The muffler itself looks perfectly clean, but all the pipes are rust color. Magnaflow offer a "rust through" warranty. Basically if it rusts completely through, they would replace but they claim some bs about the outer coating of rust color as "normal". Complete bs of course.

Question:
Can stainless steel rust?
Answer:
Magnaflow uses 409 grade automotive stainless steel. This particular grade of stainless has the tendency to form a protective layer of surface rust in wet/humid/snowy climates or when exposed to salted roads. This layer is superficial and will not ********* the metal itself. It can be removed using soap and water and a steel Brillo or S.O.S pad. In the rare event that 409 stainless steel pipes become rusted through, Magnaflow's lifetime warranty will cover replacement.
