What is a turbo back exhaust system?

A turbo back exhaust system replaces all the exhaust components from the outlet of your turbocharger all the way to the tailpipe. This means it includes the downpipe, mid-pipe, muffler, and tailpipe, offering a complete upgrade for improved flow.

Why choose stainless steel for an exhaust system?

Stainless steel is chosen for exhaust systems because it's highly resistant to rust and corrosion, especially compared to aluminized steel or mild steel. This means your exhaust system will last much longer, even in harsh weather conditions.

Is this exhaust system legal in all states?

This particular exhaust system is not CARB approved and cannot be shipped to California due to emissions regulations. Always check your local regulations regarding exhaust system modifications.

Product Details

Diamond Eye Performance is known for its modern manufacturing approach, utilizing CNC mandrel bending machines to create high-quality exhaust components. This turbo back exhaust system is specifically built for your 1989-1993 Dodge 5.9L Cummins 2500 or 3500 2-wheel drive truck, offering a substantial upgrade over the stock setup.

This kit features a 4-inch diameter stainless steel construction, which not only resists corrosion for long-term durability but also allows for significantly improved exhaust gas flow. Mandrel bending ensures consistent pipe diameter throughout the bends, which helps maintain exhaust velocity and can lead to a more responsive feel. The system includes a single muffler and is designed as a complete turbo back replacement, meaning it replaces everything from the turbocharger outlet all the way to the rear of the vehicle.

When installing this system, you can expect a direct fit installation, as it's designed to bolt up to your existing turbocharger and frame. While this system is not CARB approved and cannot be shipped to California, it's a solid option for Cummins owners looking to enhance their truck's performance and sound. You'll want to check manufacturer fitment data to confirm compatibility with your specific D250 or D350 model.
