Auto-jet is also your muffler manufacturer and mandrel tube bending fabricator, primarily for exhaust, air intake and coolant tubes. We are able to meet Tier IV emissions materials compliance in our assemblies. Auto-jet has also built a muffler manufacturing business, United Muffler in London Ontario, Canada to compliment the tube bending business. Auto-jet has been manufacturing school bus exhaust systems since 1959. There have been many additions to bring it to its current size of about 100,000 square feet. Auto-jet 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. Our quality is excellent. We have state of the art CNC benders and laser measuring equipment.
