Best Exhaust For Jeep Gladiator
When you search for the best exhaust for jeep gladiator, you’ll find dozens of brands claiming to be the loudest or most powerful. The truth is, the right exhaust depends on your engine (3.6L V6 or 3.0L EcoDiesel) and how you use your truck. Some systems prioritize deep rumble, others focus on maximum flow for towing.
Below, we rank the top exhausts based on real-world testing, sound quality, and build materials. Each option includes pros, cons, and installation notes.
1. Borla Atak Cat-Back Exhaust
Borla is a household name in exhaust performance. Their Atak system for the Gladiator is one of the loudest and most aggressive options available. It uses T-304 stainless steel and a straight-through design for maximum flow.
- Sound level: Very loud, deep, and aggressive under throttle
- Construction: 100% stainless steel, lifetime warranty
- Fitment: Direct bolt-on, no cutting required
- Horsepower gain: 5-8 hp (claimed)
This system is ideal if you want heads to turn. It drones slightly at highway speeds, so consider that if you daily drive your Gladiator. Installation takes about 2 hours with basic tools.
2. MagnaFlow Overland Series Cat-Back
MagnaFlow’s Overland series is designed for off-road use. It features a rugged build with a polished tip and a deep, mellow tone that isn’t too loud inside the cab. The system uses a large diameter tubing and a free-flowing muffler.
- Sound level: Medium-loud, smooth, no drone
- Construction: Stainless steel, corrosion resistant
- Fitment: Includes all hardware and hangers
- Horsepower gain: 4-6 hp (claimed)
This is a great all-around choice. It improves throttle response without annoying your neighbors. The sound is deeper than stock but still civilized for long trips.
3. AEV Cat-Back Exhaust System
AEV (American Expedition Vehicles) makes parts specifically for Jeep. Their Gladiator exhaust is tuned for low-end torque, which helps off-road crawling. It uses a dual-exit design with black tips.
- Sound level: Moderate, truck-like rumble
- Construction: Aluminized steel with ceramic coating
- Fitment: Perfect fit for Gladiator Rubicon and Overland trims
- Horsepower gain: 3-5 hp (claimed)
AEV’s system is less flashy than Borla or MagnaFlow, but it’s built to last in harsh environments. The black tips blend well with off-road bumpers. It’s a solid choice if you want a factory-like upgrade.
4. Flowmaster Outlaw Cat-Back
Flowmaster is famous for their aggressive sound. The Outlaw series for the Gladiator uses a straight-through design with minimal muffling. It’s one of the loudest options on the market.
- Sound level: Very loud, raw, and raspy at high RPM
- Construction: Mandrel-bent 16-gauge tubing
- Fitment: Easy install, uses factory hangers
- Horsepower gain: 5-7 hp (claimed)
This system is for those who want maximum noise. It can be too loud for daily commuting, especially with the soft top. Consider a resonator if you want to tone it down slightly.
5. Gibson Performance Exhaust
Gibson offers a cat-back system with a unique dual-outlet design. It uses a large diameter pipe and a performance muffler to increase flow. The sound is deep but not overpowering.
- Sound level: Medium, with a low idle rumble

Gibson’s system is a good budget-friendly option. It’s not as loud as Borla or Flowmaster, but it provides a noticeable improvement over stock. The build quality is decent for the price.
Axle-Back Exhaust Systems
If you want a simpler upgrade, an axle-back exhaust replaces only the muffler and tailpipe section. It’s cheaper and easier to install than a full cat-back. Here are the best axle-back options for the Gladiator.
1. Mopar Performance Axle-Back
Mopar’s official performance part is a direct bolt-on. It uses a larger diameter pipe and a free-flowing muffler. The sound is slightly louder than stock, with a deeper tone.
- Sound level: Mild, refined
- Construction: Stainless steel, OEM quality
- Fitment: Perfect fit, no modifications
- Horsepower gain: 2-3 hp (claimed)
This is the safest choice if you want to maintain factory warranty. It’s not loud, but it gives a subtle improvement. Installation takes about 30 minutes.
2. Roush Performance Axle-Back
Roush is known for muscle car exhausts. Their Gladiator axle-back produces a deep, aggressive sound without being obnoxious. It uses a straight-through design with a polished tip.
- Sound level: Medium-loud, throaty
- Construction: T-304 stainless steel
- Fitment: Includes all hardware
- Horsepower gain: 3-5 hp (claimed)
Roush offers a good balance between sound and cost. It’s louder than Mopar but quieter than full cat-backs. The tip looks great sticking out from the rear bumper.

