Magnaflow Mufflers are the straight Wide Open performance mufflers with smooth deep tones. First and foremost Magnaflow mufflers are developed to be a superior product line of performance mufflers. Wide Open performance Magnaflow mufflers outflow OEM chamber style mufflers by as much as 16%. This reduces engine heat and back pressure and improves exhaust scavenging from the combustion chamber. Magnaflow mufflers minimizes the power robbing effects of the OEM system to restore torque and horsepower to the engine.

From aluminized steel, to polished stainless steel, there probably are MagnaFlow mufflers or MagnaFlow cat back systems to suit your desire.
