Installation Notes and Tips

Verify inlet and outlet location, diameter, and overall length before installation. This muffler uses a center inlet and right-center outlet configuration, so alignment with the existing exhaust path is important. Confirm the vehicle’s exact year break for 2000 Jeep Cherokee applications, since fitment is split by production date. Professional exhaust installation is recommended when replacing a welded or corroded factory muffler.
