Dynomax 17221 exhaust muffler for the 2009-2012 Chevrolet Colorado V8 5.3L and other vehicles cuts exhaust noise and keeps a deep performance tone. The inlet and outlet are both 3 inch pipe connections.
A louder or rattling exhaust, or a visible hole or crack in the shell, can mean the exhaust muffler is worn out. These signs alone do not prove the exhaust muffler is the problem, since a leaking pipe joint can sound much the same.
The listing covers a wide range of Chevrolet, GMC and Ford models, such as the 2009-2012 GMC Canyon V8 5.3L and the 2008-2010 Ford F-250 Super Duty V8 5.4L or V10 6.8L. If your truck is not named here, open the Buyer's Guide tab and check your exact model and engine.
