Detailed Breakdown: Top Exhaust Options for the 2019–2024 Chevy Malibu
1. Borla Cat-Back Exhaust System — Best for Performance
If you want the absolute best the aftermarket has to offer for your Malibu, Borla is the name that keeps coming up. Known for their race-proven engineering and iconic exhaust tone, Borla cat-back systems are built from T-304 aircraft-grade stainless steel — the same material used in high-performance racing applications. This means superior corrosion resistance and a system built to outlast your vehicle.
For the 2019–2024 Chevy Malibu 2.0T, a Borla ATAK or S-Type system delivers a noticeably deeper, more aggressive exhaust note without crossing into obnoxious drone territory during highway cruising. The mandrel-bent tubing maximizes exhaust flow, which helps the turbocharged engine breathe easier and can translate into modest horsepower and torque improvements. Installation is a bolt-on affair with no cutting required on most trims.
- Pros: Premium T-304 stainless steel, million-mile warranty, excellent sound tuning, real performance gains
- Cons: Premium price point, may be overkill for the 1.5T base engine

2. MagnaFlow Cat-Back Exhaust — Best Balanced Upgrade
MagnaFlow is arguably the most recognized name in aftermarket exhaust, and for good reason. Their cat-back systems for the 2019–2024 Chevy Malibu strike the perfect balance between improved sound, performance, and everyday drivability. If you want your Malibu to sound noticeably sportier without turning heads in a parking garage, MagnaFlow hits that sweet spot.
MagnaFlow uses 409 stainless steel construction, which offers solid rust resistance at a more accessible price point than premium T-304 systems. Their straight-through muffler design reduces backpressure and creates their signature deep, smooth exhaust tone. Unlike some aggressive systems, MagnaFlow is known for virtually zero interior drone — a big deal if you’re commuting daily in your Malibu. The systems are CARB-compliant in most configurations and include all necessary hardware for a clean installation.
- Pros: Excellent brand reputation, sporty-but-refined sound, drone-free daily driving, limited lifetime warranty
- Cons: Not as aggressive as Borla, 409 steel is less corrosion-resistant than T-304

3. Walker OEM Replacement Exhaust — Best Budget Option
Not everyone is looking to transform their Malibu into a track-day machine. If your factory exhaust has rusted through or sprung a leak and you simply want a reliable, quiet, factory-equivalent replacement, Walker is the brand to trust. Walker has been supplying OEM-quality exhaust components for decades and is a go-to choice for dealerships and independent shops alike.
Walker offers individual components — mufflers, pipes, and converters — as well as full exhaust assemblies built to match the exact specifications of your 2019–2024 Malibu. The aluminized steel construction provides adequate protection against rust in most climates, though it won’t match the longevity of stainless steel options. The sound profile is nearly identical to stock, which is exactly what most OEM replacement buyers want.
- Pros: Affordable, OEM-match fit and finish, widely available, great for resale or lease returns
- Cons: No performance improvement, aluminized steel less durable in salt-belt states, no sound enhancement

Which Exhaust Should You Buy for Your Chevy Malibu?
The right exhaust depends entirely on what you want from your Malibu:
- Choose Borla if you own the 2.0T Malibu Premier or RS, you want maximum performance and the best possible exhaust note, and you plan to keep the car long-term. The million-mile warranty means you’re buying once.
- Choose MagnaFlow if you want a noticeable upgrade in sound and modest performance improvement without going full race-car. It’s the best value in the performance category and won’t drone on your morning commute.
- Choose Walker if your current exhaust has failed and you just need a reliable, quiet replacement at a budget-friendly price. Perfect for lease returns, high-mileage Malibus, or anyone who prefers stock-like behavior.
Our Top Pick: For most Malibu owners looking to upgrade, we recommend the MagnaFlow Cat-Back as the best all-around choice. It delivers real improvements in sound and performance, fits perfectly, and won’t break the bank. Check today’s pricing on MagnaFlow for your Malibu here.
Frequently Asked Questions: Exhaust Upgrades for Chevy Malibu 2019–2024
Will a cat-back exhaust void my Chevy Malibu warranty?
Under the Magnuson-Moss Warranty Act, a dealer cannot void your warranty simply because you installed an aftermarket exhaust. However, if an exhaust-related component fails and the dealer can prove the aftermarket exhaust caused the damage, that specific repair may not be covered. Cat-back systems (which start after the catalytic converter) are generally considered the safest exhaust upgrade for warranty preservation.
Is the Chevy Malibu 1.5T or 2.0T better suited for an exhaust upgrade?
Both engines benefit from exhaust upgrades, but the 2.0T responds more noticeably due to its higher output and greater potential for airflow improvement. The 1.5T will see more of a sound improvement than a power gain. If performance is your goal, focus your budget on the 2.0T models (L or Premier trim with the optional engine).
Can I install a Malibu cat-back exhaust myself?
Yes, most cat-back exhaust systems for the 2019–2024 Chevy Malibu are designed as bolt-on installations requiring no cutting or welding. You’ll need basic hand tools, penetrating oil for corroded factory bolts, and a vehicle lift or sturdy jack stands. Most installs take 1–3 hours for a moderately experienced DIYer.
How much horsepower can I gain from a Malibu exhaust upgrade?
A cat-back exhaust alone typically adds 5–15 horsepower on turbocharged engines like the Malibu 2.0T, depending on the system. Pairing the exhaust with an aftermarket intake and a performance tune can yield significantly greater gains. Cat-back systems alone on the 1.5T are more likely to add 3–8 horsepower.
Does a louder exhaust pass emissions testing?
Cat-back exhaust systems do not affect catalytic converters or oxygen sensors, so they generally pass emissions testing without issue. Always verify that the system you purchase is CARB-compliant if you live in California or a state that follows California emissions standards. Brands like MagnaFlow clearly label CARB-compliant products.
