MagnaFlow Exhaust Systems - MF15132

This cat-back exhaust system has technologically advanced, mandrel-bent tubing and 4 performance mufflers, which allow exhaust to flow freely through the system. This improves engine performance, boosting horsepower and torque.


  • Improves engine performance thereby increasing horsepower, torque, and fuel efficiency
    • Mandrel-bent tubes allow for unrestricted airflow by maintaining the same diameter through every curve
      • Unrestricted airflow decreases back pressure ("exhaust turbulence")
  • Each performance muffler has a stainless steel, perforated core that runs straight through, end to end, with a slight bend to reach the offset outlet
    • Stainless steel wool layer insulates each perforated core to absorb noise, shield against high exhaust temperatures, and prevent blowouts
    • No baffles, chambers, or louvers that restrict airflow
  • Delivers a smooth, deep tone similar to that of exhaust sytems that have MagnaFlow's straight-through mufflers
  • Made of 100-percent stainless steel to resist corrosion
  • Includes 2 dual, square tips, as well as clamps and hangers for installation
  • Custom fit for your vehicle
  • Made in the USA


  • Tubing diameter: 2-1/4" and 2-1/2"
  • Front muffler dimensions: 4" tall x 9" wide x 18" long
  • Rear muffler dimensions: 4" tall x 9" wide x 11" long
  • Number of tips included: 2
  • Exhaust system: dual
  • Exit position: dual split rear
  • Lifetime warranty

The cat-back system is the portion of the exhaust system from the outlet of the catalytic converter back to the tailpipe. The Street Series is designed for domestic American vehicles and has a slightly less aggressive sound than other MagnaFlow domestic exhaust systems, so it's more appropriate for street use. MagnaFlow systems boast mandrel-bent tubes that allow for unrestricted airflow by maintaining the same diameter through every curve. This consistency in diameter decreases back pressure.

Each MagnaFlow performance muffler has a stainless steel, perforated core that runs through it - end to end - with no baffles, chambers, or louvers that restrict airflow. A stainless steel wool layer insulates the perforated core to absorb noise, shield against high exhaust temperatures, and prevent blowouts. Together, the mandrel-bent tubes and mufflers in this system increase horsepower, torque, and fuel efficiency. MagnaFlow's signature sound is deep and throaty on the throttle but quiet inside your vehicle.

All system components are made with 100-percent stainless steel. Clamps and hangers are included for installing onto the OEM exhaust system. MagnaFlow provides a lifetime warranty.

Do you have a question about this Exhaust System?

  • Will the Magnaflow Cat-Back part # MF15123 Cause Issues with the MDS Of a 2013 Dodge Challenger
  • I think the dealer you are dealing with is trying to get out of fixing the real problem of your car. The MDS or fuel saver mode on your car is not based on back pressure or the EGR valve, it is based on engine load, throttle position and speed. From the research I've done the MDS systems on these cars is kind of notorious for behaving strangely. Also, there are a ton of other Challenger owners out there with aftermarket cat-back systems that did not cause any problems with the MDS system...
