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 polished finish, making this muffler corrosion resistant and giving it a mirror-like finish.

See what our Experts say about this MagnaFlow Performance Mufflers

  • What is Loudness Difference Between Magnaflow Mufflers MF12219 and MF14419
    The Magnaflow muffler part # MF12219 is going to be considerably quieter than the # MF14419. The 14419 is a straight through muffler that is only going to be just slightly quieter than a straight pipe with no muffler as the baffling is very thin around the cannister whereas the # MF12219 has quite a bit more insulation around it's core which will absorb a lot more sound. The 14419 is going to be very loud and some would say obnoxious, the 12219 on the other hand is going to be decently...

  • MagnaFlow Muffler and Resonator Recommendations for a 1996 Dodge Ram 2500 with V10 8.0 Liter
    I spoke with my contact at MagnaFlow and he recommended Muffler # MF12599 (if you are running 3 inch piping). He also stated that because of the size of the engine, you would also need to use a smaller, round muffler as a resonator, # MF14419 for 3 inch piping. If you are using different size piping, you would want to use a muffler that measures 5 x 11 x 22 with a resonator that measures 5 x 8 x 14.

  • 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....
