The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.
Tamerx Diesel Products provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.
Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".
If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue.

As is the case for the majority of the diesel products sold on Tamerx Diesel Products, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Tamerx Diesel Products will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.
What is a Core Charge?
A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.
30 Day Core Charge Hold
You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.
"This Product Doesn't Have a Core"
Proper exhaust flow is essential for maintaining engine efficiency, and the Detroit 12.7L Exhaust Manifold 1998–2002, OEM Part Number 2351897, is designed to deliver reliable durability in demanding applications. Engineered for compatibility with select Detroit 12.7L engines, this manifold channels exhaust gases from the cylinders to the turbocharger with secure, leak-free fitment. Manufactured to meet OEM specifications, it ensures accurate alignment and dependable operation under high-temperature conditions. Cracked or leaking exhaust manifolds can lead to excessive noise, reduced engine efficiency, or visible exhaust leaks, making timely replacement important. Tamerx Diesel Products LLC offers trusted diesel components to help keep your Detroit engine operating smoothly and reliably.

The Detroit 12.7L Exhaust Manifold OEM 2351897 is a cast assembly that collects exhaust gases from the engine’s cylinders and directs them toward the turbocharger and exhaust system. While it appears as a single unit, the exhaust manifold is composed of several integral features and associated parts that allow it to function effectively in heavy-duty diesel applications.
Primary Manifold Components
- Cast Manifold Body
- The main structure that connects to each exhaust port on the cylinder head. It collects exhaust pulses from all cylinders.
- Runner Sections
- Individual passageways within the manifold body that guide exhaust gas from each cylinder port into the common outlet.
- Common Outlet / Flange
- The exit point where collected exhaust gases leave the manifold and enter the turbocharger or exhaust piping.
Supporting Features & Hardware
- Mounting Flanges
- Machined surfaces where the manifold bolts to the cylinder head. These provide a secure, sealed connection.
- Heat Shield (if equipped)
- A protective cover that reduces radiant heat exposure to surrounding components.
- Gasket Surfaces
- Mating faces where exhaust gaskets are installed to prevent leaks between the manifold and cylinder head.
- Bolt Holes / Studs
- Fastening points for attaching the manifold to the engine block and turbocharger.
- EGR Port (if applicable)
- Some configurations include an integrated port that routes exhaust gas back to the EGR system.
Sealing & Attachment Components (Installed with the Manifold)
- Exhaust Gaskets
- Thin, heat-resistant seals placed between the manifold and cylinder head, and between the manifold outlet and turbocharger.
- Mounting Bolts / Studs and Nuts
- Hardware used to secure the manifold in place and maintain proper sealing under thermal cycling.
How It Works
Each cylinder expels exhaust gases as the exhaust valve opens during the exhaust stroke. The runner sections in the manifold merge these gas flows into a single outlet. From there, gases move into the turbocharger turbine or the exhaust system for further treatment. The cast design handles extreme heat and thermal shock while maintaining structural integrity.
Even though the OEM 2351897 unit is one complete assembly, its internal runners and flanged interfaces are all critical elements that allow it to guide exhaust efficiently and reliably in Detroit 12.7L applications.
The exhaust manifold directs exhaust gases away from the engine and into the rest of the exhaust system. Because it is exposed to extreme heat and constant expansion and contraction, it can develop cracks or leaks over time.
There is no set replacement interval. Instead, the exhaust manifold should be replaced when damage or leakage is confirmed.
Common signs it may be time for replacement include:
- Ticking or tapping noise from the engine bay, especially on cold starts
- Visible cracks in the manifold
- Exhaust leak smell inside or around the vehicle
- Reduced engine efficiency
- Check engine light related to oxygen sensor readings
- Soot buildup around the manifold area
Small cracks can grow quickly due to repeated heat cycles. Once a crack forms, exhaust gases can escape before reaching the oxygen sensors, affecting engine operation.
Warping is another concern. If the manifold surface is no longer flat, it may not seal properly against the cylinder head, even with a new gasket.
Before replacing the manifold, a thorough inspection is important. A technician will check for gasket failure, broken studs, and related exhaust system issues.
Replacing a damaged exhaust manifold promptly helps prevent further engine and emissions system complications.
Yes, installation of the Detroit 2351897 typically requires new gaskets and proper mounting hardware.
Using the correct OEM 2351897 Exhaust Manifold ensures proper fit, alignment, and long-term exhaust system integrity.
Common indicators include exhaust leaks, unusual engine noise, or visible cracks around the manifold.
Yes, the Detroit 2351897 Exhaust Manifold is engineered to align with the engine’s original exhaust ports and connections.
