In 2015 the far rear resonator / muffler rusted out. It's the one at the far back with one input and two tips. I replaced it with a WALKER 21397 "stainless steel" unit. Guess what? Yup, four years on and it's completely rusted out again. I've got another one coming from RockAuto under warranty, but I'm not sure if it's worth it to have it installed.

Does anyone have any ideas for a more durable unit?

thanks in advance,

Larry

Unfortunately aftermarket exhaust parts, even quality ones don't last like the original exhaust systems do on todays cars.
Product Info:
"100% Stainless Steel muffler resists rust-out three times longer than competitors' premium aluminized mufflers."
"Possibly the last replacement muffler you’ll ever need"
Warranty:
"Walker warrants qualifying exhaust products against defects and wear-out when used on private passenger cars and light trucks under normal operating conditions for as long as such original purchaser owns the vehicle on which they were originally installed."
Notice they avoid "rust out" in their statement. Be happy they are at least supplying the part.
Remember, We are a little different keeping a car so long. Most people have been thru a few cars by now, and we are not even considering replacing our M's
