What Makes an Exhaust Parts Manufacturer Different From a Distributor?
A distributor buys from manufacturers and resells. An exhaust parts manufacturer makes the part. Auto-jet has been making school bus exhaust parts since 1959. When a part is older or hard to find, distributors come up empty. We still make it.
