The typical price range for replacing a catalytic converter on a 2015 Nissan Altima is about $350–$900 per converter with aftermarket parts, or roughly $750–$1,400 per converter with OEM parts. If both converters need replacement, expect higher totals, generally in the $1,600–$3,000+ range depending on parts and labor. This article breaks down the factors and provides price ranges to help you plan.
Cost breakdown by situation
Single catalytic converter replacement
Before listing price ranges, note that most 2015 Altima models use two catalytic converters in the exhaust system, but replacement may involve a single unit if only one cat is failing.
- Aftermarket direct-fit single cat: Parts roughly $250–$600; labor about 1–2 hours; total typically $350–$900.
- OEM Nissan single cat: Parts roughly $600–$1,000+; labor about 1–2 hours; total typically $750–$1,400.
Prices vary by region, dealer vs independent shop, and vehicle specifics (2.5L vs 3.5L engine). Always obtain a formal quote after a diagnostic.
Two catalytic converters replacement (both cats)
Replacing both catalytic converters is common on older Altimas when both units have degraded or when emissions work requires dual-cat replacement.
- Aftermarket two-cat replacement: Parts roughly $500–$1,200; labor about 2–4 hours; total typically $1,000–$2,400.
- OEM Nissan two-cat replacement: Parts roughly $1,200–$2,000+; labor about 2–4 hours; total typically $1,800–$3,800+.
Again, actual totals depend on the exact engine configuration (2.5L vs 3.5L), the shop’s hourly rate, and whether any sensors or gaskets must be replaced during the job.
What can affect the price?
Several factors can push the final bill up or down, including location, shop rates, and the need for ancillary work. The following considerations commonly influence final pricing.
- Parts choice: aftermarket direct-fit vs OEM Nissan parts; dual-cat vs single-cat configuration.
- Labor rate and time: regional differences and the shop’s efficiency; some cars require additional time due to tight spaces or routing.
- Diagnostic and ancillary work: preliminary diagnosis fees, replacement of O2 sensors or exhaust gaskets, and reprogramming if needed.
- Vehicle condition: rust, corrosion, or damaged exhaust components can add labor and parts costs.
- Local emissions regulations: some regions require specific components or tests that affect cost.
Getting quotes from multiple shops and asking for a breakdown (parts vs labor) helps ensure you’re paying a fair price for your specific Altima and engine configuration.
Tips to save money and ensure a solid repair
- Ask for a diagnostic first to confirm which converters need replacement and whether sensors will be affected.
- Request price quotes that separate parts and labor and specify OEM vs aftermarket parts.
- Consider a trusted independent shop vs a dealership; independents often offer lower labor rates for similar parts.
- Inquire about bundled pricing if both converters need replacement.
Being informed and shopping around can help you balance cost with long-term reliability and emissions requirements.
Summary
Replacing a catalytic converter on a 2015 Nissan Altima typically costs a few hundred dollars per converter with aftermarket parts and somewhat higher with OEM parts. If both converters require replacement, total project costs rise accordingly, with aftermarket totals generally in the low thousands and OEM totals approaching or exceeding the upper three thousand-dollar range in some markets. Always verify the specific engine variant, request a detailed quote, and consider quotes from multiple shops to find the best value while maintaining emissions compliance.
Is $200 good for a catalytic converter?
Catalytic converter prices range from $200 to $2,500, with labor costs from $70 to $130 per hour. Symptoms of a failing catalytic converter include engine power loss, unusual smells, and failing emissions tests. Timely replacement is essential to reduce air pollution and prevent serious engine issues.
Is it worth fixing a catalytic converter?
Repairing or replacing a catalytic converter restores your vehicle's emissions control system to optimal functionality. This not only helps your vehicle run efficiently but also reduces harmful emissions, contributing to a cleaner environment.
Can I still drive with a bad catalytic converter?
While your vehicle may still run with a failing catalytic converter, driving with one for an extended period is not recommended.
