Heavy-duty muffler designed for fuel efficiency

Tenneco says its Walker Mega-Flow muffler utilizes an open-style design with high-strength OCF roving, which improves fuel efficiency without impacting acoustics. Specifically designed for Class 7 and 8 trucks, the Mega-Flow muffler uses ultra-high-flow technology engineered to reduce system back-pressure by as much as 30 percent.

According to Tenneco, vehicles equipped with Mega-Flow mufflers achieve an average fuel efficiency improvement of .24 miles per gallon, or 4 percent, over original equipment mufflers. The Mega-Flow muffler also features re-metallized welds designed to provide enhanced strength and corrosion resistance for a full range of heavy-duty applications.
