The Vibrant Performance 2808 Tubing is made from aluminum, and while aluminum is a lightweight and corrosion-resistant material, it is generally not recommended for exhaust systems, especially in high-temperature areas such as the exhaust manifold, downpipe, or near the catalytic converter. Here's why:
Key Considerations for Exhaust Use:-
Heat Resistance:
- Aluminum has a lower melting point (around 1,220°F or 660°C) compared to materials commonly used in exhaust systems, like stainless steel or mild steel. Exhaust gases, particularly in performance vehicles, can reach temperatures well above 1,200°F, especially near the engine, which could cause aluminum tubing to warp, weaken, or fail.
-
Strength:
- Aluminum is softer than steel and can be more prone to deformation under the stresses of an exhaust system, especially in high-heat and high-vibration environments.
-
Corrosion Resistance:
- While aluminum resists corrosion in most environments, the heat cycling and exposure to moisture and road salts found in exhaust systems can cause aluminum to degrade faster than stainless steel, especially if it is subjected to long-term use in harsh conditions.
- Cold Air Intakes: Aluminum is an excellent choice for intake systems because they don’t encounter the high temperatures seen in exhaust systems.
- Intercooler Piping: Aluminum is also common for intercooler piping due to its lightweight nature and ability to dissipate heat effectively at lower temperatures.
- Stainless Steel: Grades like 304 or 409 stainless steel are far more suitable for exhaust use due to their high heat resistance, strength, and durability.
- Mild Steel: Often used in custom or budget exhaust systems, though it can rust over time without protective coatings.
While the Vibrant Performance 2808 Aluminum Tubing is excellent for many applications in automotive performance, it is not ideal for exhaust use due to its lower heat tolerance and strength compared to materials like stainless steel. For exhaust systems, especially near high-heat areas, stainless steel or specialized exhaust-grade materials are a much better option.
