Top Exhaust Picks for the 2019–2024 Nissan Altima

1. Borla S-Type Cat-Back Exhaust — Best Overall

When it comes to premium exhaust systems, Borla is a name that needs no introduction. The Borla S-Type Cat-Back is widely considered one of the best options for the 2019–2024 Nissan Altima, delivering a deep, aggressive exhaust note that sounds purposeful without crossing into drone territory on the highway. Built from aircraft-quality T-304 stainless steel, this system is engineered for longevity and backed by Borla’s industry-leading million-mile warranty.

The S-Type is specifically designed to improve exhaust scavenging — pulling spent gases out of the engine more efficiently — which translates to modest horsepower and torque gains you can actually feel, especially in the 2.0T Altima. The polished dual tips add a clean, sporty look to the rear of the car without looking overdone.

2. MagnaFlow Street Series Cat-Back — Best for Daily Drivers

MagnaFlow has built its reputation on producing exhaust systems that sound great without turning heads for the wrong reasons. The MagnaFlow Street Series Cat-Back for the Nissan Altima offers a refined, deeper exhaust note that enhances the car’s character without being obnoxious in traffic or on long highway cruises. Made with 409 stainless steel and featuring MagnaFlow’s signature straight-through muffler design, this system promotes excellent exhaust flow.

If you’re a daily driver who wants a noticeable but tasteful upgrade over the flat stock sound, this is your system. It’s also one of the most straightforward bolt-on installs you’ll find in this category.

3. Flowmaster Super 44 Axle-Back — Best Budget Sound Upgrade

If you want a dramatic sound upgrade without spending a fortune, the Flowmaster Super 44 Axle-Back system is hard to beat. Known for its iconic American muscle rumble, the Super 44 muffler delivers an aggressive, throaty exhaust note that will completely transform the Altima’s personality. The axle-back configuration means you’re only replacing the rear section of the exhaust — keeping costs and installation time low.

Keep in mind that Flowmaster’s aggressive tuning can produce more interior drone at certain RPMs compared to Borla or MagnaFlow, but for weekend drivers and enthusiasts who want maximum sound for their dollar, this is a fantastic option.

4. MBRP Installer Series Cat-Back — Best Value Cat-Back

The MBRP Installer Series hits a sweet spot between price and performance that makes it a go-to choice for Altima owners who want a full cat-back system without breaking the bank. MBRP uses aluminized steel on this entry-level lineup, which keeps costs down while still providing solid corrosion resistance for most climates. The sound profile is mild to moderate — a step up from stock but far from intrusive.

This is a great option if you’re pairing your exhaust upgrade with other bolt-ons like a cold air intake and want improved overall exhaust flow to support those other mods.

5. Gibson Performance Cat-Back — Best for Power Seekers

Gibson Performance takes a different engineering approach by focusing heavily on flow optimization and power output. Their cat-back systems for the Nissan Altima are built with mandrel-bent stainless tubing to ensure smooth, unrestricted exhaust flow from the catalytic converter to the tip. On turbocharged 2.0T Altimas, this can yield measurable gains in horsepower and torque, making Gibson a compelling choice for performance-minded owners.

Exhaust Buying Guide: What to Know Before You Buy for a 2019–2024 Nissan Altima

Cat-Back vs. Axle-Back: Which Do You Need?

A cat-back exhaust replaces everything from the catalytic converter outlet to the exhaust tips — including the mid-pipe and muffler. This gives you the most exhaust flow improvement and the best power gains. An axle-back system only replaces the muffler and tips behind the rear axle. Axle-back systems are cheaper and easier to install but offer minimal performance improvement — mostly sound upgrades.

Recommendation: If power gains matter to you, go cat-back. If you want sound on a budget, axle-back is perfectly fine.

Engine Matters: 2.5L vs. 2.0T

The 2019–2024 Nissan Altima is available with two engine options:

Always confirm the exhaust system you choose is designed for your specific engine. Fitment varies between these two configurations.

Material: Stainless vs. Aluminized Steel

Sound Level: Setting Realistic Expectations

Exhaust sound is subjective. On a 4-cylinder Altima, you won’t get a V8 rumble — but a quality system will replace the stock drone with a refined, sporty tone. Watch YouTube sound clips for your specific system before purchasing to make sure it matches your expectations.

Brief Installation Overview

Most cat-back and axle-back exhaust systems for the 2019–2024 Nissan Altima are designed as direct bolt-on replacements and can be installed with basic hand tools in 1–3 hours. Here’s a general process:

  1. Safety first — Ensure the exhaust is completely cool before starting. Use jack stands, never just a floor jack.
  2. Remove the old system — Loosen the clamps or flanges at the cat connection point and hangers along the undercarriage. Penetrating oil (like PB Blaster) is your best friend on older hardware.
  3. Install the new system — Slide the new tubing into place, hang it on the rubber isolators, and loosely tighten all hardware first.
  4. Align and torque — With everything loosely in place, adjust tip angle and centering before final tightening.
  5. Start and check — Let the car idle and listen for exhaust leaks at connection points. Re-tighten if necessary.

Note: Professional installation is always recommended if you’re unsure, especially for cat-back systems that include mid-pipe work.

Frequently Asked Questions

Will an aftermarket exhaust void my Nissan Altima’s warranty?

Under the Magnuson-Moss Warranty Act, a dealer cannot void your powertrain warranty simply because you installed an aftermarket exhaust — unless they can prove the exhaust directly caused the failure in question. However, emissions-related components may be affected in some states. Always check your local regulations.

How much horsepower does an exhaust add to a Nissan Altima?

On a naturally aspirated 2.5L Altima, gains are typically modest — anywhere from 3–8 hp. On the 2.0T VC-Turbo, a free-flowing cat-back system can contribute to 8–15 hp gains, especially when combined with a performance tune.

Is a cat-back exhaust legal for street use?

Yes, in most U.S. states, cat-back exhaust systems are street legal because they retain the catalytic converter. However, California and other CARB-compliant states have stricter rules — look for systems with a CARB Executive Order (EO) number if you’re in one of these states.

What size exhaust pipe does the 2019–2024 Altima use?

The factory exhaust on the 2019–2024 Nissan Altima typically uses a 2.25-inch diameter pipe. Most aftermarket cat-back systems upsize this to 2.5 inches for improved flow, which is one of the primary reasons for performance gains.

Can I install an exhaust myself or do I need a shop?

An axle-back system is very DIY-friendly and can be done in a driveway with basic tools. A cat-back system is more involved but still achievable for mechanically inclined owners. If any welding or cutting is required, a muffler shop is recommended.

Final Verdict: Which Exhaust Is Best for Your Nissan Altima?

After reviewing the top options available, here’s our quick-reference verdict:

No matter which system you choose, upgrading the exhaust on your 2019–2024 Nissan Altima is a worthwhile investment that pays dividends every time you turn the key. Drive happy — and drive loud (or not — your call).
