My son and I are looking at 1960 Hawk to purchase. Nephew of owner says exhaust "donut" has a hole/leak in it that goes away after car warms up. Can anyone enlighten us to what is a "donut" in the exhaust system? How hard to source and replace? I am not familiar with the term "donut" except with coffee.
