Advanced Exhaust Technologies' New Liberator Muffler Boosts Power in Older TrucksAUBURN 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.
