I have a 2005 Subaru Legacy wagon with 190k. The exhaust(original) has a tiny hole in a pipe that looks like Y and splits to the two mufflers.
Can some thing like this get repaired or do you have to replace the entire exhaust?
If the rest of your exhaust system is in good condition, a muffler shop can replace just that Y-shaped piece of exhaust pipe for you.
Be sure to get that fixed as it can allow unhealthy exhaust air to get into the passenger compartment.
