Designed for 2007.5–2025 Silverado and Sierra 2500HD/3500HD trucks with the 6.6L Duramax, this system brings out that deep, powerful tone diesel owners love—without touching emissions components. The first thing you’ll notice is the sound. It’s not obnoxious or over the top, but it’s bold, throaty, and unmistakably diesel. MagnaFlow tuned this system to enhance your truck’s natural exhaust note, so every start-up, gear change, and throttle input feels a little more alive. What's more, the 5-inch diameter improves exhaust flow compared to the stock system, helping reduce backpressure and supporting performance gains, especially on tuned or heavily worked trucks. At the tail end, the system features a black intercooled tip. High-Quality Construction with Bolt-On Install From a construction standpoint, it’s built to last. The entire system is made from durable stainless steel and finished in a high-temp black powder coat that resists corrosion and adds a stealthy, aggressive look. That finish doesn’t just look good—it also helps manage heat and protect the system in harsh conditions, whether you're towing, working, or hitting the trails. Best of all, installation is straightforward thanks to MagnaFlow’s use of 3D scanning to ensure perfect fitment. This system bolts directly to your factory DPF flange and includes all the hardware you’ll need for a clean, do-it-yourself install. There’s no cutting or welding, and everything lines up with OEM mounting points for a hassle-free experience in the garage or driveway.
