This MagnaFlow exhaust system is made of 100% stainless steel and will fit your '67 through '70 Mustang. Includes a pair of these high-flow mufflers, their Tru-X X-Pipe, these mandrel-bent front tubes that will work with either a stock manifold or a long-tube header, pair of mandrel-bent tailpipes, a pair of polished stainless steel turndowns, and all the necessary hardware for installation.
This won't be one of our typical install videos. The MagnaFlow system is going to require welding to install properly. Since many of you probably don't have a welder at home, and will end up taking it to a local exhaust shop to have it installed, we're going to show you the basics of how it installs, and we'll show you how it sounds when we're finished.
Before we put the car up in the air, you want to remove your back seat. The reason you do this is so you can access your original hangers. It's not a bad idea to get some help when you put the new hangers on, you'll have to line it up to the floor.
Before you begin the actual installation, it's a good idea to lay all the parts out on the ground. That way, you get an idea of where everything's going to fit before you try to install it on your Mustang. You want to start by installing the isolator in the hanger onto the new mufflers. We're going to get a rough idea where those and the tailpipe go and hold them in place.
Put that over the axle. You can see the muffler, and I'm going to use the pole jack to hold it in place when you figure out exactly where you want to put our hanger. Then you want to mark the holes and take everything down. Sometimes you may get lucky and be able to use factory holes. Most times, you'll have to drill your own. I'm going to mark the top hole where we're going to drill.
Once you have it kind of roughly installed, to give you an idea on fit, you want to take the front pipe to get an idea of how they're going to fit. Basically, a universal pipe with a small bend in it, you'll want to see which angle is going to work best to get from the X-pipe to your header or exhaust manifold.
This is what it looks like once you have everything measured and cut to length. Now, you might be tempted to take this side and cut the exact same size for the passenger. You don't want to do that. You want to start again from scratch, just to make sure it's 100% accurate before you cut and weld.
Once you finish welding up your X-pipe and the rest of the mufflers and exhaust system exactly where you want them, we're going to put a small tack on each one of the fittings, just to make sure nothing moves around.
Now that our system's installed and everything's tacked into place, let's fire it up and see how it sounds. It sounds killer with our new engine. Just as we've come to expect from MagnaFlow's exhaust systems, it's the perfect aggressive sound we're looking for. This is not typically a do-it- yourself installation. Unless you're comfortable welding, you should just have your local exhaust shop handle it for you, and they'll have you back on the road in no time.
