Product Description

The MagnaFlow 19580 Street Series Cat-Back Exhaust System is purpose-engineered for the 2021-2024 Chevrolet Tahoe and GMC Yukon equipped with the 6.2L V8 engine, as well as 2021-2023 Cadillac Escalade 6.2L V8 models. The standout technology in this system is MagnaFlow's No Drone Technology (NDT) - a passive quarter-wave resonator system tuned to the specific exhaust drone frequency produced by the 6.2L V8 in these large SUVs. The result is a system that delivers the deep, aggressive MagnaFlow exhaust tone you want on the outside, while maintaining a comfortable, drone-free cabin experience - even at highway cruise speeds. NDT tuning was specifically developed with popular bolt-on upgrades in mind, so the drone cancellation remains effective after typical modifications.

The system routes 3-inch mandrel-bent 409 stainless steel piping from the factory catalytic converter to a quad split rear exit, terminating in four 4-inch black chrome double-wall angle-cut tips for a bold, aggressive appearance. The straight-through muffler design removes the restrictive baffling of the factory unit, improving exhaust flow and producing dyno-proven gains in horsepower and torque. The exhaust routing was designed with ground clearance and the utility of the full-size SUV platform in mind, ensuring departure angles and off-road capability are not compromised.

Installation is a direct bolt-on using OEM mounting locations, made possible by MagnaFlow's use of 3D scanning technology during development. All hardware, clamps, and hangers are included, and the removable black chrome tips add an extra layer of customization flexibility. Note that this system fits 6.2L V8 models only - the 5.3L Tahoe, Yukon, and Escalade, as well as the Suburban, Yukon XL, and Escalade ESV, require different part numbers. Made in the USA and backed by MagnaFlow's limited lifetime structural warranty, with a 1-year finish warranty covering the black chrome tip coating.
