Increased exhaust system backpressure adversely affects performance and fuel economy. Based on system testing, (not just testing of the muffler) the Mega-Flow™ RV muffler's straight-through, three chamber design offers as much as 30% reduction in back-pressure while maintaining an excellent acoustic reading of 69.5 Db(A). This combination is superior to any competitive model based on published test data, and confirmed in our state-of-the-art engineering facility.
Specifically designed for recreational vehicles, the Mega-Flow™ RV muffler is built by the world's largest supplier of exhaust systems and components. Tenneco has been the leader in nearly every major advance in vehicle exhaust for more than 70 years. Mega-Flow™ RV mufflers combine top quality materials and engineering with cutting edge technology to deliver unparalled performance. The Mega-Flow™ RV muffler is capable of flowing twice the exhaust gas flowed by original equipment systems. Unique proprietary glass technology allows freer airflow throughout the systems while maintaining sound control.
