Today we are going to be installing Magnaflow Performance Exhaust system part number 16641on a 2005 Infiniti G35 Coupe. Before we get started we want to go ahead and disconnect the negative terminal off the battery. The battery is located behind this panel here on the upper left-hand side of the engine compartment. This going to allow the computer to reset so when we get the new exhaust system on it will reconfigure itself to the new exhaust.
And we will go underneath the vehicle and start disconnecting the old exhaust. This is a Cat Back system so we will be moving the exhaust tips all the way up to the disconnect point behind the catalytic converter. So we need to unbolt the flange here from these two bolts and we are also going to need to remove the exhaust off all its hangers as well. The rubber hangers we are going to be using are located right here, right here, right here, and right here. Using a spray lubricant on the rubber hangers will make the removal of those a lot easier. You are going to want to save the rubber hangers because we will be reusing those for the re-installation.
And then also here just forward of the main exhaust you want to disconnect the ground wire off of the post here. We can go ahead and start disassembling it. I defiantly recommend spraying down all the bolts first with a lubricant like a WD40 because these will likely be rusted. This will help ease the removal of the nuts. Next we are going to go to the flange just rear of the exhaust and go ahead and remove the ground strap. Okay now we will remove the exhaust from all of the hangers. With all the rubber hangers removed you can go ahead and take the exhaust system out. The first piece we are going to go ahead and put in place is the one nearest the catalytic converter. Just going to be bolted to the flange, you want to make sure you have the gasket in place here. We do want to make sure the slight bend here goes toward the driver side. We want to leave everything fairly loose for the time being until we get it all installed and then we can tighten it all down.
Okay next we are going to put the second inlet piece in. You want the side with the rubber hanger to be facing the drivers side, it is going to attach right here. Then we are going to take one of the clamps that are provided with the installation kit and slide it over the inlet tube here over the end with the notches cut out of it. Go ahead and take that, and slide it over, slide it all the way in. All right go ahead and attach it to the rubber hanger here. Then we slide the clamp over and again we are just going to loosely install it for the time being. What I am going to do is manipulate it in and out of the inlet tube until that rubber hanger is facing straight up and down. Before I put the muffler on I am actually going to pre-install the clamp over this inlet tube because once the muffler is in place it is going to be tough to manipulate around there. Then we are going to go ahead and install the muffler itself. In preparation I went ahead and in the area where the muffler goes I went ahead and put all of the the rubber hangers back on the vehicle itself. Now that I have the muffler adjusted and properly into place I can go ahead and install our other clamp. I am going to go ahead and install with the threads on the upper side on each of them. And with that loosely installed I can go ahead and start tightening everything down. When tightening down you want to start with the forward most bolts and work your way rearward.
Last thing you want to do is go ahead and re-secure our grounding strap. To do that we are just going to be using the protruding threads from our clamp here at the rear most attaching point. Just slide that over and re-install it with the lock nut that is provided with the installation kit. With the grounding strap on again you just want to make sure all of our hangers are secure and our installation will be complete. This exhaust system was designed to make the car sound louder. Here is how it sounded before. And here is how it sounds now. And that will conclude the installation of part number 16641 on a 2005 Infiniti G35 Coupe.
