MagnaFlow Touring Series Cat-Back Performance Exhaust System 16533

The MagnaFlow Touring Series Cat-Back Performance Exhaust System 16533 is constructed from durable, corrosion-resistant stainless steel. It offers a powerful, resonant exhaust note and dyno-proven performance through improved exhaust gas flow. This system provides moderate exterior and mild interior sound levels. It features fast-flowing, mandrel-bent 2.5-inch main piping and two straight-through mufflers, terminating in a dual straight driver side rear exit with 3-inch polished, welded-on, double-wall, angle-cut, rolled-edge tips. This cat-back system replaces stock exhaust components from the catalytic converter back, includes flanges for bolt-on to stock manifolds, and features a 330-tuned front resonator. It is a direct-fit design, ensuring easy installation, manufactured using CNC precision robotic techniques in the USA, and backed by MagnaFlow's limited lifetime construction warranty. It is significantly lighter than the factory 330i exhaust.
