This design allows for unrestricted exhaust flow, leading to a significant increase in engine output and a more pronounced exhaust note. The straight pipe setup maximizes the performance potential of the 4.0-liter engine.

Additional Considerations:
-
Professional Installation: While the installation process can be straightforward, professional installation is recommended to ensure precise fitment and optimal performance.
