We're going to show you a slightly different, yet very popular way, to add a little bit of rumble to your Fox Body Mustang.

Commonly also known as dumps, this is MagnaFlow's turn down style exhaust system fitting all 1986 through 2004 V8 Mustangs, there's a couple of reasons to go with a turndown. One of the more common ones is rear suspension. If you have an IRS swapped into your car, you have a large anti-roll bar, any kind of a drag bar on the back of it, an anti-roll bar, big sway bar, a lot of times, there's just not room for tailpipes. But obviously one of the most common reasons people go with this is the sound. A turndown system like this system from MagnaFlow is gonna be a nice, deep, rich, loud tone, which a lot of people like. The system, like all MagnaFlow, is full stainless steel, 2 1/2" pipes and gonna be a direct replacement for your factory cat back exhaust.

For this instillation, you'll need a lift or a jack and jack stands, 3/8 ratchet, 5/8 socket, 15 millimeter socket and an exhaust hanger removal tool.

Now our 1990 LX has obviously had several different aftermarket exhaust systems on it already. So what we're gonna do now is show you some quick stock footage of how to remove the stock style cat back. Then we'll begin the installation of our MagnaFlow turndowns.

Now if by some chance you still do have your factory exhaust on your car or perhaps you have the factory exhaust and somebody welded in a set of Flowmaster’s back in the day, what you'll have to do is cut right here to separate the tailpipe and remove the front section and back section. Like I said, our car has an aftermarket system, which has bolt on tailpipes. So we can separate them to remove the whole system.

Our Fox Body obviously has an aftermarket H pipe and honestly, who has a stock box body anyway? We're sure most of you guy have aftermarket pipes. But this offset is going to be the same, whether it's stock or original. What you want to do, we're gonna start with the mid-pipe, grab the longer one. It should go in the shorter offset side. Grab your original hardware.

Get it hand tight for now. You'll want it tight enough that it stays in place. But we want to make plenty of adjustments before we're finished.

All right. Now we're ready to grab our passenger side muffler. Now the passenger side muffler, this hanger here will be shorter. The driver's side one looks the same way. But this is about a solid inch longer. Put the shorter one for passenger side. Make sure you grab a clamp. Slide it over the mid-pipe and then up into the factory hanger. Now grab the rip and another clamp and just slide that on. Now this is gonna be really close to the rear axle. Obviously, our suspension's hanging right here. But basically, there's a lot of places to be legal. The exhaust has to exit at the rear axle or further back. So they have this dump out pretty much right at the rear axle to give you the best chance of being legal. Okay, with everything installed, now we can go back and tighten it up and make some adjustments.

Make sure you tighten these evenly.

Okay, then you want to repeat the process on the other side and the installations finished.

Now our MagnaFlow turndowns fit great, were easy to install. But now, let's hear how they sound.

Still one of my favorite sounding exhausts on a Mustang is a good set of turndowns. You get a nice, deep tone inside the car and they just sound really, really good, especially with a cam.

It might just be my personal opinion, but I've always loved the sound of a Fox Body with dumps. I mean, this thing sounds absolutely amazing, especially with a small cam in it. Now, as far as the installation goes, they're very easy to install. You have tons of room to work around there. You don't have to worry about lining up tailpipes. Again, a very simple installation, take you less than hour. You'll be back on the road in no time.
