The Magnaflow Wide-Open Performance Difference

The Magnaflow muffler is encased in an all stainless steel with 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 to MagnaFlow`s long life and 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 does the job of filtering out the harsh exhaust vibrations, producing Magnaflow`s rich, powerful performance tone. This tone offers a deep base sound when throttling while remaining quiet during idle and highway speeds.

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 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—No Restrictions

Magnaflow’s one-piece perforated stainless steel core lets exhaust gases 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.
