If you’re shopping for an exhaust system for your Nissan Altima 2019-2024, you already know that the right upgrade can do more than just sound good — it can improve throttle response, bump up horsepower, and give your sedan a sportier personality without a full engine build. The 7th-generation Altima, powered by the 2.5L four-cylinder (VC-Turbo or naturally aspirated), is a solid platform for exhaust work, and there’s no shortage of quality options on the market. The challenge is narrowing it down to what actually fits, performs, and lasts.
We’ve broken down three of the most popular aftermarket exhaust brands for the 2019-2024 Nissan Altima — MagnaFlow, Borla, and Walker — so you can make a confident, informed decision before you buy.
[CTA_BUTTON:magnaflow-nissan-altima-exhaust:MagnaFlow Altima Exhaust]
| Feature | MagnaFlow | Borla | Walker |
|---|---|---|---|
| Type | Cat-Back / Muffler | Cat-Back | Direct-Fit Muffler / Replacement |
| Material | 304 Stainless Steel | T-304 Stainless Steel | Aluminized / Stainless Options |
| Sound Level | Moderate-Aggressive | Aggressive / Throaty | OEM-Quiet / Mild |
| Performance Gain | Moderate | Moderate-High | Minimal (OEM Replacement) |
| Warranty | Limited Lifetime | Limited Million-Mile | Limited (1-2 Years Typical) |
| Install Difficulty | Moderate (Bolt-On) | Moderate (Bolt-On) | Easy (Direct-Fit) |
| Best For | Daily Driver + Light Performance | Performance Enthusiasts | OEM Replacement / Budget |
| Price Range | $$–$$$ | $$$–$$$$ | $–$$ |
MagnaFlow is one of the most respected names in the aftermarket exhaust world, and for good reason. Their systems for the 2019-2024 Nissan Altima are built from 304 stainless steel with straight-through, perforated core muffler technology that flows exhaust gases more freely than a restrictive stock unit. The result is a noticeable improvement in exhaust scavenging, which translates to modest horsepower and torque gains — especially appreciated in the 2.5L naturally aspirated version of the Altima.
Sound-wise, MagnaFlow sits in a sweet spot: deeper and more assertive than stock, but not obnoxious on a daily commute. It’s the exhaust you’d want if you still pick up the kids from school but also enjoy the occasional spirited on-ramp run.
Best for: Altima owners who want a noticeable upgrade in sound and mild performance without going overboard.

Borla takes things up a notch. Known for their patented straight-through and multi-core technology, Borla exhaust systems are engineered for maximum exhaust flow efficiency. On the 2019-2024 Nissan Altima — particularly the turbocharged 2.0L VC-Turbo variant — a Borla cat-back can unlock a bit more top-end breathing, giving the engine more room to rev cleanly.
The sound profile on a Borla is genuinely exciting. Depending on the series you choose (ATAK® for max volume, S-Type for a balanced tone, or Touring for a refined note), you can dial in exactly the acoustic experience you want. All Borla products are made in the USA from T-304 stainless steel and backed by their industry-famous million-mile warranty.
Installation is bolt-on for most Altima configurations, though fitment should be verified by trim and engine variant before purchasing — the 2.5L FWD and all-wheel-drive VC-Turbo models may have slightly different routing requirements.
Best for: Altima owners who prioritize performance gains and want a genuine exhaust note upgrade, especially on the VC-Turbo model.

Not every Altima owner needs a performance upgrade. If your factory exhaust has rusted out, developed a leak, or simply given up after years of salt-belt winters, a Walker direct-fit replacement is the most practical and affordable fix. Walker is a trusted OEM-quality brand that offers aluminized steel and stainless steel muffler options designed to match the exact dimensions and hangers of the original Nissan exhaust system.
Installation is as straightforward as exhaust work gets — everything lines up correctly, and most DIYers with basic tools can complete a Walker muffler swap in under two hours. The sound remains close to stock, and emissions compliance is maintained without any modifications.
Best for: Altima owners who just need a reliable factory-replacement exhaust without spending premium money.

Your ideal exhaust comes down to three things: budget, goals, and driving style. Here’s a quick decision guide:
Whichever route you go, always double-check fitment by your specific model year, engine code (QR25DE 2.5L or KR20DDET 2.0T), and drivetrain (FWD vs. AWD) before ordering. Exhaust routing and hanger placement can differ between configurations on the 7th-gen Altima.

Under the Magnuson-Moss Warranty Act, a dealer cannot void your warranty simply because you installed an aftermarket exhaust. However, if an exhaust modification directly causes a specific component to fail, that particular claim could be denied. For peace of mind, choose a reputable brand like MagnaFlow or Borla and keep installation records.
On a naturally aspirated 2.5L Altima, expect modest gains — typically in the range of 5-15 horsepower depending on the system. The turbocharged 2.0T VC-Turbo can see slightly higher gains because improved exhaust flow complements turbo spool characteristics. Results vary and are rarely dramatic without supporting modifications.
Cat-back exhaust systems do not remove or modify catalytic converters, so they are generally street-legal in most U.S. states. However, some states (particularly California) have strict noise and emissions regulations. Always verify your state’s laws and look for CARB-compliant options if you’re in California.
Most cat-back and direct-fit muffler systems are bolt-on installations that a mechanically inclined DIYer can handle with basic hand tools, a floor jack, and jack stands. Rusted hardware on older vehicles can complicate things. If your Altima is a 2019 or newer model, corrosion shouldn’t be a major obstacle yet.
Yes, the AWD Altima (available from 2020 onward on the 2.5L trim) may have slightly different exhaust routing compared to the FWD model. Always confirm fitment using your full VIN or by contacting the manufacturer directly before purchasing a cat-back system.

