MagnaFlow 15659 Street Series Stainless Cat-Back Performance Exhaust System

The MagnaFlow 15659 Street Series Cat-Back Performance Exhaust System is a direct-fit, stainless steel exhaust upgrade engineered to deliver the deep, resonant tone and dyno-proven power gains MagnaFlow is known for. This cat-back system replaces all stock exhaust components from the catalytic converter rearward, improving exhaust flow dynamics and overall engine performance.

Featuring mandrel-bent 3-inch main piping and a straight-through muffler design, the 15659 routes to a single passenger-side rear exit finished with a polished 3.5-inch welded-on single-wall angle-cut tip. Sound levels are tuned for a moderate exterior tone and a mild interior volume — aggressive enough to turn heads without being intrusive on daily drives.
