In order to replace the exhaust Muffler with resonator, exhaust, and Tail Pipe on a 2.2l engine, first lift the vehicle and safely let it rest using the well-suited jack stand to support the exhaust resonator pipe. Pull off the insulators from the resonator pipe and from the Muffler. Cut forward of the weld at the Muffler inlet pipe by using an appropriate tool and then remove the Muffler from the vehicle. Subsequently, remove the resonator pipe nuts from the Catalytic Converter and pull out the resonator pipe and the gasket from the Catalytic Converter . It could be necessary to deburr the ends of the resonator pipe as well as the Muffler inlet pipe. For installation, be sure to put the new gasket on the resonator pipe and hook the resonator pipe to the catalytic convertor before tightening the resonator pipe nuts to 30 nm (22 lb ft). Attach the connect the resonator pipe to the insulators and mount the Muffler to the resonator pipe and to the insulators. Use the service clamp to attach the exhaust Muffler but then tighten the service clamp nuts to 45 nm (33 lb ft). Finally, take off support for the exhaust system, look for exhaust leaks and clearance underbody, and lift the vehicle.
