Product Details

Common Problems This Muffler Can Address

• Exhaust noise increase from a worn internal muffler structure

• Need for a direct-fit Subaru exhaust muffler replacement

Installation Notes and Tips

Confirm the inlet and outlet configuration before installation, since this muffler uses an offset layout with a 2-bolt welded flange inlet and 1.75-inch outlet diameter. Match the vehicle application carefully for 2017 Subaru Crosstrek, 2016 Subaru Crosstrek, 2012-2016 Subaru Impreza, or 2013-2015 Subaru XV Crosstrek. Because this is a specific-fit muffler, proper alignment with the factory exhaust path is important for sealing and hanger positioning.
