My car’s new exhaust cost me a few hundred dollars, yet the sound is the same as before. It appears to have been a purely aesthetic improvement.
I want to know whether there is a method to improve the sound of the 320D or if I should just give up looking for a better sounding car.
Although these 4-cyl BMWs—of which I own one—can be made louder, deeper, or burblier, to my ears they just don’t sound very nice.
We would need to know what you have, what your restrictions are, and how much more you are willing to spend if you absolutely wanted to accomplish more. For myself, I’d go with the “give up pursuit” choice.
Future inquiries about diesel and/or 4-cyl engines are welcome in these subforums.

How can I improve the sound of my BMW 3 Series?
- Get a more compact muffler. The smaller your muffler, the louder your automobile will be because they are made with loudness in mind.
- Place a specialist exhaust assembly in place. The most straightforward approach to increase your engine volume is to modify your exhaust system.
- Purchase a bigger downpipe. These increase the volume of your car by lowering the exhaust’s backpressure.
- Your exhaust system’s resonator has to be removed. This alters the tone of your car, causing it to make deeper sounds.
Just keep in mind that some counties and states have restrictions on how loud your car can be. Check your local laws such before making any alterations to your vehicle.

Why do BMW engines have distinctive sounds?
It can be scary if you hear popping coming from your engine. This noise in your BMW could be caused by a number of different things. These include soiled spark plugs, old or worn-out air filters, and clogged fuel filters. A clog in the catalytic converter or an issue with the ignition could be more serious problems.
A car’s air filter gives the engine the oxygen it needs for the combustion process. Insects, dirt, and other particles that can impede the engine from receiving oxygen are also filtered out by it. It assists in supplying a good blend of fuel and air to keep your BMW running smoothly.
The performance of a car also depends on the spark plugs. They supply the spark necessary for the air and fuel mixture from the air filter to ignite, assisting the engine in producing the necessary power to drive your BMW. A spark plug makes a popping sound when it is old or worn out because it cannot function at its best.
The fuel filter in your BMW is in charge of preventing dirt and other particles from getting into the fuel, much like an air filter does. These particles can enter the fuel and cause harm if a fuel filter becomes clogged. Even the smallest particle can be disastrous if it enters the engine because it can harm the BMW’s engine and other systems.
Do you prefer the BMW 320i or 320d?
The 320d has a top speed of 225 km/h, which is 10 km/h faster than the 110 kW 320i, and is nine percent more powerful at 120 kW. The diesel starts to generate power at less than 1000 rpm and reaches its maximum power at 4000 rpm, 2200 less RPM than the 320i. The disparities are considerably more pronounced in terms of fuel economy.
BMW 320d’s speed.
The first model in the gasoline lineup is the 318i, which has 154 horsepower. It is followed by the 2.0-liter, four-cylinder 320i, which has 182 horsepower and a 0-to-62 mph time of 7.1 seconds. The 330i uses the same engine but has it tuned to have 254 horsepower and a 0-to-62 mph time of 5.8 seconds.
The 3.0 liter straight-six in the sporty M340i produces 369 horsepower and accelerates from 0 to 62 mph in in 4.4 seconds. All gasoline variants have an eight-speed automatic transmission, and the 320i can be ordered with xDrive all-wheel drive while M340i vehicles come standard with four-wheel drive.
The four-cylinder diesel 3 Series versions, the 318d and 320d, use 2.0-liter engines that produce 148 and 187 horsepower, respectively. All models, with the exception of the 318d, can be equipped with four-wheel drive. The 0-62 mph time in the manual 318d is 8.4 seconds, or a tenth longer in the automatic; in the 320d auto, it is 6.8 seconds.
The 330d, which features a straight-six with 261 bhp, will best suit diesel consumers who care about performance. The rear-drive automobile needs 5.5 seconds to accelerate to 62 mph, while the four-wheel drive model needs 5.1 seconds. The M340d xDrive also uses same six-cylinder engine, which generates 335 horsepower and completes the same sprint in 4.6 seconds.
The four-cylinder gasoline engine from the 320i’s four-door sedan powers the plug-in hybrid 330e, which adds an electric motor to increase its overall output to 249 horsepower. The time from 0 to 62 mph is 5.9 seconds, and the battery is said to allow for 41 miles of pure electric driving.
Due to the Touring estate’s slightly greater weight than the saloon, performance numbers are marginally worse, with 0-62 mph timings dropping by a few tenths. The difference won’t be apparent in everyday life, though.
Despite the opposition to diesel, the 320d will continue to be a popular choice among drivers, and it’s simple to understand why given the superb balance of performance and efficiency it provides. The engine is pretty well-known because it appears in many BMW models, although it has undergone a number of improvements for the new 3 Series. With 187 horsepower and 400 Nm of torque, the eight-speed automatic can go from 0 to 62 mph in 6.8 seconds.
The 320d xDrive has a top speed of 145 mph, which is four mph slower than the rear-wheel drive 320d, and it accelerates from 0 to 62 mph in 6.9 seconds if you prefer your 3 Series with xDrive four-wheel drive.
The 320d from the previous generation was a little too noisy for our tastes, but this new model has been improved, and it is quieter than before, just sounds little grumbly when extended. At highway speeds, the engine is a quiet companion thanks to increased soundproofing and the acoustic glazing. The engine is typically extremely smooth when moving.

