Make different exhaust pipe sizes work together with this Exhaust Reducer, available in multiple finish and connection-size configurations. Options include aluminized steel or chrome-plated steel designs, with connection sizes such as 6-inch to 5-inch and 7-inch to 5-inch in various inside- and outside-diameter combinations. The reducers are 8 inches long and are designed to connect differently sized exhaust pipes. Chrome versions feature a triple chrome plating process and are listed as rust resistant, while the aluminized steel option is also listed for rust resistance. Each reducer is sold individually and covered by a warranty against defects in workmanship and material from the date of purchase. These are aftermarket replacement exhaust components and are not OEM. Depending on the selected option, the reducer may ship directly from the manufacturer in a separate package, while the aluminized 6-to-5-inch ID/ID version is listed as special order and non-returnable.
