I just flipped 100k. There's a rattle that sounds like a loose heat shield but also the slightest bit of "throaty" sound. I'm thinking a failed gasket?

As a general rule of thumb, what's the expected lifespan of a 4cyl Plain Jane 2010 Ranger?

The Ford dealer terrifies me. Any suggestions of ~2010 Ranger exhaust? Replace everything; replace pieces?

Thanks.
