Magnaflow 15145 Street Series Stainless Cat-Back Performance Exhaust System

The Magnaflow 15145 Street Series Stainless Cat-Back Exhaust System delivers the signature resonant, throaty exhaust tone Magnaflow is known for, backed by dyno-proven performance gains. Engineered to replace all factory exhaust components from the catalytic converter rearward, this cat-back system is a direct-fit upgrade designed for straightforward DIY installation.

Built from durable, corrosion-resistant stainless steel and manufactured using CNC precision robotic techniques, the 15145 features fast-flowing, mandrel bent 2.5-inch main piping paired with a straight-through muffler for improved exhaust gas evacuation and reduced back pressure. The system exits through a single passenger-side rear outlet tipped with a 4-inch polished, double-wall, angle-cut rolled-edge tip for an aggressive, finished appearance.
