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

The cat-back system is the portion of the exhaust system from the outlet of the catalytic converter to the tailpipe. MagnaFlow systems have Mandrel bent tubes that allow for unrestricted airflow by maintaining the same diameter throughout every curve. This curvature leads to decreased back pressure.
MagnaFlow mufflers have a stainless steel perforated core that runs straight 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 high exhaust temperatures and prevent blowouts.
Together, the Mandrel bent tubes and straight-through muffler increase horsepower, torque and fuel efficiency and decrease exhaust gas temperature. MagnaFlow's signature sound is deep and throaty on throttle but quiet inside vehicles. All materials are made with 100 percent stainless steel. Clamps and hangers are included for installation. It includes a lifetime warranty.

This dyno chart displays the differences in power and torque between OEM (blue) and MagnaFlow (red) exhaust systems. The darker red and blue lines represent the torque measurements; the lighter red and blue lines represent the power measurements.
