Whether you’re looking for the best replacement emission system, muffler, piping or accessories, AP Emissions has the aftermarket parts you need to keep your fleet or heavy-duty vehicle performing at its peak day after day.

We offer industry-leading diesel particulate filters (DPF) and diesel oxidation catalyst (DOC) units that are built to fit and manufactured for quality and durability that extends vehicle service life. That means less time in the shop, more time on the road. AP Emissions has developed processes that enable us to engineer performance and reliability into every product we bring to market.

Our replacement diesel exhaust and emission products comply with all applicable U.S. EPA, U.S. Forestry Department and U.S. Agricultural Department requirements – providing equivalent or improved emissions control performance versus OEM units when properly installed in diesel equipment.*

That is one reason why we are the go-to provider for technicians who keep heavy duty trucks rolling and delivery vehicles at your doorstep.

*Certain emission control parts are not legal for sale or use in California or areas requiring compliance with California emissions regulations. Ask your DuraFit or DieselTech dealer for more details or contact us.
