MagnaFlow Chevy Colorado Cat-Back Dual Rear Exit Exhaust System 04-08

Stainless-Steel Construction:

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

High-Temperature, Acoustic-Absorbing Material:

Packed between the steel mesh and the steel shell is a high-temperature, acoustic-absorbing material. This dense wall of fiber filters out the harsh exhaust vibrations, producing MagnaFlow`s rich, powerful tone. This tone offers a deep bass sound when throttling, remaining quiet while idling and at highway speeds.

Stainless-Steel Protective Mesh:

The core is wrapped with a 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 acoustic-absorbing material inside, yet prevents blowout and deterioration of the absorbing material.

Welded Lap Joint Construction:

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 (metal inert gas) weld that seals the system and further strengthens the joint.

Straight-Through Exhaust Flow With No Restrictions:

MagnaFlow’s one-piece perforated stainless-steel core lets exhaust gasses fly right through. You won't find any pressed-in louvers, baffles, or sharp turns causing turbulence here. Nothing gets in the way to slow gasses down. MagnaFlow’s straight-through design improves exhaust flow to increase torque and horsepower.
