Finding the Best Exhaust System for Nissan Altima 2019-2024

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.

Detailed Breakdown: Each Exhaust Option for the 2019-2024 Altima

1. MagnaFlow — The Best All-Rounder

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.

• Pros: Lifetime warranty, high-quality stainless construction, great daily-driver tone, bolt-on fitment
• Cons: Not the loudest option if you want a race-inspired sound, higher price than OEM replacement

Best for: Altima owners who want a noticeable upgrade in sound and mild performance without going overboard.

2. Borla — For the Performance-Minded Altima Driver

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.

• Pros: Million-mile warranty, aggressive sound options, excellent build quality, USA-made
• Cons: Premium price, may be louder than some owners prefer for daily driving

Best for: Altima owners who prioritize performance gains and want a genuine exhaust note upgrade, especially on the VC-Turbo model.

3. Walker — The Smart OEM Replacement Choice

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.

• Pros: Affordable, easy bolt-on fitment, OEM-correct dimensions, widely available
• Cons: No performance or sound enhancement, shorter warranty than premium brands

Best for: Altima owners who just need a reliable factory-replacement exhaust without spending premium money.

Which Exhaust Should You Buy for Your 2019-2024 Nissan Altima?

Your ideal exhaust comes down to three things: budget, goals, and driving style. Here’s a quick decision guide:

• Choose MagnaFlow if you want a noticeable upgrade in sound and a mild performance boost while keeping your Altima daily-driver friendly. It’s the most balanced choice for most owners.
• Choose Borla if you have the budget and want the best possible performance gains and a more aggressive exhaust note — especially if you’re driving the 2.0L VC-Turbo Altima and want to maximize what that turbocharged engine can do.
• Choose Walker if your factory exhaust has failed and you just need a cost-effective, no-fuss replacement that keeps your car running and sounding like it did from the dealership.

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.

Frequently Asked Questions

Will an aftermarket exhaust void my Nissan Altima warranty?

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.

How much horsepower can I gain from a cat-back exhaust on the 2019-2024 Altima?

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.

Is a cat-back exhaust legal for street use?

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.

Can I install an Altima exhaust myself?

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.

Does the AWD Nissan Altima use a different exhaust than the FWD model?

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.
