Construction & Design:

Magnaflow’s catalytic converter features a spun body design that closely replicates the original equipment manufacturer’s (OEM) flow dynamics, ensuring your vehicle maintains factory-level performance and fuel efficiency. The use of mandrel-bent tubing preserves the smooth exhaust path, reducing turbulence and backpressure. Constructed from high-strength 16 gauge 409 stainless steel, this converter resists corrosion and withstands harsh operating conditions for maximum durability.

The single laser fusion weld on the spun body minimizes the risk of exhaust leaks, while the compact, low-mass design enhances thermal efficiency, helping the converter reach optimal operating temperatures quickly. Durable 308 stainless steel MIG welds further reinforce the assembly, ensuring long-lasting reliability.
