Today on this 1991 Chevrolet S-10 we are going to be installing part number MF10784 and part number MF11226. This is going to be a little different from normal applications because we are actually doing a little bit of custom work. We are actually going to be removing the entire exhaust and replacing it with a MagnaFlow exhaust cut out and a MagnaFlow wide open muffler. The first steps we are going to show you is how to remove the complete exhaust and what we are going to have to do is remove it from the hangers and I will show you those locations right now. Before we remove everything we want to put a strap to hold up your exhaust so it does not fall when you are removing the bolts and mounts. 00:38
The first location we are actually going to remove is going to be the rear most bracket here. That is going to be these two bolts right here. We went ahead and sprayed them down with some lubricant to help get the bolts off since this is an older truck. The second exhaust mount that we are going to be removing is going to be the one at the back of the muffler which is going to be located here. It is also going to be two bolts holding it into the frame. After we remove the exhaust mounts your exhaust will be free hanging on that strap and then we are going to be removing these two bolts right here which will remove the exhaust from here back and then we will start applying our applications. 01:15
We are going to get started on removing the exhaust brackets. I just removed one, the other one was kind of rusted on there but we can actually just slide it back over. Then when we remove the exhaust this will just slide off so we do not need to take out this other bolt. So now we are going to remove the exhaust system. As you can see we are going to actually take the Sawzall off and cut it off right here. Since this is the factory exhaust it is all rusted up and there is no way we are going to be able to slide it off so we are just going to cut right at the edge where the old exhaust is going to be removed. As you can see we went ahead and put a second bearing strap so that when we finish cutting our exhaust over here that it will not fall. 01:57
As you can see we have it off now so we are just going to maneuver it around our rear end and slide it up over the top of it. It would probably be best to have a second set of hands to help you as well in maneuvering. On this exhaust cut out here they are provided with two band clamps but since we widened our diameter here they do not fit over the pipe any more so we went ahead and bought some after market pipe brackets. As you can see it just slides over like that and you will be provided those in your kit. On this application we are using these. We will put this on first and we will show you how to do that. Just take the exhaust cut out and just slide it over our existing pipe and then we are going to take our bracket and slide it up over it and then we can tighten it down on to our muffler to make it a good seal tight. 02:50
Now we are going to put our MagnaFlow exhaust in to place. You can put it whichever way you want that will best fit your needs. That is how you install this muffler and exhaust cut out here. The way we did it, we are actually going to need to make an exhaust hanger for it and you can probably just take your vehicle to any muffler shop and they can get one fabricated for you. It should not cost you that much. Now that we have it all installed we are going to show you a little bit of what it sounds like with the exhaust. Then we are going to remove the exhaust cut out and let you hear the sound of that as well. That concludes the installation for part numbers MF10784 and part number MF11226.
