Insulator

What is an Exhaust Insulator?

Exhaust insulators are used in the exhaust system to isolate and dampen vibrations and noises that are generated by the exhaust system, and also help insulate heat from your vehicle's floor and chassis. Exhaust insulators are made of rubber or a similar flexible material that provides support and reduces the transfer of vibrations from the exhaust system to the vehicle's chassis for quieter operation. The insulator also helps prevent excessive movement and rattling, which can cause the exhaust system to contact parts under the vehicle and damage exhaust or undercar components. Over time, exhaust insulators can deteriorate due to heat, environmental factors, and general wear and tear. When this happens, the insulators may become less effective in dampening vibrations and noise, and you may experience symptoms such as a low-hanging exhaust, loud exhaust noise, or reduced power, acceleration, and fuel economy. Inspecting the condition of the exhaust system and noting any damage or melting of surrounding components can help you determine if you have a missing insulator or loose exhaust hanger. If you're installing a new muffler or exhaust component, always consider replacing the exhaust insulator at the same time to make a lasting exhaust repair.
