AUTO-JET MUFFLER Corporation has been manufacturing school bus exhaust systems since 1959. There have been many additions to bring it to its current size of about 65,000 square feet. Terry has also built a muffler manufacturing business that manufactures heavy duty all welded mufflers, United Muffler in London Ontario, Canada to compliment the tube bending business.


AUTO-JET MUFFLER has invested a large amount of capital in machinery and buildings with growth and changes in the industry. All of the exhaust systems are produced to OE standards or better, so they are a true bolt on replacement. If it is in the catalog it is available for shipment. We say you cannot sell from empty shelves.


There is a large inventory of add-on accessories to make AUTO-JET MUFFLER the one stop shop for the complete school bus exhaust replacement.
