Magnaflow 15555 Street Series Stainless Axle-Back Performance Exhaust System

The MagnaFlow 15555 Street Series Stainless Axle-Back Exhaust System delivers dyno-proven performance gains and MagnaFlow's signature deep, resonant exhaust tone. Engineered as a direct bolt-on replacement, this system covers the axle-back section of the exhaust — from near the rear axle rearward — for a straightforward upgrade without cutting or fabrication.

Built from durable, corrosion-resistant stainless steel using CNC precision robotic manufacturing techniques, this system is designed for lasting reliability. Mandrel-bent 2.25-inch main piping ensures unrestricted exhaust flow, while the straight-through muffler design minimizes backpressure for improved power and efficiency.
