Dorman 674-5009 Turbocharger Down Pipe

Dorman 674-5009 is a stainless steel turbocharger down pipe built for exhaust service where durability and fit matter. The 3-inch outside diameter and 1.6 wall thickness support a robust exhaust path, while the natural stainless finish helps resist corrosion in demanding underhood conditions.

For technicians working on turbocharged exhaust repairs, this Dorman down pipe provides a direct replacement-style solution for select applications, including Chevrolet and GMC vehicles where the original pipe needs attention.

Key Features

• Stainless steel construction for long-term exhaust durability
• 3-inch outside diameter for turbocharger exhaust routing
• 1.6 wall thickness for added material strength
• Natural finish
• Irregular shape to match application-specific exhaust routing
• Mounting bracket not included
• Part number 674-5009 for ordering and service reference

Detailed Description

This turbocharger down pipe is intended for exhaust system repair where the factory pipe has corrosion, damage, or fitment issues. The stainless steel construction and application-specific shape support a reliable replacement in turbocharged exhaust layouts. Use Dorman 674-5009 when servicing vehicles that require a 3-inch stainless down pipe with the listed configuration.

This part cross-references GM OE 22216914 for the same application. It is a practical choice for Chevrolet and GMC repair work where the original down pipe needs replacement and the technician needs a direct-reference part number match.

What It Helps Fix

• Exhaust leaks caused by rusted or cracked down pipe sections
• Restricted turbocharger exhaust flow from damaged piping
• Noise from a failing or separated exhaust connection
• Fitment issues after corrosion has distorted the original pipe
• Service delays when the OE pipe is no longer reusable

Installation Notes and Tips

Verify the vehicle’s exhaust routing, turbocharger connection points, and pipe diameter before installation. Because mounting bracket is not included, confirm whether the existing bracket can be reused on the vehicle. For best results, inspect adjoining exhaust components, gaskets, and fasteners during replacement to avoid repeat labor.

Compatible with select Chevrolet and GMC turbocharger exhaust applications; confirm the OE reference 22216914 and the vehicle’s original pipe configuration before ordering. Part number 674-5009 is the key service reference for this down pipe.

Quality Assurance

Dorman manufactures replacement parts for service applications where OE-style fit and material selection matter. This down pipe uses stainless steel construction to support durability in exhaust service.
