This cat-back exhaust system improves engine performance and durability by boosting horsepower and torque. Its technologically advanced, Mandrel bent tubing and straight-through muffler allow the exhaust to flow more freely through the system.


Features:

  • Improves engine performance by increasing horsepower, torque and fuel efficiency and decreasing exhaust gas temperature
  • Mandrel bent tubes allow for unrestricted airflow by maintaining the same diameter through every curve
    • Unrestricted airflow decreases back pressure ("exhaust turbulence")
  • Straight-through muffler has a stainless steel perforated core that runs straight through, end to end
    • Layer of stainless steel wool insulates the perforated core to absorb noise, shield high exhaust temperatures and prevent blowouts
    • Contains no baffles, chambers or louvers that restrict airflow
  • Signature sound is deep and throaty on throttle but quiet inside the vehicle
  • All materials made with 100% stainless steel
  • Clamps and hangers included for installation
  • Lifetime warranty


Specs:

  • Tubing diameter: 2-1/2"
  • Muffler dimensions: 4" round x 14" long
  • Tailpipe diameter: 2-1/2"
  • Tip diameter: 3-1/2"
  • Number of tips included: 2
  • Dual exhaust system
  • Split rear exit position


The cat-back system is the portion of the exhaust system from the outlet of the catalytic converter back to the tailpipe. The Competition Series is designed for American-made vehicles and boasts a noticeably more aggressive tone than other MagnaFlow exhaust systems, so it's perfect for a day at the track. 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, which then increases horsepower and torque.


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


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.

The glass pack mufflers are legal for use, as long as your system is within the local sound ordinance. You will need to check local laws to be sure. If you would like a bolt on system and your Mustang has the V8, 4.6L engine, there are two...
