All Stainless Steel

The MagnaFlow muffler is encased in an all stainless steel body, as are the end caps and stainless steel perforated core. This steel reflects heat and resists corrosion better than cold-rolled steel. It also retains the finish longer, adding long life and a clean appearance.

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 a rich, powerful, performance tone.

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 it prevents blowout and deterioration of the absorbing material.

All Welded Lap-Joint Construction
The 1/2" overlapped, metal-to-metal construction is used on all 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.

Straight-Through Design, No Restrictions

The 1-pc, 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. The straight-through design improves exhaust flow to increase torque and horsepower.
