Abstract
A cover for insulating exhaust systems of internal combustion engines comprising a tubular shaped layer of insulating material circumscribingly engaging the exhaust system and a flexible metal sleeve for protecting the insulating material and holding the insulating material against the exhaust system. The present invention is held in place using mechanic's wire or steel tie wraps such as a hose clamp. The present invention can also be varied for use in retrofitting existing exhaust systems. In this manner, the insulating layer and flexible metal sleeve are made of sheet material which can be wrapped around the installed exhaust system without necessitating removal of the system.
