MagnaFlow Exhaust System Installation - 2009 Chevrolet Silverado 1500 Series - etrailer.com

Refer to manufacturer installation instructions and specs for complete information. Today on this 2009 Chevrolet Silverado 1500 Series extended cab short bed we are going to be installing MagnaFlow Exhaust system part number MF16568. We are underneath the vehicle and the first thing I have done is lowered the spare tire out of the way to give us some extra working room. We also want to disconnect the battery. What that is going to do is once we get the system installed we can reconnect it and it will actually reset the computer system so it does not bring up any trouble codes from the new system. The first step before we can install our Exhaust system is to of course remove the factory installed Exhaust. There are four Exhaust hangers that we are going to need to remove the Exhaust off of towards the more rear side of the Exhaust system. 00:39 To the catalytic converter there is a clamp attaching the Exhaust to the converter. We are going to need to loosen that clamp as well. That clamp is going to be reused so we do not want to damage it so set it off to the side. Also to ease in the removal of the factory installed system we are going to need to cut the pipe just rear of the muffler right before the main bend right above the axle. Cut somewhere right in here, that will allow us to take that piece off and then remove the forward section all in one piece. With the cut made and the rear tail pipe removed I am going to go up to the forward side and remove my clamp next. With the clamp loosened up go back through and remove the main Exhaust system off its other three hangers. 01:44 Now it is time to start installing our new system. We are going to start with the inlet tube into the catalytic converter and again we are going to be reusing the clamp that we removed in the previous step. You will notice there is a bend in the inlet tube coming over the cross member. Make sure the bend is going up. We do not want to fully clamp it down just yet. We want to wait until we get all of the pieces in position and then we will come back through and tighten everything down. We are going to tighten it up to hold it into place. Next we are going to put the muffler in to position. We are going to merge the two pieces together using the three inch clamp and it is going to merge up with the factory hanger. Then you need to attach it to the two factory hangers. We are going to start installing back to the tips. This model only had single Exhaust on it but we are putting a dual Exhaust system on it. So we are going to finish out on the passenger side where the factory pipe was and then we will come back through and finish off the driver side. 02:52
