      Free Flowing Exhaust. Magnaflow delivers the ultimate exhaust for the 1987 to 1993 GT with this Street Cat-Back Exhaust. By reducing back pressure, this free flowing exhaust produces more power and torque where it belongs - at the rear wheels.

      Classic Muscle Car Sound. The Magnaflow Cat-Back Exhaust System includes a set of two Street Series Mufflers that feature a free-flowing, straight-through perforated stainless steel core, with stainless mesh wrap and acoustical fiber fill to deliver that smooth, deep muscle car tone.

      Quality Construction. Each piece is crafted from mandrel bent 2.5" stainless steel tubing for long life and a perfect fit. The system is completed off with brightly polished stainless steel turn-down tips, that exit in the stock location, giving a great finishing touch and a show quality look.

      Application. Made as a direct bolt on, this Magnaflow Street Cat-Back Exhaust will bolt straight up to the factory Mid Pipe without any modifications required on the 1987 to 1993 Mustangs to give it a deeper, classic sound.

        2 1989 GT - AntB Installation Time: Full Day

        Looks great but does not fit.

        Purchased this for my 89 gt. I wanted to get a bolt in kit so I did not have to take it to an exhaust shop. I have lift at my house, right away I could tell this is not going to work. With the new hangers provided the mufflers sat on a hard angle, hitting the floor. Took it to a shop they had to make all their own hangers. Could not even use the pipes in front of the muffler that should have attached to the cats. So in the end I’m out another $300 at the shop. I’m not the first to say they don’t fit. This should be addressed.

        The Magnaflow exhaust sounds great . Just the perfect rumble and not to loud in the car.With the convertible down and the pedal to the metal, its music to my ears.

        Great Exhaust

        I went with the Magnaflow system over Flow Master at the recommendation from a local speed shop that installed my 3.73 gears. The tone is much better to my liking over the all to common Flow Master sound. One word of caution, this kit come with new hangers, for just behind the mufflers, make sure you remove the old hanger hardware and use the kits. I tried with the stock hardware and could not get the system to line up properly. Once I ripped everything back out and used the proper hardware, the install went much easier. I could have saved myself 1/2 a day had I just gone with the new hanger hardware from the start.

        The tolerances are too close to keep them from rattling against the frame of the car. The routing could be improved to accomplish a more perfect fit.

        Great Exhaust!

        These exhaust pipes gave a great sound and look to my 5.0 and the amount of kick you get out of them is tremendous! Not obnoxiously loud, but it definitely turns heads when you pull away.
