Construction & Design

Crafted from premium stainless steel, the MagnaFlow Street Series exhaust system offers excellent resistance to rust and corrosion, essential for off-road durability and all-weather use. The mandrel-bent tubing maintains a smooth internal diameter through bends, preventing flow restrictions and preserving horsepower and torque gains.

Each component is precision-cut and welded using robotic CNC technology, ensuring consistent weld quality and a perfect fit every time. The polished double wall tips not only enhance the visual appeal but also protect the edges from damage and corrosion, maintaining a showroom finish over time.
