By Bill Tumas: For many Mustang owners a high-performance exhaust system is the first modification on the list. Besides the obvious performance gains, for many it's about getting that Mustang sound just right. What constitutes "just right" can be very subjective. Many of our customers agree, if you have a 2011-2014 Mustang the Roush Cat-Back is one of the best sounding systems out there. Today we are going to install this system on this 2011 Mustang GT.

The Roush system is completely made out of 409 stainless steel, includes these chrome rolled tips, and comes in an attractive price as well. All the hardware necessary for installation is included. The system is going to give you a nice, aggressive tone and a wide-open and throttle, yet have a nice non-droning sound for normal driving. For this installation you need jack and jack stands or lift, a 3/8 ratchet of impact gun, half-inch deep socket, 15-millimeter deep socket, flat-blade screwdriver, pry bar and safety glasses.

Once you get the back end of your car off the ground, the first step is to remove the factory mufflers. We're going to start by disconnecting the clamps located right here. All this can be done with hand tools, but we're going to use our cordless impact. We're going to remove the passenger side. At this point there is two ways you can get the mufflers off. You can remove the hanger bolts themselves and pull the whole assembly out, or you can unbolt these intermediate pipes, separate the two and then pull the muffler off. We're going to pull the intermediate pipes. Now we are going to separate the intermediate pipe. Now we are going to slide the muffler off the rear hanger. We're going to slide it back off the rear mounts. Now remove the other side in the exact same way.

Now we will install our new mufflers. Make sure you install them with the pipe going towards the inside of the car, hangers going towards the back. Now we will install on the rear hanger. Now we are ready to rehang the intermediate pipe. Let's start by putting the supplied clamp up into place. Now we'll put the intermediate pipe back on. It's a lot easier to put the clamp onto the intermediate and slide it up into place. Now we will line the intermediate up with our new Roush exhaust, clamp over, and tighten it down.

Now we will move on to the passenger side. Now I'll retighten the clamps from the intermediate to the H-pipe. We'll install the clamp onto the tip first, put the tip onto the muffler, and line it up, and then tighten it down. Now we'll install the passenger side in the same way. Line it up and then tighten it down. If you're finding your tip is too close to your valves like ours is here, then loosen the clamp that connects the muffler to the intermediate pipe and twist it outward for more clearance. Our installation is finished.

Our new exhaust looks great. We know most of you aren't buying it for looks, you're buying it for sound. Let's get it outside and see how it sounds. The Roush exhaust gave us a nice aggressive tone, still tame enough for daily driving. Installation should take you no more than an hour; you'll be back on the road in no time.
