  • 5 Inch Tip Diameter
  • Gas

    • Stainless steel wool layer insulates perforated core to absorb noise, shield against high exhaust temperatures, and prevent blowouts
    • No baffles, chambers, or louvers that restrict airflow
  • Boasts MagnaFlow's signature sound, which is deep and throaty on the throttle but quiet inside your vehicle
  • Made of 100-percent stainless steel to resist corrosion
  • Includes 2 tips, as well as clamps and hangers for installation
  • Custom fit for your vehicle
  • Made in the USA

  • 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. 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 in order to boost power.


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 muffler in this system increase horsepower, torque, and fuel efficiency.


MagnaFlow's signature sound is deep and throaty on the throttle while remaining quiet inside your vehicle.


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

Your service was outstanding. The Magnaflow works great, but I sold my jeep and I will start with a new project.
