Removing the stock exhaust system will allow you to replace it with a new system or upgrade it with an aftermarket system. If your exhaust system has damage to it, replacement pieces are available from most auto-parts stores but replacement of the entire system with a more free-flowing, larger-diameter exhaust system can increase the performance and fuel economy of your Dodge truck. Another option is to replace the system from the catalytic converter to the back if you prefer.
Things You'll Need
- Jack stands
- Socket set
Raise the rear of your Dodge truck with a jack and support it under the rear axle with a set of jack stands positioned under the rear frame rails. Move your jack to the front of the truck and raise it as well, placing a second set of jack stands under the frame rails in the front. Make sure the truck is very stable before working under it.
Position yourself under the rear of the truck and remove the tailpipe section first. Remove the exhaust clamp from the pipe between the tailpipe and the muffler, using a socket and ratchet. Slide the tailpipe hanger out of the rubber isolator on the frame and remove the tailpipe from under the truck.
Move forward to the front of the muffler and remove the exhaust clamp with a socket and ratchet. Slide the muffler forward to remove the two rod hangers from the rubber isolators on the frame. Lower the muffler down and remove it from under the truck.
Move forward to the front exhaust pipe and catalytic converter. Locate the retaining bolts where the front pipe and the exhaust manifold meet. There are two on each side. Remove the retaining bolts using a socket and ratchet.
Pull the pipe down and slide the mounting rod on the catalytic converter out of the rubber isolator on the frame, then remove the pipe and converter as a unit. Slide the assembly out from under the truck.
