Review on Walker 21047 Quiet Flow Stainless Muffler by Adam Jacobs

I bought one of these 3 years ago when they first came out. After 2 years, rust began to appear on the muffler body at the connection with the end caps. After 3 years it looks like the muffler will rust next year. Obviously it wasn't a fully stainless muffler. A lifetime warranty doesn't make up for the pain of a muffler replacement, and Walker's "SS" label on this product is clearly misleading.
