The Jeep Cherokee XJ has earned a legendary status among off-road enthusiasts and daily drivers alike. Produced from 1984 to 2001, the XJ’s classic boxy design, durable drivetrain, and impressive off-road capability made it one of the most beloved SUVs in automotive history. One crucial yet often overlooked component of this vehicle is its tailpipe. The tailpipe plays a vital role in the overall exhaust system, and for owners seeking performance upgrades, emissions efficiency, or simply a better sound, understanding the tailpipe’s function and options is essential.
Understanding the Tailpipe on the Jeep Cherokee XJ
The tailpipe is the final section of the Jeep Cherokee XJ’s exhaust system. Its primary function is to release exhaust gases away from the vehicle, ensuring that harmful emissions are expelled safely. While it might seem like a simple metal tube, the tailpipe works in conjunction with the muffler, catalytic converter, and resonator to manage noise, control emissions, and enhance performance.
Tailpipe Location and Design
On the Jeep Cherokee XJ, the tailpipe exits at the rear of the vehicle, typically on the passenger side. The design is relatively straightforward: a bent steel tube that follows the contours of the undercarriage. However, various aftermarket modifications are available to improve durability and performance. Many replacement pipes are made from aluminized steel or stainless steel, which resist rust and corrosion much better than factory-installed components.
Common Tailpipe Issues in the Jeep Cherokee XJ
Over time, the tailpipe and exhaust system on an XJ can suffer from wear and tear, especially in regions with harsh winters or high humidity. Here are some common problems:
- Rust and Corrosion: Due to its position underneath the vehicle, the tailpipe is susceptible to moisture, salt, and debris. Rust can cause holes and weaken the pipe structure.
- Vibration or Rattling: If hangers or mounts break, the tailpipe can vibrate or rattle, creating annoying noises and risking damage to other components.
- Cracks or Leaks: Cracks in the tailpipe can result in exhaust leaks, potentially allowing harmful gases like carbon monoxide to enter the cabin.
Upgrading the Jeep Cherokee XJ Tailpipe
Many XJ owners choose to upgrade their tailpipes either to restore performance or to modify their vehicle for off-road use. Whether it’s for better sound, improved airflow, or aesthetic appeal, aftermarket tailpipes offer several benefits.
Benefits of Upgrading
- Improved Exhaust Flow: Larger diameter pipes or mandrel-bent designs allow exhaust gases to exit more efficiently, boosting horsepower.
- Enhanced Sound: Depending on the muffler and pipe combo, you can achieve a deeper, throatier exhaust tone.
- Long-Term Durability: Stainless steel or aluminized steel tailpipes resist corrosion and last much longer than OEM parts.
- Better Off-Road Clearance: Some upgrades include high-clearance tailpipe routing to avoid damage during trail rides.
Popular Aftermarket Options
There are many exhaust kits and individual tailpipe upgrades available for the Jeep Cherokee XJ. Some brands offer cat-back exhaust systems that include the tailpipe as part of a performance-enhancing package. Popular manufacturers include Flowmaster, Borla, MagnaFlow, and Dynomax. These systems often come with larger diameter pipes, mandrel bends for optimal flow, and corrosion-resistant finishes.
Installation Tips for a New Tailpipe
Replacing or upgrading the tailpipe on a Jeep Cherokee XJ is a manageable project for those with basic mechanical skills. However, some care should be taken to ensure a secure and leak-free fit.
Steps to Replace the Tailpipe
- Ensure the vehicle is safely lifted using jack stands or a lift.
- Use penetrating oil on all bolts and hangers to ease removal.
- Disconnect the tailpipe from the muffler using the appropriate tools.
- Carefully remove the old pipe, noting how it routes through the undercarriage.
- Fit the new tailpipe, ensuring all bends and flanges align correctly.
- Secure the pipe with new clamps or use welding for a permanent fix.
- Check all connections for leaks and ensure the pipe does not touch any part of the suspension or body.
For those unsure about the process, a qualified exhaust specialist or mechanic can install the tailpipe quickly and safely.
Legal and Environmental Considerations
While performance upgrades are popular, it’s important to stay compliant with local laws. The Jeep Cherokee XJ tailpipe, when modified, must still work with the catalytic converter and muffler to ensure emissions stay within legal limits. In some regions, loud exhaust systems or altered emissions equipment may be subject to fines or failed inspections.
Maintaining Emissions Compliance
To remain street legal, make sure that:
- The tailpipe is properly connected to a functional catalytic converter.
- There are no leaks allowing unfiltered exhaust to escape.
- The vehicle passes regular emissions tests as required by law.
Choosing the Right Tailpipe for Your Needs
When shopping for a new or replacement tailpipe for your Jeep Cherokee XJ, consider your primary goals. Are you looking for better performance? A louder or more refined sound? Increased durability for off-road use? Tailpipes come in various shapes and configurations, so selecting one that matches your driving style and local regulations is key.
Key Features to Look For
- Pipe Diameter: Larger pipes can increase flow but may reduce low-end torque if oversized.
- Material: Stainless steel is more expensive but offers superior longevity.
- Bend Type: Mandrel bends provide smoother airflow compared to crush bends.
- Fitment: Ensure the tailpipe is designed for the Cherokee XJ to avoid clearance or mounting issues.
The tailpipe on the Jeep Cherokee XJ may not be the flashiest part of the vehicle, but its role in the exhaust system is critical. Whether you’re maintaining your XJ for daily driving or preparing it for off-road adventures, a quality tailpipe ensures proper exhaust flow, improves performance, and maintains emissions compliance. With a wide range of aftermarket options available, there’s a solution to suit every need be it durability, sound, or style. By understanding the functions, features, and installation of the tailpipe, Jeep owners can keep their Cherokee XJ running strong for years to come.
