Exhaust Pipe, Front

Service of the muffler and tailpipe begins by fitting the vehicle onto a hoist in the NEUTRAL position. Position the vehicle slip on a hoist into NEUTRAL while you use a suitable jackstand to stabilize muffler and tailpipe. After that loosen the Torca® clamp nut. Reinstall the clamp while tightening it to 55 Nm (41 lb-ft). For muffler and tailpipe removal the isolators need careful attention to prevent breakage; applying soapy water will help detach the three isolators and extract the muffler and tailpipe assembly from the vehicle. The installation process requires the return of removal steps while replacing gaskets and nuts along with inspections for replacements of any damaged isolators. The engine start-up should be followed by exhaust leak testing.

The first step to service the muffler and tailpipe involves hoisting the vehicle in the NEUTRAL gear. To install or uninstall the muffler and tailpipe a suitable jackstand should hold them before releasing the Torca® clamp nut which needs to be tightened to 48 Nm (35 lb-ft) final torque value. Soapy water serves to release the three isolators without tearing so you can carefully detach the muffler from the tailpipe unit. A mechanic's wire should support the intermediate pipe to avoid flexible pipe damage. Reinstallation procedure starts with reverting the removal steps and using new gaskets while tightening nuts to specification and checking all isolators for damage prior to replacement. After starting the engine run the car to verify there are no exhaust leaks.

The first step for servicing the exhaust intermediate pipe starts by setting the vehicle on a hoist with neutral transmission. When servicing the intermediate exhaust pipe start by taking out the two exhaust Y-pipe flange nuts and disposal of the gasket. Follow the installation procedure and achieve adequate torque of 40 Nm (30 lb-ft) on the flange nuts. After loosening the Torca® clamp nut the reinstall procedure requires its tightening to 48 Nm (35 lb-ft). Before removing the exhaust intermediate pipe you must detach it from both the muffler and tailpipe. The installation process requires using new gaskets and exhaust fasteners while performing the reversal of removal steps. Begin engine operation to verify exhaust leaks exist or not.

The repair of the exhaust crossover pipe begins with placing the parked vehicle into NEUTRAL on a hoist. A technician needs to take out the exhaust Y-pipe and discard all four nuts and gaskets which connect to the left-hand and right-hand catalytic converters. Replacement should include new fasteners and gaskets which need tightening to 40 Nm (30 lb-ft). The service process begins with discarding the exhaust Y-pipe flange nuts before removing the exhaust Y-pipe together with its gasket. The installation should begin by reversing the removal steps including replacement of new gaskets and nuts before applying torque at 40 Nm (30 lb-ft). The final step becomes starting the engine then inspecting the exhaust system for leakages.
