The A-Premium Exhaust Manifold Kit is EPA compliant for federal emissions standards. While it meets these federal requirements, it is not listed as CARB legal for use in California, New York, Colorado, or Maine.
The Nissan Altima Exhaust Kit meets federal requirements but lacks the specific certification required for restricted states like California. Because emissions laws vary by region, you must confirm your local requirements before ordering to avoid potential fines or impoundment. We selected this kit for our comparison because it provides a stainless steel construction and includes both front and rear positions. The kit includes the necessary gaskets and bolts for a complete installation, which prevents the need for additional hardware sourcing. While the kit is designed for the 2007-2012 Nissan Altima 2.5L, the specific catalyst coating material and any required “break-in” heat-cycling procedures are not listed in the provided data; you should consult the manufacturer’s support page for these technical details. This exhaust manifold converter, which is a metal pipe that filters engine gases before they exit the vehicle, is designed to bolt directly to the engine head using specific OE part numbers like 16593 and 40800.
What to Check Before Buying the Altima Exhaust Kit
Verify these technical details to ensure the manifold functions correctly on your specific vehicle:
- Confirm your state’s emissions laws to see if federal EPA compliance is sufficient or if CARB certification is required.
- Verify that your engine’s heat shield provides enough clearance for the manifold to mount without interference.
- Check with the manufacturer to confirm if the specific catalyst coating requires a specific heat-cycling procedure to prevent cracking.
- Consult the manufacturer’s compatibility page to confirm that the unit will not trigger a Check Engine Light (CEL) or require an ECU reflash.
- Ensure the manifold geometry aligns with your engine block casting by cross-referencing your current OE part numbers.
Comparing the Altima Exhaust Kit to Other Manifold Options
The Altima Exhaust Kit serves as a direct replacement for the factory exhaust manifold and converter. Buyers looking for a high-flow performance upgrade or a specific high-flow ceramic substrate might find other options better suited to their needs, as this unit focuses on standard federal compliance. If you require a manifold that is specifically engineered for extreme high-load heat dissipation or different substrate materials, you may want to look for alternatives that specify those material standards. For most owners simply seeking a durable, stainless steel replacement that meets federal standards, this kit provides the necessary hardware and fitment for the 2.5L engine.

If you live in a state that follows federal emissions standards and need a durable stainless steel replacement that includes all necessary mounting hardware, choose the Altima Exhaust Kit.
