Product Details
If you're looking to get more out of your 2000-2003 Ford F250 or F350 with the 7.3L Power Stroke engine, this 4-inch turbo-back dual exhaust system from Diamond Eye Performance is a solid choice. This kit replaces your entire factory exhaust system from the turbocharger all the way back, including the muffler and tailpipes, and is designed to improve exhaust flow. It also comes with a pyrometer plug, which is handy if you plan on installing a pyrometer to monitor your exhaust gas temperatures.
This system is constructed from durable aluminized steel, which offers good resistance to corrosion and is a well-built option for a truck that works hard. By increasing the diameter from the stock 3-inch piping to a full 4 inches, this kit allows your 7.3L Power Stroke to breathe much more freely. This improved flow can lead to a noticeable difference in how the engine performs, especially under load, and it often results in a deeper, more aggressive exhaust tone that many truck owners prefer. The dual outlet design also gives your truck a more commanding presence.
When installing this kit, you'll be removing the factory muffler and replacing it with a straight-through design that's part of the turbo-back system. This means you'll get a more direct path for exhaust gases. Keep in mind that this system is not CARB approved and cannot be shipped to California. For installation, you'll typically be bolting this system up to the factory turbo outlet and working your way back, often requiring basic hand tools. Refer to the manufacturer's installation instructions for specific details.
