In the early years exhaust fitment centres only fitted exhaust systems, but increased competition over the years changed this trend and more and more fitment centres were compelled to diversify into other product lines.

Through the years De Graaf Exhausts Systems has built up a well-known brand name, but the name was mainly associated with exhaust systems.

Although exhausts still form a major part of a fitment centre’s sales, to compete in this market it is vital to fit and supply a bundle of products.

It was then decided that a different name was needed so that the consumer could associate the fitment centres with other products besides exhausts, yet maintain the advantage of the De Graaf brand name associated with exhausts, hence the name Under-Car.
