Nissan Exhaust Headers
Shop Nissan exhaust headers for selected 240SX, 350Z, 370Z, G35, G37, Sentra SE-R Spec V, D21 pickup, 280Z, 280ZX, and Altima applications. A vehicle-specific header replaces the factory exhaust manifold section and can support smoother exhaust flow for repairs, restorations, and performance-oriented builds.
This collection includes headers for selected KA-series, QR25DE, VQ35DE, VQ37VHR, and L-series Nissan engines. Fitment can vary by model year, chassis, transmission, oxygen-sensor layout, and the connection to the remaining exhaust system. Confirm the full product listing before ordering.
Shop Nissan Headers by Vehicle and Engine
Use the guide below to narrow your options, then verify the specific product’s complete fitment information before ordering.
| Nissan Engine | Selected Applications | What to Confirm Before Ordering |
|---|---|---|
| KA24E | Selected 1990–1995 Nissan D21 / Hardbody pickup models | Verify the engine is the Nissan KA24E. Check whether the truck retains its original engine and exhaust layout. |
| KA24DE | Selected 1995–1998 Nissan 240SX models | Confirm the S14 chassis, engine configuration, transmission, and header outlet connection to the front pipe. |
| QR25DE | Selected 2002–2006 Sentra SE-R / Spec V and Altima 2.5L applications | Check the exact model, year, and engine. Sentra and Altima headers may use different routing and connection points. |
| VQ35DE | Selected 2003–2006 Nissan 350Z and Infiniti G35 models | Confirm the model year, coupe or sedan configuration where applicable, transmission, and whether the car uses its original exhaust components. |
| VQ37VHR | Selected 2009–2013 Nissan 370Z and Infiniti G37 models | Verify the exact model year, chassis, transmission, and downstream exhaust connection. |
| L-Series Inline-Six | Selected Nissan 280Z and 280ZX applications | Confirm engine type, production year, steering clearance, and the connection to the existing exhaust system. |
The vehicle name alone is not enough to confirm compatibility. Before purchase, check the engine code, model year, chassis, transmission, oxygen-sensor locations, flange design, and any prior exhaust modifications. For engine-swapped or custom-exhaust vehicles, compare the product dimensions and outlet configuration with the parts currently installed.
