- Better Sound: Many enthusiasts appreciate the deeper, more aggressive sound that aftermarket headers provide.
- Weight Savings: Some headers are lighter than factory manifolds, which can contribute to overall vehicle performance.
Power Gains
When considering aftermarket headers for the XJ Cherokee, it’s essential to understand the potential power gains. On average, you can expect:
- 5-15% increase in horsepower depending on the header design and other modifications.
- Increased torque in the mid-range RPMs, making the vehicle feel more responsive.
- Improved throttle response due to better exhaust flow.
Installation Tips
Installing aftermarket headers on your XJ Cherokee can be a rewarding project. However, it requires careful planning and execution. Here are some tips to help you through the process:
