Installation Notes

Verify inlet and outlet diameter, flange style, and overall length against the original exhaust before installation. This Walker muffler assembly uses a 2-bolt welded flange inlet and a tip-style outlet, so matching the existing exhaust connection points is important for proper fit. Confirm vehicle year and configuration for the Subaru Outback application before ordering.
