Advanced Exhaust Technologies Offers Money Back Guarantee To Purchasers of Fuel-Saving Liberator Muffler

    AUBURN HILLS, Mich., Nov. 27 Advanced Exhaust Technologies
LLC (AET) today announced that independent Class 8 truck owner/operators who
purchase AET's new fuel-saving Liberator muffler with cash, checks, or credit
cards are eligible for a 30-day money back guarantee.
    In test drives on various Class 8 truck configurations, under a wide
variety of load levels and weather conditions, the revolutionary Liberator
muffler has delivered fuel economy improvements of 0.3 miles per gallon to 1.2
mpg.  Most heavy trucks average between 5 mpg and 7 mpg.
    "We are doing what we can to take the risk out of buying our new Liberator
muffler," said Richard D. Bergesen, President and Chief Executive Officer of
AET.  "Many independent owner/operators are under financial pressure due in
part to a considerable increase in the last 18 months in the price of diesel
fuel."
    "At current prices, we think the Liberator can save independent
owner/operators up to $3,900 per year depending on driving conditions and
other variables.  We think that fuel cost savings in the first few months of
ownership will more than pay for the $950 price of the Liberator.  From then
on, fuel cost savings go right to the bottom line of the owner/operators,"
Bergesen said.
    The Liberator's fully patented design represents the most significant
advance in heavy truck muffler technology since the 1920s.  It dramatically
reduces back pressure, allowing engines to breathe more freely, enhancing
engine performance.
    Offered exclusively by AET, the Liberator is made of stainless steel and
is built to ISO 9002 standards by Wellington Industries, Belleville, Mich.
    The Liberator made its public debut earlier this month at the Great
American Trucking Show in Dallas, Tex.
    "We are introducing this product at a time when many independents are
reeling from the affects of higher fuel costs," Bergesen said.  "Since June,
1999, the price of a gallon of diesel fuel has jumped from $1.07 to about
$1.60.  That is an increase of about 50 percent."
    "We think the Liberator can help all truckers, independents and fleets
alike.  We have so much confidence in the product that we are backing it with
a money back guarantee to independents who buy it and aren't satisfied with it
after using it for 30 days," Bergesen said.
    AET is the only company in the heavy truck muffler industry that makes
fuel economy improvement claims for its product.  It is also the only company
in the industry that offers original owners a lifetime guarantee against
manufacturing defects.
