FAQs for 2007-2018 Silverado 1500 Exhaust Upgrade
What years and engines does this exhaust fit?
This system fits the 2007 through 2018 Chevrolet Silverado 1500 equipped with the 5.3L V8 engine. It does not fit other Silverado 1500 engine configurations from those years, including the 4.3L V6, 4.8L V8, or 6.2L V8. Note that this system also fits the 2019 Silverado 1500 LD model, but does not fit the 2019 new body style Silverado.
What does the MRT Tough Truck Cat-Back sound like on the Silverado 5.3L V8?
It delivers a loud, deep muscle car sound with an exhaust presence that is always on. At idle, you get a confident, aggressive rumble. Under acceleration, you can hear the gear changes clearly, and wide-open throttle brings a livelier, deeper growl with more exhaust bite. On deceleration, there are satisfying burbles that remind you this is no longer a stock system.
Is there a drone or resonance with this system at highway speed?
MRT rates the drone at a 1 out of 10 despite the loudness rating of 9 out of 10. The system is engineered to be loud and present without creating the uncomfortable low-frequency cabin resonance that ruins long drives. Most owners find highway cruising remains enjoyable.
Will this exhaust improve horsepower, torque, and fuel economy?
Yes. The straight-through resonator design and 3-inch mandrel-bent tubing dramatically reduce exhaust back pressure and improve flow. The result is a noticeable increase in horsepower, torque, and fuel efficiency that owners report feeling immediately from the first drive.
Do I need a tune after installing this cat-back on my Silverado?
No tune is required. This is a direct bolt-on replacement that is fully compatible with the factory ECU on all supported 2007 through 2018 Silverado 1500 5.3L V8 configurations 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, making it one of the most accessible performance 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 Deep and Mellow Cat-Back (92T110) for the same years?
The Tough Truck Cat-Back is significantly louder than the Deep and Mellow, carrying a loudness rating of 9 out of 10 compared to 5 out of 10 for the Deep and Mellow. The Tough Truck exhaust presence is always on at every RPM, while the Deep and Mellow is more of an on-demand sound that stays quieter during relaxed driving. Choose the Tough Truck if you want the loudest, most aggressive MRT sound available for the 2007 through 2018 Silverado 1500 5.3L V8.
Does this system also fit the GMC Sierra 1500?
Yes. MRT offers a version of this same system specifically fitment-tested for the 2007 through 2018 GMC Sierra 1500 5.3L V8 under part number 92T105G.

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.
