  1. MagnaFlow converters have a ribbed body that minimizes expansion and distortion when the converter heats up.
  2. MagnaFlow converters have a 1/2” lap-joint where the necks meet the body. The neck does not extend into the converter body where it could hamper exhaust flow.
  3. We maintain separate dies on different sized inlets. We don’t skimp by putting larger neck sizes on smaller bodies. This would reduce the flow of the converter and reduce the quality of our product.
  4. MagnaFlow uses a monolithic honeycomb catalyst. The ceramic is designed for maximum flow and surface area. The coating method is strictly controlled to maintain exact specifications. (49-State & Canada emissions only)
  5. MagnaFlow uses a heavier gauge stainless steel, tip to tip.
  6. MagnaFlow converters are seam welded close to the converter body for a strong, tight bond.
  7. MagnaFlow installs a factory capped, 90 degree air tube on “with air” converters. This saves time during installation. There is no need for additional labor to weld on an air tube or to create a bend when only an air tube stub is provided.
  8. MagnaFlow uses an aluminized or stainless OEM-style ribbed heat shield that creates a rigid wall of protection against heat and adds to the structural stability of the converter.
