Advanced Exhaust Technologies' Fuel-Saving Liberator Muffler Debuts

16 November 2000

Advanced Exhaust Technologies' Fuel-Saving Liberator Muffler Debuts in Dallas
    AUBURN HILLS, Mich., Nov. 16 The fuel-saving Liberator
muffler by Advanced Exhaust Technologies, the most significant advance in
heavy truck muffler technology since the 1920s, makes its first public
appearance today at the Great American Trucking Show in Dallas.
    In test drives on various Class 8 truck configurations, under a wide
variety of load levels and weather conditions, the revolutionary Liberator
muffler has produced fuel economy improvements of 0.3 miles per gallon to 1.2
mpg.  Most heavy trucks average between 5 mpg and 7 mpg.
    "These rather remarkable fuel economy improvements owe to a unique design
that reduces back pressure, allowing engines to breathe more freely.  The
Liberator is a self-contained noise cancellation system unlike any other in
the muffler industry," said Richard D. Bergesen, President and Chief Executive
Officer of Advanced Exhaust Technologies LLC, (AET) of Auburn Hills, Mich.
    Offered exclusively by AET, the Liberator is made of stainless steel and
is built to ISO 9002 standards by Wellington Industries, of Belleville, Mich.
    On public display for the first time at the Dallas show are two Liberator
mufflers.  They appear in the booth of Truckin' Bozo Radio Network -- WLW,
Cincinnati, Ohio.  On hand to explain how the Liberator performs is inventor
Steve Heuser, of Augusta, Mich.
    Heuser began developing the Liberator's unique design 10 years ago.  The
Liberator is fully patented in the United States and patent applications are
pending in most European countries, Brazil and Japan.
    Diesel fuel is the most expensive cost component for commercial vehicles
that travel about 125,000 miles per year.  It currently costs about $1.60 per
gallon in North America, which is up by 27 percent from a price of $1.26 at
this time a year ago.
    "At current fuel prices, we think the Liberator can save truckers and
trucking companies up to $3,900 per truck per year in fuel costs, depending on
driving conditions and other variables," Bergesen said.
    "AET is the only company in the heavy truck muffler industry that makes
specific mileage claims," Bergesen said.  "And we are so confident in the
quality of our product that we are offering a lifetime guarantee against
manufacturing defects to original owners."
