Ask a Question-
Whats is the difference between stainless steel and aluminum in the sound or is it about durability??
Sound difference = minimal to none, both materials produce virtually identical exhaust tones. As for durability, stainless steel is more corrosion-resistant, ideal for harsh climates (salt, snow, moisture) and will last longer overall. Aluminized is more budget friendly, but will be prone to some spot rusting over time, especially in wet or salty environments.
