4" DPF Filter-Back Exhaust System
The MagnaFlow Pro 4" filter-back exhaust offers the ultimate replacement for your stock system. It improves your vehicle's torque and horsepower while helping you to save on gas mileage. It is fully polished for a sleek shiny look.
Moderate Tone Muffler
The exhaust system gives a moderate and deep tone, thanks to its straight-through muffler. It has a perforated core that contains stainless steel wool to absorb noise and heat.
To prevent back pressure, the exhaust system tubing maintains a constant diameter. This mandrel tubing prevents back pressure and allows a smooth flow of exhaust gases which in turn allows the engine to work at an optimal speed. The result is improved performance, horsepower and torque.
