Let Your Truck Roar With Style And Purpose

If you’re looking to add serious attitude to your Super Duty while also making real performance gains, the aFe 49-43090-B Large Bore-HD exhaust system is the upgrade your truck deserves. This 5-inch DPF-back system isn’t just for show, though the massive black slash-cut tip and laser-cut aFe logo definitely turn heads, it’s also tuned to give your 6.7L Powerstroke a deeper, more aggressive exhaust note that’ll make every drive more exciting. Whether you’re towing, hauling, or just cruising down the highway, you’ll instantly notice the improved airflow and throttle response. Plus, the intercooled tip helps cool exhaust gases at the tailpipe, which can make a real difference under heavy loads or long drives. Installation is as easy as it gets thanks to a bolt-on design that uses factory mounting points, and only requires a small cut behind the DPF. And because it’s made with mandrel-bent 409 stainless steel and MIG-welded for strength, it’s built to last through years of abuse on the road or jobsite. This is a true performance exhaust system that blends form, function, and a whole lot of fun.

Engineered To Flow Strong And Last Long

Built for durability and engineered for performance, the aFe 49-43090-B is a carefully designed DPF-back system tailored for 2017-2025 Ford F250 and F350 Super Duty trucks equipped with the 6.7L Powerstroke diesel. The 5-inch mandrel-bent tubing allows for unrestricted airflow, reducing backpressure and increasing both horsepower and torque output. A mitered merge collector eliminates dead space inside the pipe, minimizing turbulence and maximizing exhaust flow efficiency. Every weld is hand MIG-welded for long-lasting structural integrity, even under intense vibration and extreme heat. The OE-style bayonet hangers ensure secure placement, holding up under tough conditions without rattling or sagging over time. This system also features intercooled vents at the tip to help reduce tailpipe temperatures, a small detail that adds to performance and longevity. Installation is straightforward, using your truck’s factory mounts with minimal cutting required behind the DPF unit. For drivers who demand technical quality and long-term value from their upgrades, this exhaust system delivers on every front.
