Construction & Design

MagnaFlow’s Performance Header is expertly crafted from premium 16 gauge 409 stainless steel tubing, chosen for its excellent corrosion resistance and durability under high-heat conditions. The mandrel-bent tubing preserves the original equipment manufacturer’s geometry, ensuring smooth exhaust gas flow without restrictions that could hinder engine performance.

The header replicates the spun body catalytic converter design using advanced 3D scanning technology, guaranteeing a precise fit and function comparable to the original factory part. The single laser fusion weld technique enhances the header’s strength and reduces the risk of leaks, while also improving thermal efficiency to help the catalytic converter reach operating temperature faster.
