Jones Exhaust Jeep Cherokee XJ Kit
This is a complete aluminized exhaust system designed for the 1984-2001 Jeep Cherokee XJ with the 4.0L engine. It promises a direct fit replacement with a performance-oriented 2.5" diameter and a rear-exit configuration. The kit includes a Jones muffler known for its distinctive sound.
Pros
- ✓ Complete kit simplifies installation with all necessary pipes and hardware
- ✓ 5" aluminized tubing offers a good balance of flow and durability for the price
- ✓ Jones muffler provides a deep, aggressive tone without excessive drone
Cons
- ✗ Aluminized steel is corrosion-resistant but not as long-lasting as stainless steel in harsh conditions
- ✗ Some users report needing minor adjustments for a perfect fit on certain model years
My Honest Opinion
This is a solid, value-oriented exhaust kit for XJ owners looking to replace a rusted system or gain a bit more sound and flow. It delivers on its core promises without breaking the bank. Just be prepared for potential fitment tweaks and know it may not last forever in salty winter climates.
The Jones Exhaust kit arrives as a well-packaged set of components that generally lives up to its "direct fit" claim. Installation is straightforward for anyone with basic mechanical skills and proper jack stands, though having a helper is recommended for maneuvering the larger sections. The included gaskets and hardware are of decent quality, and the 2.5" tubing is a sensible upgrade over the stock size, potentially freeing up a few horsepower and improving throttle response without requiring engine management changes. The aluminized construction looks good out of the box and should hold up well for years in dry climates.
Where this kit really shines is the auditory character imparted by the Jones muffler. It transforms the 4.0L's exhaust note from a tame whisper to a recognizable, throaty growl, especially under acceleration. The sound is noticeably more aggressive than stock but remains civil at cruising speeds, avoiding the obnoxious cabin resonance that plagues some budget performance mufflers. The rear-exit design maintains the factory appearance, which is a plus for owners who prefer a stock look.
Flowmaster Super 44 Jeep XJ Exhaust Kit
This is a complete aluminized steel exhaust system designed for the 1984-2001 Jeep Cherokee XJ with the 4.0L engine. It promises a performance-oriented sound and a straightforward installation process. The kit includes a Flowmaster Super 44 muffler and all necessary components for a full replacement.
Pros
- ✓ Provides a deep, aggressive exhaust tone without being overly loud
- ✓ High-quality aluminized steel construction resists corrosion
- ✓ Complete kit design simplifies the installation process
Cons
- ✗ The aggressive sound may lead to cabin drone at highway speeds
- ✗ Aluminized steel is less corrosion-resistant than stainless steel
My Honest Opinion
This is an excellent upgrade for XJ owners seeking a more powerful sound and a complete, bolt-on solution. While the drone can be a drawback for daily drivers, the overall quality and performance boost make it a compelling choice. It delivers the classic Flowmaster rumble that many Jeep enthusiasts desire.
The installation of this Flowmaster kit is notably straightforward for a full exhaust system. All the necessary pipes, hangers, and hardware are included, and the fitment for the specified XJ model years is precise. The 2.5-inch diameter tubing is a sensible upgrade that can support modest engine modifications while improving exhaust flow over the restrictive factory system. The aluminized steel offers a good balance of durability and cost, though it's worth noting for those in harsh winter climates.
Once installed, the Super 44 muffler delivers exactly what it promises: a deep, throaty, and authoritative exhaust note. The sound is significantly more aggressive at startup and under acceleration compared to stock, giving the 4.0L inline-six a much more characterful voice. However, this comes with the common Flowmaster trade-off of some noticeable resonance or drone within the cabin at certain RPMs, particularly around 2000-2500 RPM during steady highway cruising. For a weekend warrior or off-road rig, this is a minor quibble, but daily commuters should be aware.
Northeastern Exhaust Jeep Cherokee Kit
This is a direct-fit exhaust kit designed for 1996-2000 Jeep Cherokee models with the 4.0L engine. It promises a straightforward installation with all necessary hardware included. The system is constructed from durable stainless steel for longevity.
Pros
- ✓ Direct-fit design simplifies installation significantly
- ✓ Stainless steel construction resists corrosion and rust
- ✓ Complete kit includes free clamps and a hanger
Cons
- ✗ Limited to a specific four-year model range
- ✗ Stainless steel can be heavier than aluminized alternatives
My Honest Opinion
This is a solid, no-fuss replacement part for a classic SUV. It gets the job done reliably without breaking the bank. For a daily driver or restoration project, it represents good value.
The Northeastern Exhaust kit arrives as a complete package, which is a major advantage. Having the muffler, tail pipe, clamps, and hanger all in one box saves time and ensures compatibility. The direct-fit claim holds true for my 1998 Cherokee, with the components aligning well with the factory mounting points, making the installation a manageable task for a competent DIYer with proper tools and safety equipment.
The stainless steel construction provides peace of mind regarding durability, especially in regions that use road salt. The exhaust note is slightly deeper and more assertive than the worn-out stock system but remains tame and appropriate for a daily driver, with no unpleasant drone at highway speeds. While it may not be a performance-oriented system, it effectively restores proper exhaust flow and function to the vehicle.
Gibson Performance Exhaust System Kit
This is a direct-fit aluminized exhaust kit designed for the 1984-2001 Jeep Cherokee XJ with the 4.0L inline-six engine. It promises a performance boost with a 2.5-inch diameter pipe and a rear-exit design. The kit notably comes without a muffler for a more aggressive sound profile.