Car has been owned for 18 months and is absolutely trustworthy. Excellent performance at a reasonable tax rate for 184 horsepower. Excellent handling is what you would expect. Huge feature set, including a good sat nav. Purchased a car with a service pack that had one year left on it, so I didn’t have to pay for any maintenance during that period. When a car is four years old, dealer maintenance is not too pricey. Constantly pricey run flat tires.
Has the BMW 320d a turbo?
From 2005 to 2007, this BMW 3 Series 320d was manufactured. It belongs to the 3 Series’ E90/E91/E92/E93 generation. With the 2007 BMW 320d, it received a facelift and took the place of the 2001 BMW 320d. It has four doors, a front engine, and a medium saloon with five seats. This 320d’s turbocharged 2 Litre 16v Inline 4 diesel engine (BMW M47D20), which has 161 BHP, has a 62 mph acceleration time of 8.3 seconds and a top speed of 140 mph. With a kerb weight of 1490 kg, it gets an average fuel economy of 49.6 mpg and has a range of 665 miles before needing to refuel. It has a 6 speed manual gearbox or a 6 speed automatic transmission as an option. There has 460 liters of luggage space and a 445 kilogram payload limit. modified on November 22, 2018.
Is the BMW 320d a sport vehicle?
A BMW 320d is still the most popular sporty compact saloon in the UK, regardless of whether you are a user chooser or you make your own automobile purchasing decisions. The seventh-generation automobile must perform well for it to be considered a success. We have already driven some of the more potent models and were impressed. The 320d is anticipated to constitute half of all 3-series vehicles sold in the UK, notwithstanding the trend away from diesel.
The 3 Series is as crucial to BMW as it has ever been, and this G20 generation is especially significant because it is the first of several upcoming mid-sized products that will use the company’s CLAR Cluster Architecture platform technology, which was first introduced on larger models in the lineup. Following the 3 Series, the CLAR architecture will be used by the Touring models, the following 4-series, the all-electric i4, and the crucially important M3 model. This saloon’s result is an up to 50% increase in stiffness in key parts and assistance with a 55kg reduction in overall weight.
How can I get my exhaust to sound more resonant?
A cold air intake is an easy-to-install and reasonably priced accessory that can enhance the sound of your car’s exhaust. Unfortunately, because it is coming from inside your engine compartment, the air that your stock intake pulls in is frequently scorching. Because hot air has less oxygen, combustion in your engine is hampered and won’t work as well as it could. While some aftermarket cold air intakes reconfigure how your automobile draws in air, bringing it from outside the compartment, some OEM air intakes are now engineered to bring air into the vehicle from the outside. Since cold air is denser and contains far more oxygen, it helps your engine operate at its best.
Your engine will sound better naturally when it can operate more effectively. One of the greatest ways to get a rich, resonant exhaust sounds from your car is to use a cold air intake. Air rushing into your intake will cause your engine’s tones to change to a louder, more aggressive sound as you rev your engine and then ultimately let go of the throttle.
How far is the range of a BMW 320d?
But how far is a BMW 3 Series capable of traveling? When maintained properly, you can anticipate your 3 Series to endure between 200,000 and 250,000 kilometres.
How can I amplify the sound of my diesel exhaust?
One of the greatest modifications for diesel or electric vehicles is a sound booster. The Sound Booster simulates the sound of a powerful gasoline engine in your car. Diesel car owners frequently lament the lack of sound from their vehicles, saying that it makes for a dull ride. Some folks have removed every silencer from the exhaust because they listened to unqualified people. Some even go so far as to remove the DPF after converting it to a straight pipe system but later regret their decision owing to drone problems (making the car illegal to drive on public roads). Wouldn’t it be amazing if a diesel vehicle could mimic the thrilling sound of a strong gasoline engine? A Sound Booster is now an option, so that’s good.
Modern diesel cars can be equipped with a sound enhancer to simulate a powerful V8 petrol engine. The components of a sound booster include a module that is connected to the vehicle’s ECU and a sound box that produces the tone. It is simple to install and syncs with the engine so that every acceleration amplifies the sound appropriately.
We have so far installed more than 100 units with excellent performance. It is comparable to a mechanism seen in Maserati diesel cars. Depending on your mood, you can choose from a selection of about five sounds through remote control; turn it off to return to the usual diesel sound. This module’s ability to be transferred to another vehicle is another amazing feature.
Which BMW 3 Series engine is the best?
It’s difficult to criticize any of the engines that are offered in the 3 Series because they all strike an outstanding balance between performance and fuel efficiency. But the M340i xDrive’s 374hp 3.0 liter six-cylinder petrol engine is unquestionably the show-stopper.
It provides plenty of power from low engine speeds and is refined, versatile, and easygoing in everyday driving. It is even capable of 40 mpg or more on a highway cruise. However, if you want to indulge in its performance potential, it can accelerate from 0 to 62 mph in 4.4 seconds, thanks in part to the traction of the four-wheel drive. While you’re performing it, it sounds fantastic as well.
A similarly swift M340d xDrive diesel version is also available. It has a 3.0 liter, six-cylinder engine with 340 horsepower, but should be more efficient, especially on long highway drives.
