Advanced Exhaust Technologies' Liberator Muffler Boosts Power

13 December 2000

Advanced Exhaust Technologies' New Liberator Muffler Boosts Power in Older Trucks
    AUBURN HILLS, Mich., Dec. 12 The fuel-saving Liberator
muffler from Advanced Exhaust Technologies LLC (AET) breathes new life into
older trucks, adding from 5 horsepower to 15 hp and eliminating turbo lag, the
company said today.
    In test drives on various Class 8 truck configurations, under a wide
variety of load levels and weather conditions, the patented new 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.
    "Improved fuel economy is a primary benefit of the Liberator," said
Richard D. Bergesen, President and Chief Executive Officer of AET.  "But
drivers of older trucks tell us that they have experienced a noticeable
increase in engine power with the Liberator."
    Will Treaster drives a 1994 model Ford Class 8 truck with more than
300,000 miles on it.  When Treaster replaced the truck's old muffler with a
Liberator, he said he noticed an immediate improvement in performance.
    "The turbo kicked in right away," Treaster said.  "There was no lag in
response time.  Now I have more power on grades."
    Owing to its unique design, the Liberator dramatically reduces back
pressure, enhancing engine performance especially in trucks that are four or
more years old.  Dynamometer tests show that the Liberator increases
horsepower by 5 hp to 15 hp.
    In addition to more power and no turbo lag, Treaster said he noticed a
difference in the smoke.  Before installing the Liberator, his 1994 Ford would
belch black smoke for the full 10 minutes that he warmed it up before
beginning his daily route.
    "With the Liberator, there was a quick puff of black, then gray, then
white, then nothing.  Hey where did the smoke go?" Treaster said.
    AET Chief Operating Officer Bob de Kruyff commented that the absence of
black smoke is an indication that fewer particulates are being emitted into
the atmosphere.
    Offered exclusively by AET, Liberator is made of stainless steel and comes
with a lifetime guarantee to original owners.  Purchasers who pay cash, check
or credit card are eligible for a 30-day money back guarantee.  Lease terms
are available for fleets or independent owner/operators.
