Internal muffler diagram of straight-through, perforated core, mesh and acoustic fiber

A. This muffler's stainless steel, perforated core runs straight through from the inlet to the outlet, allowing the exhaust to pass through without restriction. It contains no baffles, chambers or louvers that would restrict airflow. When air flows unimpeded through the exhaust system, horsepower, torque and fuel efficiency increase. All these factors lead to improved engine performance.

B. and C. To regulate loud exhaust noise, tightly packed layers of stainless steel mesh (B) and acoustic fiber (C) insulate the core. These materials absorb sound waves, shield high temperatures and prevent hazardous blowouts. The resulting tone is a smooth, deep growl, specific to MagnaFlow.

D. The inlets and outlets are lap-joint welded to the muffler body for durable construction that eliminates distortion and cracking.

E. All materials are made from 100-percent stainless steel with a satin finish, making this muffler corrosion resistant.

  • 03 Chevy S10 with LSA 6.2 engine
    I reached out to my contact at MagnaFlow to get their take on this. The muffler is the tricky part because it's going to come down to space. A good place to start is the MagnaFlow # MF12279 which measures 5 x 8 x 30 inches. Another option is # MF12579 which is 5 x 11 x 28 inches. Both will fit your 3 inch pipes. For a 4 inch resonator # MF14419, which is technically a muffler but for your truck will be acting as the resonator. Another option if you want to go to a 5 inch is # MF12867....

This will not be a good option for the 2-1/2 inch pipe on your Ford F-150/ For the 2-1/2 inch pipe on your 2007 F-150, I instead recommend the MagnaFlow Straight-Through Muffler # MF12866.
