• Q: How to replace the muffler on the NB5-Single Exhaust on 2008 GMC Acadia?

  A: The first step to change the Muffler on nb5-single exhaust involves lifting and supporting your vehicle. Detach the exhaust flexible pipe from its connection to Muffler nuts. You should work with assistance to detach the rubber insulators from exhaust underbody hangers before extracting the Muffler assembly from the exhaust flexible pipe and vehicle. With help you should first mount the Muffler assembly to the vehicle followed by mounting the exhaust flexible pipe before installing the rubber insulators to the exhaust underbody hangers. Adjust the exhaust flexible pipe to Muffler nuts to a torque of 50 n.m (37 lb ft) before allowing the vehicle to lower down.
