Does anyone know if the 97 Contour GL's exhaust pipe is welded on or just clamped?

The exhaust Pipe (Manifold to cat) is fastened with flanges that bolt together. Most of the rest of the system is held together with boltable flanges betweeen the components. Some joints are clamped though. I think the muffler is welded on. You really need to take a look at the diffferent components of your car to be sure.
