Steps
Raise and support the vehicle
Let the exhaust cool completely. Raise the vehicle on a level surface and support it securely on jack stands before working underneath.
Disconnect the front exhaust section
Apply penetrant to the flange hardware. Mark the oxygen sensor position, unplug it if needed, and remove the front pipe flange and hanger fasteners while supporting the pipe.
Remove the mid-pipe and muffler
Support the mid-pipe before releasing its rubber hanger. Remove the flange nuts connecting it to the front section and muffler, then release the muffler hangers and lower the sections carefully.
Install the muffler
Seat the new muffler in its rubber hangers and align its flange. Clean the mating surfaces, install a new gasket, and start the fasteners by hand.
Install the mid-pipe and sensor
Fit the mid-pipe to the hanger and muffler with new gaskets. Reinstall the oxygen sensor using its marked orientation, keeping its wire clear of hot or moving parts.
Install the front pipe
Align the front pipe with the manifold and support brackets. Install new flange gaskets and start all fasteners by hand, then tighten connections evenly to the vehicle's specification.
Inspect exhaust alignment
Check that the pipes sit without contacting the body, suspension, or heat shields. Reconnect the oxygen sensor, lower the vehicle, and listen for leaks during a brief startup.
Check your vehicle’s repair manual for exact specifications and fit.