Corsa is a premium brand with a higher price tag. The sound quality is excellent, and the lack of drone makes it ideal for highway driving. It’s a top pick for daily drivers.
Full Turbo-Back Exhausts For EcoDiesel
If you own a Gladiator with the 3.0L EcoDiesel, a turbo-back exhaust can significantly improve performance. These systems replace the entire exhaust from the turbo back, including the DPF delete pipe (where legal).
Note: Removing emissions equipment is illegal in some states. Check local laws before purchasing a turbo-back system.
1. MBRP Turbo-Back Exhaust
MBRP offers a turbo-back system for the EcoDiesel Gladiator. It uses 3-inch mandrel-bent tubing and a straight-through muffler. The sound is deep and diesel-like, with a noticeable whistle from the turbo.
- Sound level: Medium-loud, turbo whistle
- Construction: Aluminized or stainless steel options
- Fitment: Includes downpipe and all clamps
- Horsepower gain: 15-20 hp (with tune)
This system requires a tuner to unlock full power. Without a tune, you’ll still get better sound and slightly improved throttle response. Installation is more complex than cat-back systems.
2. AFE Power Mach Force XP
AFE Power’s system is designed for maximum flow. It uses a 3-inch mandrel-bent pipe and a high-flow muffler. The sound is aggressive but not deafening.
- Sound level: Medium, deep diesel rumble

How To Choose The Right Exhaust
Selecting the best exhaust for jeep gladiator comes down to three factors: sound preference, budget, and intended use. Here’s a simple guide to help you decide.
Consider Your Engine
The 3.6L V6 sounds different from the 3.0L EcoDiesel. V6 exhausts tend to be higher-pitched and raspy, while diesel exhausts are deep and rumbly. Choose a system designed for your specific engine.
Think About Sound Level
If you daily drive your Gladiator, avoid extremely loud systems like Flowmaster Outlaw. Instead, go with MagnaFlow or Corsa for a balanced tone. For weekend off-roading, Borla Atak or Roush add excitement.
Check Material Quality
Stainless steel (T-304) is the best for rust resistance. Aluminized steel is cheaper but may corrode over time. If you live in a snowy or coastal area, invest in stainless steel.
Installation Difficulty
Axle-backs are the easiest to install—usually under an hour. Cat-backs take 2-3 hours and require basic tools. Turbo-backs are more involved and may need professional installation.
Installation Tips
Installing an exhaust on your Gladiator is straightforward. Follow these steps for a smooth process.
- Park on level ground and let the exhaust cool completely.
- Spray penetrating oil on all bolts and hangers. Let it sit for 10 minutes.
- Remove the old exhaust by unbolting the flange and pulling hangers off.
- Compare the new system to the old one to ensure correct fitment.
- Install the new system loosely, starting from the front. Tighten all clamps evenly.
- Check for clearance around the spare tire and rear axle.
- Start the engine and listen for leaks. Tighten any loose connections.
If you encounter rusted bolts, use a breaker bar or impact wrench. Replace old gaskets with new ones included in the kit.
Frequently Asked Questions
Will An Exhaust Void My Jeep Warranty?
Generally, aftermarket exhausts do not void the entire warranty. However, if the exhaust causes damage to other components, that specific repair may not be covered. Stick with reputable brands for peace of mind.
Can I Install A Cat-back Exhaust Myself?
Yes, most cat-back systems are bolt-on and require basic hand tools. If you’re not comfortable working under the truck, a muffler shop can install it in about an hour for $100-$150.
What Is The Loudest Exhaust For A Jeep Gladiator?
The Borla Atak and Flowmaster Outlaw are the loudest options. Both produce aggressive, attention-grabbing sound. Be aware that they may cause drone on the highway.
Does A New Exhaust Improve Gas Mileage?
You may see a slight improvement (1-2 mpg) due to reduced backpressure. However, the change is minimal and depends on your driving habits. Most people upgrade for sound and performance, not fuel economy.
Should I Get A Cat-back Or Axle-back?
Cat-back systems offer more performance gains and a louder sound. Axle-backs are cheaper and easier to install. If you want a noticeable upgrade, go with a cat-back. For a subtle change, choose an axle-back.
Choosing the best exhaust for jeep gladiator is a personal decision. Consider your budget, sound preference, and how you use your truck.
