Installing an L5P downpipe on your 2017-2022 GM Duramax can be a game-changer for your truck's performance.

The L5P downpipe is designed to work seamlessly with the factory exhaust system, making installation relatively straightforward.

You'll need to purchase a high-flow catalytic converter and a downpipe specifically designed for the L5P engine.

The downpipe installation process typically takes around 4-6 hours, depending on your level of mechanical expertise.

Understanding and Choosing a Kit

L5P delete kits provide an opportunity for diesel engine enthusiasts to modify their vehicles, particularly the L5P Duramax.

These kits are designed to remove certain emissions control components, such as the Diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) system, to optimize engine performance and efficiency.

By eliminating restrictive components, the L5P delete kit can lead to increased airflow and reduced back pressure, which often translates to improved horsepower and torque.

L5P delete kits can reduce wear and tear on the engine, potentially leading to a longer lifespan.

Frequently Asked Questions

What does a downpipe do for a Duramax?

A Duramax downpipe reduces exhaust backpressure, allowing for faster turbo spool and lower exhaust gas temperatures, resulting in a more efficient and reliable engine. By installing a downpipe, you can unlock improved performance and longevity for your Duramax.

What happens when you install a downpipe?

Installing a downpipe directs exhaust gases more efficiently through your vehicle's exhaust system, potentially improving performance and reducing backpressure. This can be especially beneficial for vehicles with restrictive catalytic converters.

Where is the downpipe located?

The downpipe is typically located between the turbocharger and the center silencer in the exhaust system. It's usually situated after the turbocharger, connecting it to the rest of the exhaust system.
