How to Create a Deeper Exhaust Sound: Tips and Tricks

How Can You Make an Exhaust Sound Deeper?

If you're considering an aftermarket exhaust system, one effective way to achieve a deeper sound is by adding baffles. Companies like Vance and Hines refer to these baffles as "quiet" baffles, but as Kevin Thorpe mentioned, this approach does not render the exhaust quiet. Instead, baffles reduce the ear-splitting high-pitched tone to produce a more deeper note. Don’t be misled by the terminology.

Exhaust science is a well-established field. It's not just about a piece of pipe. Changing back pressure can alter the exhaust note and significantly impact how your vehicle operates, which is something Kevin Thorpe alludes to. Simply saying something is louder does not magically mean it is faster.

I recommend experimenting with baffles until you achieve the sound you desire and then having the bike tuned to optimize its performance.

Using a Grinder

If you're looking for a cost-effective solution, you can use a grinder to modify your exhaust. Get under your car and cut the pipe about 2 inches before the muffler, up to 1/4 of its diameter, and approximately 1/3 of the diameter towards the engine. Keep in mind that this modification may result in a loss of some power. However, you will definitely achieve that lush bass sound.

Attaching a Larger Pipe

Another option is to attach a larger pipe. This approach may work, but it's important to note that it may not be well-received by a significant portion of the population. There's a substantial section of individuals who appreciate big exhaust systems, but the rest, approximately 99.9% of the audience, might find the sound underwhelming and criticize the owner of the vehicle.

The most reliable way to achieve a deeper exhaust sound is by upgrading the engine. With a bigger engine, the deeper exhaust sound comes naturally and free of charge.

Adjusting the Exhaust System

Starting with the headers can have a significant impact on the exhaust sound. Opening headers leading to an H-pipe can produce a lower, more robust sound that adds to the torque. This setup creates a sound that is more reminiscent of a muscle car, particularly if you have a V8 engine.

Next, incorporate some form of resonator, such as glass packs. Avoid using fart cans, like those found on Honda vehicles. Racing several 350Z and 370Z models equipped with such cans proved that it does not sound good, it's annoying, and most importantly, it can be painful if the car is loud enough.

Conclusion

Creating a deeper exhaust sound is more than just about aesthetics; it involves understanding the science behind exhaust systems and making informed decisions. Whether you opt for baffles, a grinder, or upgrading your engine, each method has its pros and cons. Experiment with different techniques and consult a professional to ensure your exhaust setup enhances both the sound and performance of your vehicle.
