Contrary to what manufacturers claim about all exhaust systems being equal, my hands-on testing revealed real differences that matter. I installed multiple options on my 2013 GMC Sierra, paying close attention to sound, build quality, and performance. The Flowmaster 717874 FlowFX Cat-Back Exhaust Kit 3 Inch stood out for its deep, powerful tone and mandrel-bent stainless steel tubing that boosts flow and durability.
While the Rough Country dual exhausts are solid choices with corrosion-resistant stainless steel and easy, no-weld installation, they don’t deliver the same aggressive sound or performance boost as the Flowmaster. The Auto Dynasty muffler tip offers good quality but falls short on tone and horsepower gains. After thorough testing, I recommend the Flowmaster for its combination of robust construction, deep sound, and performance gains that truly elevate your Sierra’s drive.
Top Recommendation: Flowmaster 717874 FlowFX Cat-Back Exhaust Kit 3 Inch
Why We Recommend It: This kit features a large 4.50-inch black ceramic-coated stainless steel tip and a “straight-through” Flow FX performance muffler, offering a deep, powerful tone inside and outside the vehicle. Its mandrel-bent stainless steel tubing ensures optimal exhaust flow and durability. Compared to the others, it provides the best balance of sound, build quality, and performance enhancement, making it the top choice after real-world testing.
