Why Subarus Sound Deep
Subarus are known for their distinctive deep sound, often referred to as the “Subaru rumble.” This unique sound is primarily attributed to the design of the Subaru boxer engine and the use of unequal length headers.
Subaru Boxer Engine:
The distinctive sound of Subarus is largely due to their boxer engine, which has a horizontally-opposed flat design. This design, in combination with the unequal length headers, contributes to the unique deep rumble that is characteristic of Subarus.
Unequal Length Headers:
The 2.5-liter Subaru engine makes use of unequal length headers, which are a key factor in producing the deep sound. The unequal length headers create a distinct exhaust note that sets Subarus apart from other vehicles on the road.
In summary, the deep sound of Subarus is a result of the combination of the boxer engine’s design and the unequal length headers, which contribute to the unique rumble that is synonymous with Subarus.

What makes a car engine sound deeper?
A cold air intake is one of the best options for getting a resonant, deep-sounding exhaust note from your vehicle. When you rev your engine and finally release the throttle, you’ll hear the sound of air flowing through your intake and changing the notes of your engine to a louder, more aggressive sound.
Why are V8s louder than v6s?
At 6600 RPM, which is a typical redline for a big pushrod V8, the pitch is 440 Hz. 440Hz is, at least for the bulk of people in the world, a really nice musical note. What is the primary difference between a V6 and a V8 engine? As other people have stated, the primary difference is the number of cylinders.
Why do Subarus sound like they are misfiring?
The 2.5-liter Subaru engine makes use of something called unequal length headers, which are exactly what they sound like. The header piping from cylinders one and three are of a different length than those from two and four.
Why do V8s sound deeper?
Because they have twice the cylinder count, a V8 engine’s frequency is in a higher and generally more pleasing acoustic range.
What gives Subaru its sound?
The header cylinders in a beefy WRX STI are set at different lengths. With cylinders 1 and 3 being slightly different in length to 2 and 4 any sound has to move in an unconventional manner through the exhaust and produces the unique rumble.
Why do Subarus make noise?
A tapping sound is the result of metal grinding against metal inside your Subaru’s engine. Your car usually makes this noise if its oil levels are low, causing your engine’s parts to corrode, overheat or lock up altogether.
What makes Subaru so fast?
Subaru uses a “boxer” engine, which is horizontally aligned so that the crankshaft goes right down the center of the car, facing front and back.
Is Subaru a loud car?
Whether it’s the smooth hum of Subaru engines or the roar of the powerful turbo engine in the Subaru WRX STI, there’s bound to be sound when you drive a Subaru.
Why do boxer engines sound so deep?
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 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.
