For the average person, exhaust pipes seem like a mysterious subject.
It often seems like everyone talks about titanium alloys and carbon fiber for lightweight and performance, while stainless steel is deemed practical but uninspiring. However, exhaust pipes entail a much deeper understanding. Whether it’s for increased horsepower, a stylish appearance, or the best value for money, the considerations for manufacturing exhaust pipes vary greatly depending on the intended purpose. Among these considerations, the choice of material is crucial. Let’s take this opportunity to delve into the materials used in exhaust pipes, so that everyone can select the most suitable option according to their needs!
Steel
Original exhaust pipes commonly use materials like regular ferrous metals, which offer undeniable advantages in terms of price. Additionally, their stable, sturdy, and durable properties make them the preferred choice for budget-conscious consumers.
However, in the aftermarket, exhaust pipes made from ordinary steel are relatively less common. Yet, they can produce a powerful, deep rumble and are easy to manipulate during fabrication, making them popular among enthusiasts who prioritize sound and appearance.
Nevertheless, steel also has an unavoidable drawback: its weight. Those who have attempted to replace exhaust pipes themselves can surely attest to this. The weight difference between steel and materials like titanium alloys is quite surprising.
Furthermore, iron is prone to rusting. Hence, most iron exhaust pipes undergo surface plating or heat-resistant coatings to mitigate this issue.
Steel exhaust pipes are highly recommended for vintage motorcycle enthusiasts and riders who prioritize style over performance.
Advantages: Affordable, perfect match for retro-style bikes
Disadvantages: Heavy, prone to rusting
Nerezová ocel
Stainless steel, a material commonly encountered in daily life, is essentially an alloy where chromium and other metals are added to regular iron, enhancing its corrosion resistance compared to pure iron.
The primary advantage of stainless steel is its resistance to rust. However, beyond this, stainless steel boasts excellent material strength, allowing for thinner fabrication processes compared to regular steel, thus reducing the weight of exhaust pipes.
Moreover, stainless steel offers benefits such as a glossy appearance and a lower cost compared to materials like titanium alloys, making it a great value for money.
In the aftermarket, most front section exhaust pipes are made of stainless steel, highlighting its remarkable versatility. Many manufacturers also offer stainless steel tailpipes. The exhaust note of stainless steel exhaust pipes typically exhibits a higher pitch but with a sense of weightiness.
Stainless steel exhaust pipes are highly recommended for riders who want to customize their bikes to reflect their style without the hefty price tag associated with titanium alloys.
Advantages: Rust-resistant, high material strength compared to regular steel, lightweight, excellent value for money, glossy appearance
Disadvantages: Less visually striking compared to titanium alloys
Titan
In the realm of aftermarket modifications, titanium alloys reign supreme. Most riders are captivated by their lightweight construction and dazzling burnt color appearance.
Depending on the product, titanium alloy exhaust pipes typically weigh only about 40-70% of the original exhaust pipes, providing noticeable improvements in performance during braking and cornering due to their lightweight nature.
Furthermore, while being lightweight, they maintain exceptional material strength. However, this high strength also means that processing them is not easy. Consequently, titanium alloy exhaust pipes are associated with a notably high price tag.
Many leading exhaust pipe manufacturers offer flagship products that are entirely crafted from titanium alloys. The exhaust note of titanium alloy exhaust pipes is often crisp and high-pitched.
Titanium exhaust pipes are highly recommended for riders who spare no expense in pursuit of the highest level of customization.
Advantages: Lightest among all metals, high strength, aesthetically pleasing burnt color appearance, virtually rust-free
Disadvantages: Expensive
Carbon Fiber
Although carbon fiber is typically only used in the tailpipes of exhaust systems, it remains a popular choice in the aftermarket modification market.
Its characteristics include a weight even lighter than titanium alloy, as well as the decorative effect brought by its unique patterns.
Additionally, it offers advantages such as a surface temperature that doesn’t rise easily, and material strength comparable to steel, which makes it a frequent choice in aerospace applications. The sound produced by carbon fiber exhaust pipes is typically deep and carries a sense of weight.
However, carbon fiber also has its drawbacks. Firstly, the processing of carbon fiber is quite complex, resulting in production costs similar to titanium alloy, which can be quite high.
Its weather resistance is also lacking, as carbon fiber is quite fragile when exposed to UV radiation, leading to degradation over time. Therefore, it’s not suitable for riders who often leave their vehicles outdoors for extended periods.
Furthermore, carbon fiber is very fragile when facing impacts in the vertical direction. Depending on the circumstances, instances of exhaust pipe rupture following reversing maneuvers are not uncommon.
Although the material for exhaust pipes has its share of drawbacks, it is highly recommended for riders who pursue extreme lightweight designs.
Advantages: Lighter than titanium alloy, visually appealing carbon fiber patterns, and minimal temperature rise.
Disadvantages: Very fragile against impacts in the vertical direction, high cost, and susceptibility to degradation from UV radiation.
