FlowMaster Exhaust Muffler for 2007-2014 GMC Yukon

The super 40 muffler was developed from our top ten race muffler lineup for use on the street and strip. Utilizing Delta Flow technology, this muffler gives the best performance to higher Horsepower vehicles. The super 40 features a black, 5 Inch X 10 Inch aluminized case, which keeps the resonance down while the deep outside tone says it’s a FlowMaster!.
35 years ago, FlowMaster ® mufflers were conceived as a solution to a growing problem with sound issues at race tracks in California and beyond. In his successful effort to quiet race cars without reducing performance, our founder refused to accept the status quo of the day and instead pushed exhaust technology beyond common thinking.
