You can remove the exhaust system from your Jeep Grand Cherokee yourself. The exhaust system is a pipe that allows the air from the engine to exit out the rear of the vehicle. The air passes through a catalytic converter to eliminate the harmful byproducts of the engine. It also passes through the muffler, which eliminates engine noise. The exhaust may need to be removed for a variety of reasons, and you can complete the process in about an hour.
Locate the exhaust under the vehicle along the passenger's side.
Loosen and remove the bolts on the exhaust flange directly behind the muffler with a ratchet and socket. The muffler is the round section that is mounted in-line with the exhaust pipe.
Unscrew the bolts on the flange at the muffler and the down-pipe with the ratchet and socket.
Remove the bolts that secure the down-pipe to the headers with the ratchet and socket. The headers branch apart to attach to each cylinder on the engine block.
Lubricate the stock rubber isolators with lubricating fluid.
Remove the exhaust system by pulling the metal bars from the stock rubber isolators. Continue until the tailpipe, muffler, catalytic converter and down-pipe have been removed.
