The A90 Supra has made a significant impact in the automotive world, particularly among car enthusiasts and tuners. One critical component that can influence performance and longevity is the downpipe. This article will explore the differences between aftermarket options, specifically the Feeler downpipe, and OEM (Original Equipment Manufacturer) alternatives, focusing on material durability and corrosion resistance.
Understanding Downpipes
A downpipe is an essential part of a vehicle’s exhaust system, connecting the turbocharger to the rest of the exhaust. It plays a vital role in enhancing performance by allowing for better airflow and reducing back pressure. When considering upgrades, the choice of materials used in the downpipe can significantly affect both performance and durability.
Material Composition
Both Feeler and OEM downpipes utilize different materials, which can impact their durability and resistance to corrosion. Understanding these materials is crucial for making an informed decision.
Feeler Downpipe Materials
The Feeler downpipe is typically made from high-grade stainless steel, which is known for its excellent durability and resistance to rust. Stainless steel is favored for its ability to withstand high temperatures and corrosive environments, making it a popular choice for performance parts.
OEM Downpipe Materials
On the other hand, the OEM downpipe is often constructed from mild steel with a heat-resistant coating. While this can provide decent performance, mild steel is more susceptible to rust and corrosion over time, especially in environments where road salt or moisture is prevalent.
Durability Comparison
Durability is a crucial factor in the longevity of any automotive component, and downpipes are no exception. The choice of material directly influences how well a downpipe can withstand the rigors of daily driving and performance use.
Feeler Downpipe Durability
The stainless steel used in Feeler downpipes provides superior durability compared to OEM options. It can endure extreme temperatures and mechanical stress without deforming or failing. Additionally, stainless steel’s resistance to rust ensures that the downpipe maintains its structural integrity over time.
OEM Downpipe Durability
While the OEM downpipe is designed to last, its mild steel construction may lead to premature wear, especially in harsh conditions. Over time, the heat and exposure to moisture can cause rust and corrosion, potentially leading to exhaust leaks and reduced performance.
Corrosion Resistance
Corrosion resistance is another critical aspect that should be considered when evaluating downpipes. The environment in which the vehicle operates can significantly affect the lifespan of exhaust components.
Feeler Downpipe Corrosion Resistance
Thanks to its stainless steel construction, the Feeler downpipe offers exceptional corrosion resistance. Stainless steel is less likely to corrode when exposed to moisture, salt, and other corrosive substances, making it ideal for vehicles that are driven in varying weather conditions.
OEM Downpipe Corrosion Resistance
The OEM downpipe, while functional, is more prone to corrosion due to its mild steel composition. The protective coating can wear off over time, exposing the metal beneath to the elements. This exposure can lead to rust formation, which can compromise the downpipe’s integrity and performance.
Performance Implications
Choosing the right downpipe is not only about durability and corrosion resistance; it also directly impacts vehicle performance. A well-constructed downpipe can enhance horsepower and torque, leading to a more responsive driving experience.
Performance of Feeler Downpipe
The Feeler downpipe is designed with performance in mind. Its high-flow design allows for improved exhaust gas evacuation, which can lead to noticeable gains in horsepower and torque. Additionally, the lightweight nature of stainless steel contributes to overall vehicle performance.
Performance of OEM Downpipe
The OEM downpipe, while adequate for everyday driving, may restrict airflow compared to aftermarket options. This restriction can limit performance potential, especially for those looking to maximize their vehicle’s capabilities. Upgrading to a Feeler downpipe can unlock additional power and efficiency.
Conclusion
In summary, when comparing the Feeler downpipe to the OEM option for the A90 Supra, it is clear that the Feeler downpipe offers superior material durability and corrosion resistance. The high-grade stainless steel construction not only enhances the longevity of the component but also improves overall vehicle performance. For enthusiasts and drivers looking to get the most out of their A90 Supra, investing in a Feeler downpipe is a decision that can yield significant benefits in both durability and performance.
