These dual exhaust systems flow up to 50% better than your stock exhaust and provide a noticable increase in power and throttle response. Each system comes with pre-installed hangers and can be installed on your vehicle in your driveway in about 45 minutes using common tools. So upgrade your GMC Sierra and unleash the mighty Duramax diesel with this high flowing exhaust system from Magnaflow.

Open up the performance potential of your Duramax Diesel with a Magnaflow performance exhaust system. Utilizing mandrel-bent, 4" stainless steel tubing, a Magnaflow exhaust will not only add horsepower and torque but will last a lifetime, too. Magnaflow offers you a choice of applications to suit any style or budget. Choose from the following options:

Magnaflow Performance diesel systems is a premium line that includes mandrel-bent stainless steel tubing, a 100% stainless steel mirror-finish muffler, 4" band clamps, and a polished single-wall intercooled tip.

Magnaflow XL Performance is a mid-level performance line that includes mandrel-bent stainless steel tubing, a 100% stainless steel satin-finish muffler, 4" saddle clamps, and a 5" polished single-wall intercooled tip.

Magnaflow Pro Performance is an entry-level performance line which includes mandrel-bent stainless steel tubing, muffler-delete pipe, and 4" saddle clamps.

All options feature the Magnaflow "Wide Open" Performance Difference:

All Stainless Steel Construction:

The Magnaflow muffler is encased in an all stainless steel body and features stainless steel end caps and 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 filters out the harsh exhaust vibrations, producing Magnaflow`s rich, powerful performance tone. This tone offers a deep bass 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, allowing sound vibrations to pass freely into the acoustical-absorbing material inside yet preventing 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. No Restrictions:

Magnaflow’s 1-pc, 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.
