Mopar 52122572AA OEM Exhaust Hanger Rear Tailpipe Isolator

The Mopar 52122572AA is a genuine OEM exhaust hanger — also known as a resonator and pipe hanger or exhaust support isolator — designed to securely mount the rear tailpipe section of the exhaust system to the vehicle's undercarriage. This direct-fit replacement part maintains factory-specified positioning of the exhaust, preventing unwanted contact between the exhaust system and surrounding chassis components.

Built from durable rubber-and-metal construction, this exhaust isolator absorbs vibration and movement from the drivetrain, reducing exhaust noise transmitted into the cabin and minimizing stress on exhaust system joints and welds. Replacing a worn or cracked exhaust hanger promptly helps prevent premature damage to exhaust pipes, mufflers, and resonators.
