Roush completely redesigned their Extreme Axle-Back for maximum performance and a more aggressive growl! The Extreme axle-back exhaust from Roush uses 409 aluminized stainless steel for durability and corrosion resistance. With a full mandrel bent construction that extends from the axle to the 4 inch chrome 304 stainless steel dual wall tips for minimal flow restriction. Roush also took inspiration from their 2015 Mustang exhaust systems when they designed this axle-back for your 2005-2010 Mustang GT or 2007-2010 Shelby GT500.
The straight through design is less restrictive and gives this exhaust a tough, guttural sound unique to Roush exhausts. Although the extreme sound of this axle-back may not be for everyone, it’s by far one of the best sounding stand-alone axle-back exhaust on the market today. And at a price that will easily allow everyone to know you are driving something special.

Intermediate skill is required for this installation.
The Roush Extreme axle back is made of 409 aluminized stainless steel and features four inch chrome tips. This is about as close to a muffler delete as your going to get. Roush uses resonators with a straight through design to give you most aggressive sound possible. For this installation you need a lift or a jack and jack stands, half-inch ratchet, fourteen millimeter socket, fifteen millimeter socket, flat blade screwdriver, hammer or mallet, and safety glasses. Even though this car already has an aftermarket axle back, the removal is going to be the same if you have a factory.
Disconnect the two pipes back here from the tailpipe of the axle back, then disconnect the two up front from the tail pipes to your factory H-pipe. Bend up this little tab on the other side so it can come clear. Move the screwdriver to separate the clamp a little bit, and we'll tap it backwards. Since we want to release the clamp back there, just work the pipe out of it. Now we'll slide the muffler off the factory hangers and remove it. Then go ahead and repeat the process on the other side. Now we'll slide one of the clamps over our Roush Extreme resonator, put it up in the factory hangers. Now grab our stock tail pipe, put it back over the rear axle, connect it to our Roush Extreme. Now we'll hammer the sleeve back over in the front here. I'm going to snug down the front bolts. Don't tighten them all the way, just snug them. Now we'll grab the tip and put it up into place. Get it lined up where we want it and tighten it down. Repeat the process on the other side.
Now let's fire it up and hear how it sounds. Definitely very loud, crackly, aggressive sounding, especially with the stock cat still on the car. Actually, having driven it three-valve for a while, I almost forgot how they sounded. These engines still have a nice good sound to them. One of the nice things with the three-valve or any of the, I'd say, pre-2015 cars for that matter, as long as they leave the cats on, they're not loud inside at all. I can hear the exhaust in this car, but it's definitely not overwhelming, even though I know how loud it is outside. I know people are always concerned about drone with these systems. We're going to go up to highway speeds, around that two thousand RPM threshold, and see what it sounds like. That's sixty-five, two grand. You can hear it, but it doesn't have that drone-y sound to it. It just sounds like a nice healthy exhaust. I'll get on it a little bit. Even wide open throttle, inside the car it's not that loud at all. It's actually got a pretty nice tone to it, too. I thought it would be a lot raspier inside, but it really isn't. Given the loud, aggressive sound outside, it's perfectly livable inside.
The name Extreme was the right choice for this Roush axle back. If your looking for something that's loud, aggressive, in your face, it's a perfect choice. While it's not for everybody, this is the sound your looking for, I would definitely check it out. Installation's pretty straightforward, because the fit and finish is top-notch like always. It will only take you around an hour to put on; you'll be back on the road in no time.
