If you’ve ever had the pleasure of taking a drive in a classic car, you know just how loud they can be. From the exhaust rumbling to engine roaring, classic cars are anything but quiet. But what is it that causes these vehicles to be so loud?

At its core, the noises made by vintage vehicles come down to outdated safety regulations and design decisions. Classic cars are much less likely to have modern insulation or muffling mechanisms built in, making them sound louder both from the outside and inside of the vehicle.

Additionally, calmer engines from years past have been replaced with highly tuned performance versions—leading their own unique sound enhancements through custom headers and modified exhaust systems.

We'll take a deeper dive into why classic cars are so loud and some of the best ways to reduce noise while maintaining your car's original aesthetic. So whether you want to keep your vintage rides as authentic sounding as possible or just need some peace on that Sunday morning ride—we've got you covered!

What Causes Classic Cars To Be So Loud?

note while driving their classic car, others may find it too much to bear!


A brand-new car can leave the lot without generating any noise at all. Purchasing a new car is one of the most excellent experiences since everything works perfectly and seems like it may last for a long time. However, as cars age, they also get noisier. Do older automobiles become noisier? This is precisely the case and for a range of reasons.


There will always be some mechanical wear and tear, regardless of how carefully someone knows how to take care of their car. Keeping track of the many components that make up the motor is critical to the servicing procedure. All these components must wear out over time for an automobile to function correctly. Serpentine belts, for instance, will begin to deteriorate.

The camshaft will time out due to timing belt wear and extension. When this occurs, a significant amount of noise might be challenging. The valve system is most likely where the noise originates from in a motor that is starting to grind.


When a car ages, the motor alone won't always make it noisy. Other automotive components that can cause a failure must also be fixed for the vehicle to function correctly.

The muffler may become slightly less reliable over time or may be coping with a significant carbon accumulation. In addition to making things noisier, it also causes problems with the exhaust by returning pressure to it.


The exhaust is the only reason for the change in sound. It has a particulate filter, a catalytic resonator, and resonance. Due to regulations governing gasoline and noise emissions, all of these are efficiency and noise killers. Any car will sound much more potent if you remove all that stuff.

Fixing a noisy exhaust system on a classic car isn't that different from fixing an exhaust system on a more recent one. In both cases, you'll need to identify the source of the problem and then determine how best to address it - whether it's replacing worn parts or repairing existing components. While some people might enjoy having an extra loud engine


There are a few more factors that make classic cars so loud. One of the most common causes is CV joint noise, which can be caused by worn or damaged parts in the car's suspension system. Other common sources of noise include water pump noise, belt noise and heat shield noise.

Bad ball joints and worn control arm bushings can also cause excessive wind noise in classic cars. Faulty stabilizer link-pins can generate uncivilized sounds when driving over bumps or uneven terrain.

Other Ways To Reduce Noise From A Classic Car

If you're a classic car enthusiast, you know that engine noise can be an issue. Thankfully, there are some easy ways to reduce the noise from your vehicle. The Hoodliner, a product by Dynamat, is one of the best solutions for reducing engine noise in diesel engine compartments. It's a custom thermo/acoustic liner specifically designed to reduce unwanted noise in vehicles.

Another great way to reduce noise is with a product from Second SKin called the Luxury Liner Pro – this sound deadening material is perfect for keeping the temperature down while also reducing unwanted sound. Closed cell foam can also be used as a de-coupler and a thick rubber mat can act as a mass barrier, both of which are effective at making your car more soundproof.

Getting some of these products is a good way to reduce road noise and it won't cost you very much at all. All of these solutions will help make your classic car quieter and more enjoyable to drive around in. With just a few simple fixes, you'll be able to enjoy your vintage ride without the extra noise!
