Why do Subarus sound so good?

Why do Subarus sound so good?
Subarus, especially the WRX, are known for their distinctive and appealing sound. The unique sound of Subarus can be attributed to a few factors. One of the main reasons is the design of the engine and the unequal length headers used in Subaru’s boxer engines. The horizontally-opposed flat-4 engine design, combined with unequal length headers, creates the infamous Subaru rumble that many enthusiasts love . The unequal length headers result in a burble-type sound, which is different from other cars with equal length headers. This unequal header length setup is also believed to be the cause of some reliability problems in WRX engines, with one bank of cylinders getting hotter than others.
It’s worth noting that the sound of a car can also be influenced by other factors such as the exhaust system and the firing order of the engine. However, the distinct sound of Subarus is primarily attributed to the design of their boxer engines and the use of unequal length headers.
Overall, the unique sound of Subarus, particularly the WRX, is a result of the combination of the horizontally-opposed flat-4 engine design and the unequal length headers used in their engines .

Why are Subaru Foresters so loud?

The Forester has undergone some massive styling and technology changes over the years, but the Boxer engine still remains.

Why do Subarus sound so deep?

The header piping from cylinders one and three are of a different length than those from two and four. This means that the exhaust gas coming off the engine has to move different lengths, and the sound produced does as well. The sound is unevenly spaced in the exhaust and it exits the car as such.

Why do Subaru owners love their cars?

Another factor that plays a big part in Subaru’s outstanding brand loyalty is the consistent reliability that Subaru vehicles provide. A recent iSeeCars report on the most reliable car brands gave an honorable mention to Subaru, highlighting their safe vehicles and strong brand loyalty.

Why are boxer engines so loud?

The header piping from cylinders one and three are different in length from those from two and four. This means, the exhaust gas coming off the engine has to move through different lengths, as does the sound it produces, which creates an uneven tone (much like a rumble), instead of a smooth tone.

Why don’t people like boxer engines?

On one hand, the boxer engines provide an unmatched performance to a sports car. However, the wide configuration makes it a bit hard to work on these mechanically. Besides, the obstruction of airflow they create in the engine area might even lead to their failure at high speeds.

Why do Subaru engines rumble?

And Manufacturing costs down. And they’re also typically lighter however this is also the primary. Reason as to why Subaru. Engines sound the way that they do this unequal length header or manifold.

Why do boxer engines last so long?

Longevity and safety
The Boxer engine’s horizontal design and balance cause the engine to produce less vibration as the opposing pistons move. This adds to the engine’s durability and allows the Subaru to last longer and emit less noise by running smoother.

What makes a boxer engine rumble?

As you heard at the beginning of the video. And I’ll play another clip at the end. So with equal length headers.

Why do Subaru engines knock?

Your Subaru will have a recommended octane rating. If you fill it up with gas with an octane rating that’s below the manufacturer’s specs, you may hear a knocking or pinging noise coming from the engine. If you’ve filled up with lower-octane gas, you can try adding an octane booster to stop the knocking.
