Magnaflow Logo

The MagnaFlow Chevrolet Tahoe/GMC Yukon Street Series Cat-Back Performance Exhaust System #19540 is the perfect choice if you want your 2021 Chevrolet Tahoe (Z71/RST/LT/LS) or GMC Yukon to sound and perform as great as it looks while keeping interior noise to a minimum.

Deep Magnaflow Performance Sound:

  • Exterior Sound: Moderate
  • Interior Sound: Mild

Noise control is possible thanks to MagnaFlow’s No Drone Technology (NDT), which utilizes quarter-wave passive noise cancellation tuned to the specific droning frequency of your Chevrolet Tahoe or GMC Yukon to eliminate droning. NDT was designed to take the most popular bolt-on modifications into consideration.

This cat-back exhaust kit will inject your 2021 Chevrolet Tahoe (Z71/RST/LT/LS) or GMC Yukon with MagnaFlow’s deep signature exhaust tone and dyno proven performance thanks to its 3” diameter main piping, straight-through muffler, quarter-wave resonator, 4” black chromed tip and single passenger side rear exit layout.

The entire exhaust kit is made of stainless steel and designed with mild interior noise levels, weight and ground clearance in mind for optimal durability and utility. CNC precision manufacturing and mandrel bent tubing guarantee a perfect fit, allowing the whole exhaust system to bolt on easily for installation.