If you own a 2019–2024 Nissan Altima, keeping up with regular filter replacements is one of the easiest and most impactful maintenance tasks you can do. Whether it’s your oil filter, engine air filter, or cabin air filter, choosing quality filters for your Nissan Altima (2019–2024) directly affects performance, fuel economy, and the air you breathe inside the cabin. With so many brands on the market, it can be tough to know which ones are actually worth your money. We’ve done the homework for you — here’s a straight-talking comparison of the top filter brands for your Altima.
The 2019–2024 Nissan Altima comes equipped with either a 2.0L turbocharged 4-cylinder or the more common 2.5L naturally aspirated 4-cylinder engine. Both engines rely heavily on clean oil and air to deliver the smooth, fuel-efficient performance Altima drivers expect. Let’s dig into the best options available.
| Feature | Bosch | K&N | Fram |
|---|---|---|---|
| Filter Types Available | Oil, Air, Cabin Air | Oil, Air, Cabin Air | Oil, Air, Cabin Air |
| OE Fitment for Altima | ✅ Yes | ✅ Yes | ✅ Yes |
| Reusable/Washable Option | ❌ No | ✅ Yes (Air Filter) | ❌ No |
| Price Range (per filter) | $8–$30 | $15–$65 | $5–$20 |
| Filtration Efficiency | High | High (with slight airflow gain) | Moderate–High |
| Best For | OE-quality replacement | Performance & longevity | Budget-friendly maintenance |
| Warranty | 1 year | 10 years / 1M miles (reusable) | 1 year |
Bosch has been a household name in automotive parts for decades, and their filter lineup for the Nissan Altima lives up to that reputation. Their Bosch Distance Plus Oil Filter and Bosch Workshop Air Filter are designed to meet or exceed OEM specifications — meaning they fit perfectly and perform at least as well as what Nissan installs at the factory.
For the 2019–2024 Altima’s 2.5L engine, the Bosch oil filter features a high-efficiency filter media that traps harmful contaminants before they can cause wear on your engine’s internals. The silicone anti-drain back valve ensures oil doesn’t drain out of the filter between starts — a small but meaningful detail that protects your engine during cold starts.
Their cabin air filter is equally impressive, using a multi-layer filtration design that captures dust, pollen, mold spores, and even some bacteria — great news if you or your passengers suffer from allergies.

If you’re the type of driver who wants to squeeze every bit of efficiency and performance out of your Altima — and hates buying the same part over and over — K&N is a brand worth serious consideration. K&N’s reusable, washable High-Performance Air Filter for the 2019–2024 Nissan Altima is one of their most popular products, and for good reason.
Unlike disposable paper air filters that need replacing every 15,000–30,000 miles, K&N’s oiled cotton gauze air filter can be cleaned and reused for up to 50,000 miles between cleanings, and the filter itself is backed by a remarkable 10-year/1 million mile warranty. Over the life of your Altima, this can save you significant money and hassle.
K&N also produces quality oil filters for the Altima, featuring a rolled steel housing, 17-point anti-drain back valve, and a nut welded to the end cap for easy removal — a practical touch any DIY mechanic will appreciate.
For cabin air filtration, K&N’s VentilationMax cabin air filter uses an electrostatically charged, multi-layer design that captures particulates while maintaining strong airflow — so you’re not sacrificing HVAC performance for cleaner air.

Not everyone wants to spend top dollar on filters, and that’s perfectly reasonable — especially if you’re keeping up with oil changes every 5,000–7,500 miles as Nissan recommends. Fram has long been the go-to brand for budget-conscious car owners, and their filters for the 2019–2024 Nissan Altima deliver solid, dependable performance without breaking the bank.
The Fram Extra Guard Oil Filter uses a Sure-Grip textured surface for no-slip installation and removal, and its cellulose filter media provides adequate protection for standard driving conditions. If you’re doing conventional oil changes on a regular schedule, Fram will get the job done.
Their Fresh Breeze Cabin Air Filter — infused with Arm & Hammer baking soda — is a popular choice for odor control, making it a great pick if your cabin tends to hold onto stale smells. It’s one of the few cabin filters that actively fights odors rather than just filtering particulates.

The right choice really depends on your driving habits, budget, and maintenance philosophy. Here’s a quick guide:
Our top pick? For most 2019–2024 Nissan Altima owners, Bosch hits the sweet spot of quality, fitment reliability, and price. But if you’re ready to invest upfront and stop thinking about your air filter for the next decade, K&N is hard to beat.
Nissan recommends changing the oil and oil filter every 5,000 miles if using conventional oil, or every 7,500–10,000 miles with full synthetic oil. Always replace the oil filter at every oil change for best results.
For a standard disposable air filter, plan on replacement every 15,000–30,000 miles, depending on driving conditions. If you drive in dusty environments, check it more frequently. K&N’s reusable filter only needs cleaning every 50,000 miles.
Nissan recommends replacing the cabin air filter every 15,000 miles or once a year, whichever comes first. If you notice reduced airflow from your vents or musty smells, it’s time to replace it regardless of mileage.
The 2019–2024 Nissan Altima 2.5L engine uses a cartridge-style oil filter. Always verify fitment using your vehicle’s year, make, model, and engine size before purchasing to ensure compatibility.
Yes. Under the Magnuson-Moss Warranty Act in the United States, using aftermarket filters does not void your vehicle warranty, provided the filter meets the OEM specifications. Brands like Bosch, K&N, and Fram all produce filters that meet or exceed Nissan’s requirements.
For many Altima owners, yes. While the upfront cost is higher, a K&N reusable air filter can last the lifetime of the vehicle with proper cleaning. Over 100,000+ miles, you’ll likely save money compared to buying multiple disposable filters — and you’ll never be caught without a filter in stock.
