Yeah, I used to have mufflers replaced every two years also before stainless steel became the norm and every other corner had a muffler shop. Now all those muffler shops are gone.
You better hurry with Sears though, they're just down to 21 stores and they'll probably be gone next year. I think there's just one store left in Maryland.
