MagnaFlow 2021 GM Yukon/Tahoe V8 5.3L Street Series Cat-Back Exhaust

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

Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.
