MagnaFlow Performance mufflers are 100% polished stainless steel and lap-joint welded for solid construction and rugged reliability even in the most extreme conditions.
They feature a free-flowing, straight-through perforated stainless steel core, stainless mesh wrap and acoustical fiber fill to deliver that smooth, deep tone. Mufflers are packed tight with this acoustical material unlike some others' products to ensure long life and no sound degradation over time. Backed by a Lifetime Warranty.
Backpressure is a typical feature of an exhaust system. The backpressure on the exhaust flow can help to reduce sound, but at the same time, it limits engine power. This power reduction comes from an inefficient burn in the combustion chamber where spent exhaust gasses are backed-up into the combustion chamber and contaminate the next burn cycle.
A second problem associated with backpressure is heat build-up. This occours in the OEM style chamber muffler. Hot exhaust gasses are forced through louvers and into dead-end chambers. The heat builds up in the muffler and then backs itself up through the entire exhaust system to the exhaust manifold and engine. This heat retention causes damage to the muffler as well as the catalytic converter, the system tubing, the manifold and gaskets. Even ignition wires can burn up due to an overheated, inefficient exhaust system.
MagnaFlow reduces the backpresure while maintaining a rich powerful performance tone. Annoying exhaust frequencies are dampened with a dense wall of acoustical absorbing material.
The straight-through design prevents excessive heat retention allowing the entire system to run cooler and last longer. MagnaFlow overcomes the backpressure problem and releases more torque and more horsepower from your engine.
