The simplest and most obvious way to improve your car's sound is upgrading your speakers. Your factory speakers most likely won't match the quality of a third-party speaker installation. Simply swap your car's speakers for a set with better quality to boost the volume and clarity of your car's sound.
The sound a car makes is literally the 'make or break' point of a car and when you have something that looks great, drives brilliantly, and sounds extraordinarily good, it usually costs more than the average salary. Examples of these include the Lexus LFA, the Alfa Romeo Disco Volante, and the Ferrari 812 Superfast.
Because they have twice the cylinder count, a V8 engine's frequency is in a higher and generally more pleasing acoustic range.
Engine sound also matters for car enthusiasts. Discussing about V8 Vs V12 sound, V12 engines have a firing order from right to left pistons and a 90° crankshaft which makes less sound. On the contrary, the filing order in V8 engines has an irregular firing sequence which increases the sound.

One part that deepens the exhaust sound the most is the muffler. A free-flowing performance muffler which incorporates hair or fiber-like material for absorbing sound from companies like Borla or Magnaflow will provide a deeper tone than the stock muffler or a muffler that uses chambers or baffles.
A good engine should roar, but not too loudly. If you feel your car is more noisy than usual there could be an issue with cylinder compression. If there is an uneven air-fuel ration in the cylinder, combustion can occur at higher or lower rates than normal.
A chugging sound could mean there's a blockage in the exhaust system. [2] A rattling sound might mean it's out of alignment. A hissing sound could mean there's a crack in the exhaust system. Take your car in for an exhaust system check.
The BMW M5, Ford Mustang, and Acura TLX, to name a few, use an active noise control system, which plays pre-recorded engine noises through speakers. Some EVs, including the Porsche Taycan and Tesla Model 3, use fake engine sounds to enhance the driving experience when you press the accelerator.
Engine Design
One of the keys to the smooth revs of Ferrari's engine sounds is the flat-plane design of their motors.
Coupe: Loudest: 2016 Porsche 911 GT3 RS: 108 decibels
At idle, the Porsche makes a discordant cacophony of sounds, but with its gas pedal smashed to the floor, we measured an earplug-worthy 108 decibels inside the car. Its 4.0-liter flat-six is not to be trifled with as the RS approaches its 8800-rpm redline.
The Top Quietest Cars based on low NVH levels
The level of quietness is based on low noise, vibration, and harshness (NVH) levels: Audi A8. Mercedes-Benz S550e. Kia Optima.
Both were used in its most luxurious model line, the Cadillac V-16. Cadillac produced two of only three production gasoline-fueled V16 engines in history. The company has twice since attempted to build a new V16 engine, once in the 1980s and again in 2003 (the Cadillac Sixteen), neither making it into production.
Marine use
MAN V14 engines have been installed on cruise ships such as the Explorer Dream and Norwegian Spirit, both of which have 14V48/60 engines producing 14,700 kW (19,700 hp) each, and on some cargo vessels. However, other major manufacturers do not normally offer medium-speed engines in the V14 configuration.
