MagnaFlow 19237 Street Series Stainless Cat-Back Performance Exhaust System

The MagnaFlow 19237 Street Series Cat-Back Performance Exhaust System delivers the signature resonant, throaty exhaust note MagnaFlow is known for, backed by dyno-proven performance gains. This complete cat-back exhaust system replaces all stock exhaust components from just behind the catalytic converter rearward, providing a noticeable upgrade in both sound and power.

Built around mandrel-bent 2.5-inch main piping, the system uses a free-flowing, straight-through muffler design to maximize exhaust gas evacuation and improve engine efficiency. The system exits through a quad split rear configuration finished with polished, welded-on double wall angle-cut folded edge tips for a premium appearance. Sound levels are tuned for a moderate exterior tone with a mild interior character — sporty and engaging without being intrusive on long drives.
