Detailed Breakdown: Each Exhaust System Reviewed
1. Borla ATAK & S-Type Cat-Back Exhaust — Best Overall
Borla has built an unmatched reputation in the performance exhaust world, and their JL Wrangler-specific systems live up to the hype. The Borla ATAK is built for Wrangler owners who want everyone on the trail — and the highway — to hear them coming. The Borla S-Type offers that same premium build quality with a slightly more refined sound profile for daily drivers who still want presence without going full rock-concert volume.
Both systems are constructed from aircraft-quality T-304 stainless steel, meaning they’ll handle mud, water crossings, and the general abuse a Wrangler sees on and off-road without rusting out. The multi-core technology Borla uses virtually eliminates drone, which is a serious concern for Wrangler owners who put highway miles on their rigs.
- Pros: Premium build quality, minimal drone, aggressive sound, million-mile warranty
- Cons: Highest price point of the three, may be louder than some prefer for daily driving
- Best For: Enthusiasts who want the absolute best and plan to keep their Wrangler long-term

2. Flowmaster American Thunder Cat-Back Exhaust — Best Value
Flowmaster is a legend in the exhaust game, and the American Thunder series for the 2018–2024 Jeep Wrangler JL is a crowd-pleaser for good reason. If you want that deep, classic rumble without spending premium dollars, Flowmaster delivers exactly that. This system produces one of the most recognizable exhaust notes on the market — a bold, throaty tone that suits the Wrangler’s personality perfectly.
Available in aluminized steel (more affordable) and stainless steel options, Flowmaster gives you flexibility depending on your budget and how long you plan to own the vehicle. Installation is straightforward with factory mounting points, making it a solid weekend-warrior DIY project.
The one thing to know going in: Flowmaster systems, especially the more aggressive Delta Flow designs, can produce some cabin drone at steady highway speeds (typically around 65–75 mph). For a Wrangler that’s mostly trail-bound, this is a non-issue. For a daily highway commuter, it’s worth considering.
- Pros: Excellent value, iconic exhaust sound, easy installation, wide product range
- Cons: Potential drone at highway speeds, aluminized versions less durable long-term
- Best For: Budget-conscious Wrangler owners who want maximum sound impact per dollar

3. MagnaFlow Street Series Cat-Back Exhaust — Best for Daily Drivers
MagnaFlow occupies the sweet spot between Flowmaster’s boldness and Borla’s premium refinement. The MagnaFlow Street Series for the 2018–2024 Jeep Wrangler JL is engineered for drivers who want a noticeable upgrade over stock without sacrificing everyday livability. The tone is deep and confident — a low, smooth rumble that sounds purposeful without being obnoxious during a morning commute.
All MagnaFlow systems are built from 304 stainless steel with a polished finish, and the brand’s straight-through muffler design does a great job at reducing backpressure for a modest bump in horsepower and torque. If you’re running a 3.6L Pentastar V6 or the 2.0L turbocharged four-cylinder, MagnaFlow has specific fitments for both engines across the JL generation.
- Pros: Low drone, refined sound, all-stainless construction, great daily driver balance
- Cons: Sound may feel too mild for hardcore off-road enthusiasts wanting max aggression
- Best For: Wrangler owners who split time between daily driving and weekend trail runs

Which Jeep Wrangler Exhaust Should You Buy?
Here’s the bottom line based on your priorities:
- Choose Borla if you want the absolute best long-term investment, premium sound quality, and minimal drone. The million-mile warranty alone is worth the price premium for a Wrangler you plan to keep for years.
- Choose Flowmaster if you’re on a tighter budget and want the loudest, most aggressive sound character for the money. Perfect for trail rigs and weekend warriors who don’t mind a little highway drone.
- Choose MagnaFlow if you daily drive your Wrangler and want a polished, all-stainless system that sounds great without droning on long highway stretches. It’s the most versatile pick for mixed-use Wranglers.
No matter which brand you go with, any of these three systems will be a massive improvement over the stock Jeep exhaust. The 2018–2024 JL Wrangler responds well to exhaust upgrades on both the 3.6L V6 and 2.0T four-cylinder engines, so you’ll gain both sound and performance regardless of your choice.

Frequently Asked Questions: Jeep Wrangler Exhaust Systems
Will a cat-back exhaust void my Jeep Wrangler’s warranty?
In most cases, a cat-back exhaust will not void your Jeep Wrangler’s powertrain warranty. Under the Magnuson-Moss Warranty Act, a dealer must prove the aftermarket part caused a specific failure to deny a warranty claim. However, removing the catalytic converter or modifying emissions equipment could cause issues. Always check with your dealer and choose reputable brands like Borla, Flowmaster, or MagnaFlow that are designed to meet or exceed emissions standards.
How much horsepower does an exhaust add to a Jeep Wrangler?
A cat-back exhaust system typically adds between 5 and 15 horsepower to a 2018–2024 Jeep Wrangler, depending on the engine and specific system. The gains are most noticeable when paired with other modifications like a cold air intake and a tune. The 3.6L Pentastar V6 and 2.0L turbo four-cylinder both respond positively to exhaust upgrades.
Can I install a Jeep Wrangler exhaust system myself?
Yes! Most cat-back exhaust systems for the 2018–2024 Jeep Wrangler JL are designed for DIY installation and use factory hangers and bolt-on connections. With basic hand tools, a floor jack, and about 2–3 hours of time, most mechanically inclined Wrangler owners can complete the install at home. Always use penetrating oil on the factory bolts beforehand, as they can be corroded — especially on older or off-road-used vehicles.
Does the Jeep Wrangler 4xe (plug-in hybrid) support aftermarket exhaust upgrades?
The Jeep Wrangler 4xe uses a 2.0L turbocharged four-cylinder with an electric motor assist. While some aftermarket exhaust brands are developing fitment-specific options for the 4xe, availability is more limited compared to the standard JL models. Always confirm fitment compatibility with the manufacturer before purchasing if you own a 4xe model.
What’s the difference between a cat-back and an axle-back exhaust for a Jeep Wrangler?
A cat-back exhaust replaces everything from the catalytic converter back, including the mid-pipe, muffler, and tip — offering greater performance and sound gains. An axle-back exhaust only replaces the section from the rear axle back (muffler and tip), making it easier to install and less expensive, but with more modest results. For maximum sound and performance improvement on a 2018–2024 Jeep Wrangler, a cat-back system is the recommended choice.
