An entry-level exhaust system that improves engine performance by boosting horsepower and torque. Its technologically advanced, Mandrel bent tubing and straight-through, satin muffler allow the exhaust to flow more freely through it.
Features:
Specs:
The cat-back system is the portion of the exhaust system from the outlet of the catalytic converter to the tailpipe. MagnaFlow systems have Mandrel bent tubes that allow for unrestricted airflow by maintaining the same diameter throughout every curve. This curvature leads to decreased back pressure.
MagnaFlow mufflers have a stainless steel perforated core that runs straight through the muffler, end to end, with no baffles, chambers or louvers that restrict airflow. This system's muffler sports a stainless, satin-polished finish. A layer of stainless steel wool insulates the perforated core to absorb noise, shield high exhaust temperatures and prevent blowouts.
Together, the Mandrel bent tubes and straight-through muffler increase horsepower, torque and fuel efficiency and decrease exhaust gas temperature. MagnaFlow's signature sound is deep and throaty on throttle but quiet inside vehicles. All materials are made with 100 percent stainless steel. Two-piece U-bolt clamps and hangers are included for installation. It includes a lifetime warranty.

Alright, today on this 2005 Chevy Silverado 3500 diesel we are going to install part number MF17931 from MagnaFlow. The first thing we are going to do is remove the bolts for the flange right here. I am going to spray them down with some lubricant first. And this is where the exhaust will begin. We will leave one nut on there to hold everything together until we are ready to completely take the exhaust down. Alright, now we will move on to the rubber hangers. And we will go ahead and apply some lubricant to them as well to help remove them. 1:00
Alright, before we take the last hanger off, we are actually going to wrap a strap around the exhaust to help control the descent when we take it off. Alright, now we have to take it out. You will definitely need an extra set of hands on this one. We will go ahead and start off by installing the front extension pipe. We will mount it to the OEM rubber insulator and then we will bolt it on to the 4 bolt flange. We will reuse the original OEM fasteners to reinstall. Go ahead and snug all of the bolts down just enough to keep everything together. Ok, next go ahead and slide on a clamp and install our mid pipe. And then we will slide that on to the first pipe. Slide it on as far as possible. We are going to leave everything loose for now. 2:01
Next we will go on to the muffler. We will slide on another clamp and then we will slide our muffler on. We are going to use this strap here to help hold up the muffler because it does not have its own hanger just yet. Alright, the rest of our tailpipe goes over the axle. We will install that on to the muffler. Alright, now we can add our clamp, slash hanger. Now we can slide our U-bolt into place and install our nuts. On our last part of tailpipe we will slide on a clamp on it. And then we will run everything together. Once you have everything roughly in the position you want it, we will go ahead and start tightening everything down. We will start from the front and work our way back. When we tighten it up one at a time, the whole assembly will fit to the vehicle. And of course, you will have to manipulate it as you tighten it down. Use a block of wood to give us adequate space between the exhaust tailpipe and the shock too. And you will probably end up having to loosen these and tighten them a few times to get the exhaust routed the way you want it. Once you have everything snugged down the way you want it, go ahead and torque everything down as specified in the instructions. Alright, once you have everything torqued down go ahead and rev the engine and check for an exhaust leak. And then make any adjustments as necessary after that. And there you have it for part number MF17931 from MagnaFlow.