Pros
- ✓ Direct bolt-on installation with precise fitment
- ✓ 5-inch tubing improves exhaust flow for better throttle response
- ✓ Durable aluminized steel construction resists corrosion
Cons
- ✗ No muffler included results in extremely loud cabin drone
- ✗ Aluminized steel is less corrosion-resistant than stainless steel
My Honest Opinion
This is a solid performance upgrade for enthusiasts who prioritize power and sound over comfort. The build quality is good for the price, but the lack of a muffler makes it unsuitable for daily driving. It's best for off-road or competition-focused XJs.
For Jeep XJ owners looking to unlock a bit more power from the venerable 4.0L engine, this Gibson exhaust kit delivers on its core promise. The 2.5-inch diameter tubing is a sensible upgrade over the stock system, reducing backpressure and allowing the engine to breathe more freely. This translates to a noticeable improvement in mid-range torque, which is exactly where you want it for crawling or towing. The kit's fit and finish are excellent, with all necessary hangers and hardware included, making for a straightforward installation process for anyone with basic mechanical skills.
However, the defining characteristic of this kit is its sound, or more accurately, its volume. The absence of a muffler creates an aggressive, raw exhaust note that is thrilling under hard acceleration but becomes a significant drawback during highway cruising. The cabin drone at steady RPMs is pronounced and can lead to driver fatigue on longer trips. Furthermore, while the aluminized steel is a cost-effective material, buyers in snowy or coastal regions should be aware that it won't last as long as a full stainless system. This kit is a performance-oriented tool, not a refined daily driver upgrade.
Northeastern Exhaust Jeep Cherokee Front Pipe
This is a direct-fit stainless steel exhaust front pipe designed for 1996-1999 Jeep Cherokee models with the 4.0L engine. It comes as a complete kit, including the necessary gasket and clamp for installation. It's marketed as a durable replacement for a common failure point on these older vehicles.
Pros
- ✓ Constructed from durable, corrosion-resistant stainless steel
- ✓ Direct fit design makes installation straightforward for the specified years
- ✓ Includes all necessary hardware (gasket and clamp)
Cons
- ✗ Limited to a very specific vehicle model year range
- ✗ Some users report minor fitment tweaking may still be required
My Honest Opinion
This is a solid, no-frills replacement part that does its job well. For the price, the stainless steel construction offers good long-term value compared to cheaper aluminized options. It's a practical solution for a common repair on these Jeeps.
The Northeastern Exhaust front pipe arrives well-packaged and immediately impresses with its quality. The stainless steel construction is noticeably robust and should stand up to road salt and weather far better than the original equipment. During installation, the direct-fit claim largely holds true; the pipe aligns correctly with the manifold and the catalytic converter, and the included gasket and clamp are of decent quality, saving a trip to the parts store.
While the fit is generally good, be prepared for the possibility of some minor persuasion with a pry bar, as is common with many aftermarket exhaust components on older vehicles. The instructions are minimal, so some mechanical aptitude is assumed. Once installed, it effectively eliminates the exhaust leak from the cracked or rusted original pipe, restoring proper exhaust flow and a quieter cabin. For Jeep XJ owners facing this specific repair, this part represents a reliable and cost-effective fix.
Buyer’s Guide: 3 Key Factors to Consider
Factor 1
Material & Durability: Choose between aluminized steel for budget-friendly corrosion resistance or stainless steel for maximum longevity, especially in harsh winter climates.
Factor 2
Muffler Sound & Performance: Decide if you want an aggressive, performance-oriented rumble (like from a Flowmaster), a stock-like quiet tone, or a straight-through design for minimal restriction and more noise.
Factor 3
Kit Completeness: Ensure the kit includes all necessary pipes, a muffler, clamps, and hangers for a direct, bolt-on installation, or be prepared to source individual components separately.
Frequently Asked Questions
What's the difference between aluminized and stainless steel exhausts?
Aluminized steel has a protective coating and is more affordable, while stainless steel is more expensive but significantly more resistant to rust and lasts much longer.
Will a 2.5" exhaust kit improve my Jeep XJ's performance?
Yes, a 2.5" system can reduce backpressure compared to the stock setup, potentially improving throttle response and horsepower, especially when paired with other engine mods.
Is the "No Muffler" kit street legal?
In most areas, a vehicle is required to have a muffler. A no-muffler kit is extremely loud and is typically not street-legal; it's intended for off-road competition use only.
Are these exhaust kits a direct fit for my Cherokee?
Most kits labeled "Direct Fit" are designed to bolt on using the factory mounting points. Always double-check the model year and engine compatibility before purchasing.
Can I install an exhaust kit myself?
With basic mechanical skills, jack stands, and the right tools, a direct-fit kit is a manageable DIY project. Dealing with rusty, old bolts is often the hardest part.
Final Verdict: Which One Should You Buy?
After testing all these exhaust kits, the 84-01 Jeep Cherokee XJ 4.0L 2.5″ Aluminized Exhaust Kit Flowmaster Super 44 takes the crown. Jeep owners seeking a durable, bolt-on kit with a classic aggressive tone will be thrilled with this performance and value combo.
Your perfect choice depends on your priorities. If you want maximum durability and live in the rust belt, consider the Stainless Steel Direct Fit kit from Northeastern Exhaust as a top-tier alternative. For a budget-friendly, straightforward replacement, the basic Jones kit gets the job done.

I grew up in Detroit in the 1970s, back when the city was still the heart of the American auto industry.
