All Stainless Steel or Aluminized Steel
The MagnaFlow muffler is encased in an all stainless steel or aluminized body as well as end caps and stainless steel perforated core. These steels reflect heat and resist corrosion better than cold-rolled steel. They also retain their finish longer, adding to MagnaFlow`s long life and clean appearance.

Straight-Through. No Restrictions
MagnaFlow’s one piece perforated stainless steel core lets exhaust gasses fly right through. Nothing gets in the way to slow them down. You won’t find any pressed-in louvers causing turbulence here. No louvers. No baffles. No sharp turns. MagnaFlow’s straight-through design improves exhaust flow to increase torque and horsepower.

All Welded Lap-Joint Construction
Lap-Jointing is the 1/2" overlapped metal-to-metal construction technique used on all MagnaFlow mufflers. This 1/2" overlap of steel occurs at every joint, creating a stronger surface-to-surface bond than mufflers employing only a rolled edge joint. The lap-joint is completed using a smooth, continuous mig weld that seals the system and further strengthens the joint.

Stainless Steel Protective Mesh
The core is wrapped with stainless steel mesh that warms up quickly and maintains the muffler`s optimal temperature for exhaust movement. The mesh creates a porous barrier that allows sound vibrations to pass freely into the acoustical absorbing material inside yet prevents blowout and deterioration of the absorbing material.

High Temperature Acoustical Absorbing Material
Packed between the steel mesh and the steel shell is a high temperature acoustical absorbing material. This dense wall of fiber filters out the harsh exhaust vibrations producing MagnaFlow`s rich, powerful, performance tone.
