1964-1967 C2 Muffler Hanger Insulator - Rubber Isolator Pad
Restore Factory Support with Original-Style Rubber Isolator
This rubber muffler hanger insulator is a direct replacement for the OE-style pad used to cushion and support the exhaust hanger bracket on 1964–1967 Corvettes. Designed with prepunched holes for easy installation, this insulator restores vibration control and support for the rear muffler hangers—ideal when rebuilding a factory-style muffler support bracket. Each insulator is die-cut for consistent fit and made from durable rubber that mirrors the original GM design.
