2006 Buick Rainier Muffler Parts and Q&A

• Q: How to replace the muffler on 2006 Buick Rainier?

  A: First you must lift off and support the automobile properly before lifting. It is important not to reuse any components that have been oxidized, damaged, or in any way compromised. For the vehicle with the ll8 engine, purchase the resonator and Tail Pipe because they are likely to be replaced together, typically fixed using a clamp. Check the exhaust system parts for reusability. Pull out and remove the nuts on the left and right sides that hold the support that the Muffler is connected to the Catalytic Converter pipe. Isolate the Muffler and tailpipe assembly from the hanger insulators and lower the assembly. Support the exhaust system then cut the Exhaust Pipe at the line designated and take away the Muffler from the pipe in the tail. For installation, connect the new Muffler to the tailpipe and fasten it to hanger insulators. Mount the Muffler to the Catalytic Converter and tighten the nuts to 45 nm (33 ft. Lbs.). Loosely put in the clamp in order to hold the Muffler onto the tailpipe, align the tailpipe properly and tighten the clamp nuts with a torque of 50 nm (37 ft. Lbs). Lastly, check for leaks in the exhaust system and for underbody contact, replace the frame brace and lower the vehicle.
