Exhaust Components for 2017-2019 6.6L L5P Duramax

A well-functioning exhaust system is closely linked to engine performance: this is true for all engines. And like any engine, the 2017-2019 6.6L L5P Duramax can suffer from several exhaust-related issues. Malfunctioning sensors, broken components, or dirty filters can impact performance and compromise your diesel engine’s trademark reliability and power.

Diesel engines, like your L5P Duramax, come equipped with unique exhaust parts, including the diesel particulate filter (DPF). This is an emissions-control part that reduces pollutants by trapping exhaust soot; as you can imagine, this part can get dirty fast. When your DPF gets clogged, you might experience a loss of power, poorer fuel economy, and notice black smoke coming from your exhaust pipe. At ProSource Diesel, we offer ways to keep tabs on your DPF. You can clean a clogged DPF using a probe kit or specialized cleaning products.

We also offer exhaust upgrades that get you even more out of an already-reliable engine. Aftermarket exhaust pipes can improve engine performance further by reducing exhaust back pressure and improving airflow over your stock L5P Duramax pipes. This could provide faster turbo response and lower exhaust temperatures.
