length header?

The shorter runner on a UEL header will create a louder noise than a longer runner as it has less piping to travel through. This results in the iconic Subuaru Rumble. This rumble doesnt exist on cars running an Equal Length header

What are the benefits of equal length headers?

This results in lower cylinder temperature on an equal length header, which can help prevent ringland failure. Another benefit of equal length headers is the balance of backpressure at the exhaust ports, which will improve volumetric efficency and overall top end performance.
