This custom-fit cat-back exhaust system has straight-through mufflers and mandrel-bent tubing that allow exhaust to flow freely through the system. This boosts horsepower and torque and helps to improve fuel efficiency for your GMC Sierra.


Features:

    • Unrestricted airflow decreases back pressure
  • Each straight-through muffler has a stainless steel, perforated core that runs directly from one end to the other
    • Stainless steel wool insulates each perforated core to absorb noise, shield from high exhaust temperatures, and prevent blowouts
    • No baffles, chambers, or louvers that restrict airflow
  • Moderate tone is smooth yet deep
  • 100-Percent 409 stainless steel construction is rustproof
  • Round, double-wall tip is made of polished stainless steel
  • Simple installation using factory mounting points
    • Clamps and hangers included

MagnaFlow Mandrel Bent Tubing

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 (or exhaust turbulence).


MagnaFlow Straight Through Perforated Core

Each MagnaFlow straight-through performance muffler has a stainless steel, perforated core that runs through the muffler - end to end - with no baffles, chambers, or louvers that restrict airflow. A layer of stainless steel wool insulates the perforated core to absorb noise, shield from 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 throttle while remaining quiet inside the vehicle. The MF Series produces a slightly less aggressive sound than other MagnaFlow systems, so it is more appropriate for street use.


All system components are made with 100-percent stainless steel. Clamps and hangers are included for installing onto your vehicle's factory mounting points.

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