Don't let extreme weather in when you can let the exhaust out. Here's a safer way to work with a running engine in the comfort of a closed garage. The per- manent cast aluminum outlet (installs on garage doors up to 2in. thick), hose adapter completely seals tailpipes up to 2 1/2in. dia. Security chain prevents accidental disconnections. Available for single or dual exhaust systems. Don't trust your safety to anything less.
