They look and feel sturdy as hell. This car had flowmasters hanging on by a thread under it. I remember wondering at that time if they still made Thrush mufflers. When I was getting ready to buy an exhaust, I read the Jegs kit was good but their mufflers where crimmped not welded. A few people suggested listening to some stuff on YouTube. We did and my son was determined we choose Thrush. They just sound like what hotrods used to sound like when I was a kid...
