Exhaust pipes route the hot gasses coming out of the combustion chambers away from the engine through the catalytic converters and mufflers. Many times the mufflers or catalytic converters may come pre-welded into a pipe assembly.
Exhaust pipes may rust and develop leaks over time, or can potentially become damaged from a collision or other unforseen event.
Replacing exhaust pipes will usually require installing a new gasket or two along with them. Also check to see if new hangars may be necessary.
