The engine in the Envoy is powerful and produces a lot of noise while it is operating. The muffler is an essential part of the exhaust system that dampens the noise that is made by the SUV. The muffler is attached to the intermediate pipe on one end and the tailpipe on the other end. Exhaust and noise from the engine has to pass through the muffler before going out of the tailpipe. Inside the muffler is a resonating chamber and the pipes are lined with perforations. As the gas and sound waves bounce around this chamber, the perforations create destructive sound interference. This cancels out much of the noise created by the vehicle and then the gas goes into the outlet to be released through tailpipes.


They are available for the following GMC Envoy years: 2009, 2008, 2007, 2006, 2005, 2004, 09, 08, 07, 06, 05, 04. This part is also sometimes called GMC Envoy Mufflers.
