Product Details

AP Exhaust 38718 is an exhaust pipe designed around the factory routing used on select Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD trucks, along with Silverado 3500 HD and Sierra 3500 HD applications listed below. The aluminized steel construction supports replacement of the factory pipe section while maintaining the original exhaust path. This part cross-references GM OE number 25811684 for the same application.

For trucks with welded factory exhaust assemblies, this helps simplify service by matching the original pipe shape and fit requirements. If you are sourcing AP Exhaust 38718 for a Silverado 2500 HD or Sierra 2500 HD exhaust repair, confirm the exact model year and wheelbase before installation.
