What to quote
State the quantity of exhaust muffler and the agreed assembly contents for each application. Identify pieces per set and any separately priced hardware before comparing quotations.
Nissan Navara · Engine, Cooling & A/C
Use cab, wheelbase and engine to define the silencer section. Record hanger spacing, pipe diameter and any modified rear bumper or tray clearance.

| Record | Details to retain |
|---|---|
| Body, wheelbase and engine | Identify body, wheelbase and engine from the vehicle and installed assembly, retaining readable labels. |
| Pipe diameter and section boundary | Show pipe diameter and section boundary in photographs and provide the dimensions needed to compare the interfaces. |
| Flanges and hanger positions | Specify flanges and hanger positions in the requested contents so offers refer to the same assembly. |
A cab-chassis exhaust tail section may differ from a factory pickup-bed arrangement.
For exhaust muffler, keep the full chassis identifier and build record with the request. The Navara chassis and market guide separates D22, D40, D23 and D27 identification; neither NP300 nor Frontier naming alone proves compatibility.
When exhaust muffler is quoted with related assemblies, use the fuel, cooling and electrical systems guide to keep their requirements distinct.
Send clear overall and mounting or connection photographs. For this exhaust muffler inquiry, retain pipe diameter and section boundary; mark unknown dimensions instead of borrowing a number from a different generation. The OE and vehicle-identification checklist helps organize the information.
Treat every linked assembly as a separate order line from the exhaust muffler; approving one component does not confirm the others.
Navara Catalytic Converter — retain engine, emission market and bank and manifold or underfloor position for that assembly.
Navara Rear Bumper — retain pickup bed or aftermarket tray and step, sensor and bracket geometry for that assembly.
Navara Engine Mount — retain installed engine and mount position and bracket and stud geometry for that assembly.
Navara EGR Valve — retain engine and emission version and actuator and valve interface for that assembly.
State the quantity of exhaust muffler and the agreed assembly contents for each application. Identify pieces per set and any separately priced hardware before comparing quotations.
Protect hangers and pipe ends with rigid supports.
Before approving the exhaust muffler, agree sample and inspection requirements using the quality-control checklist. Return to the Navara component directory for other systems.
