How to Change a Jeep Wrangler Exhaust

The exhaust system on your Jeep Wrangler can be replaced to increase the power, fuel economy and performance of your vehicle. Stock exhaust systems do not allow the air to flow from the engine as efficiently as some aftermarket products, creating high exhaust temperatures and decreasing the vehicles power and fuel economy. Replacement exhaust kits may be purchased on-line or at your local auto parts store and installing the new exhaust requires only a ratchet and socket set.

Loosen and remove the clamps that connect the muffler to the exhaust tailpipe with a ratchet and socket.

Lubricate the rubber isolators at the frame by spraying them with lubricating fluid.
