Installing a custom exhaust system on your vehicle can greatly enhance its performance and sound. But, with so many options available in terms of tubing sizes and materials, it can be challenging to determine which one is the right fit for your needs. In this blog post, we will explore the different sizes of exhaust tubing and how they affect the sound of your vehicle. Exhaust Tubing Sizes Exhaust tubing comes in various sizes, typically ranging from 1.5 inches to 3 inches in diameter. The diameter of the tubing affects the exhaust flow rate, which in turn affects the performance of your vehicle. Smaller diameter tubing (1.5-2 inches) is suitable for low-powered vehicles, such as economy cars or small displacement engines. The smaller tubing size restricts the flow of exhaust gases, which creates back pressure that can improve torque at low RPMs. However, this restriction can also limit the performance of high-powered engines by reducing exhaust flow. On the other hand, larger diameter tubing (2.5-3 inches) is better suited for high-performance vehicles with larger engines. The larger tubing size allows for greater exhaust flow, reducing back pressure and allowing the engine to breathe more efficiently. This increased airflow can lead to improved horsepower and torque at higher RPMs, but may sacrifice some low-end torque. Exhaust Tubing Materials Another factor to consider when selecting exhaust tubing is the material used. The most common materials used for exhaust tubing are mild steel, stainless steel, and aluminum. Mild steel is the most affordable option, but it is prone to rust and corrosion over time. Stainless steel, on the other hand, is more expensive but offers better corrosion resistance and durability. Aluminum tubing is the most lightweight option, making it ideal for racing applications, but it is also the most expensive. Exhaust Sound The size of your exhaust tubing can also have a significant impact on the sound of your vehicle. Smaller tubing sizes generally produce a higher-pitched, more aggressive sound, while larger tubing sizes create a deeper, more resonant sound. If you are looking for a more aggressive sound, smaller diameter tubing can help achieve that. However, keep in mind that this can also create more interior cabin noise and may not be suitable for daily driving. Larger diameter tubing can produce a more refined exhaust note that is less intrusive to cabin noise, but it may not have the aggressive sound that some drivers prefer. Conclusion When it comes to selecting the right exhaust tubing size for your vehicle, it ultimately depends on your desired performance and sound preferences. Smaller tubing sizes may provide better low-end torque for smaller engines, while larger tubing sizes can increase high-end horsepower for larger engines. The material used also affects durability and corrosion resistance. And, lastly, the size of the tubing can affect the sound of your vehicle, with smaller tubing creating a more aggressive sound and larger tubing producing a more refined exhaust note.
