FAQs About 2019-Present Silverado 5.3L V8 Exhaust Upgrades
What years and configurations does this exhaust fit?
This system is designed for the 2019 and newer Chevy Silverado 1500 equipped with the 5.3L V8 engine, Extended Cab, 4WD, and the 6.5-foot standard bed. It does not fit the 2019 Silverado 1500 LD model, which uses an older body style and is covered under a separate MRT part number.
What does the MRT Deep and Mellow Cat-Back sound like on the fourth-gen Silverado?
At steady-state driving, you get a subtle, pleasing hum that is present without being overbearing. At idle and on engine revs, the exhaust note is clearly audible and engaging, and getting on the throttle opens the system up into a deeper, more spirited performance sound. It is a great daily driver tone that rewards you every time you accelerate without demanding attention when you do not want it.
Is there a drone or resonance with this system at highway speed?
MRT rates the drone at a 1 out of 10, making this one of the most comfortable systems in the MRT Silverado lineup for daily driving and long highway trips. The exhaust increases the sound level versus stock without causing the low-frequency cabin resonance that makes many performance exhaust systems unpleasant to live with.
Will this exhaust improve horsepower, torque, and fuel economy on my 2019+ Silverado?
Yes. The larger 3-inch tube diameter and straight-through muffler design reduce back pressure and improve exhaust airflow significantly compared to the factory system. The result is a noticeable uplift in horsepower, torque, and fuel economy that owners report feeling on the first drive.
Do I need a tune after installing this cat-back on my fourth-gen Silverado?
No tune is required. This is a direct bolt-on replacement that is fully compatible with the factory ECU on the supported 2019 and newer Silverado 1500 5.3L V8 configuration without any additional programming or calibration.
How long does installation take, and what tools do I need?
Installation takes approximately 90 minutes using only common hand tools. The system is designed for a straightforward DIY install in a driveway or backyard without a lift or specialty equipment, making it one of the most accessible upgrades you can do on your Silverado.
What tip finish options are available?
Two finishes are offered: a polished T304 stainless steel single tip for a clean, premium look, and a Black Ops matte ceramic finish for a stealthy, blacked-out appearance at an additional cost.
How does this compare to the MRT Tough Truck Cat-Back (92T106) for the same years?
The Deep and Mellow Cat-Back is quieter and more refined than the Tough Truck Cat-Back, which carries a loudness rating of 9 out of 10 and delivers an exhaust presence that is always on at every RPM. Choose the Deep and Mellow if you want a noticeable upgrade from stock that stays composed and comfortable during everyday driving. Choose the Tough Truck if you want the loudest, most aggressive MRT sound available for the 2019 and newer Silverado 1500 5.3L V8.
Does this system also fit the 2019+ GMC Sierra 1500?
Yes. MRT offers a version of this same system specifically fitment-tested for the 2019 and newer GMC Sierra 1500 5.3L V8 under part number 92T111G. Visit shopmrt.com or call MRT for details.

This system ships with MRT's Limited Lifetime Warranty. Full warranty terms are available on the warranty page at shopmrt.com. For questions or to schedule a professional installation near Plymouth, Michigan, call MRT at (734) 455-5807.
