      Description

      Aggressive Throaty Sound. Add a throaty muscle car exhaust note to your 5.0L GT and improve the exhaust flow at the same time with a MAC Performance Cat-Back exhaust system from AmericanMuscle.

      Flow Path Mufflers. MAC Flow Path Chambered Mufflers feature a patented multi passage design, following Helmholtz's Theory of Tone, to produce a muffler that effectively flows exiting exhaust gases all while maintaining a desirable tone. With no packing that can burn out, Flow Path Mufflers will sound the same mile after mile, year after year.

      High Quality Construction. Mandrel bent from durable 2.5" aluminized steel tubing for strength and corrosion resistance, this MAC Performance Cat-Back features two "Flow Path" chambered mufflers with turn down tips to match the original factory GT appearance.

      Application. This MAC Performance Cat-Back exhaust system is specifically designed to fit the 1987-1993 5.0L GT Mustangs.

        Poor fitting!!!

        Exhaust sounds good but the tailpipes hit in the rear on the control arms!! Wanted the dumps but they where out of stock. Didn’t have all of the hardest with it as well. Had to reuse some of my old stuff!

        Settling in...

        Install was a little tricky. Nothing indicates if two mid-pipes must go on certain sides, and no directions. They appear to be same shape. Take your time making sure the system clear all objects. Going from stock 2.25" to 2.5" makes spacing tighter. End tips did not turn out even on both sides, and mufflers ended up slightly cocked. Be prepared for the drone sound for long trips, even in 5th gear.

        install

        I installed the cat back on my 89 gt . It was easy for the most part but it would of gone faster if there were instructions from the manufacture or even the pipes are marked for which side. The only thing that i notice is from the mid pipe to mufflers the bolts were hard tighten with a socket driver, if they were going the other direction it would help. Beside that I very pleased with install and sound.

        MAC RULES

        I loved the FlowMaster American Thunder until I bolted in the MAC. My car makes 302rwhp/328rwtq with a lumpy cam. Sounds nasty at idle and awesome at WOT. The exhaust is well designed with ball fittings. It fit like a glove even with 275/40's on 10 inch wheels. They take the time to even brush rust inhibitor on the welds. MAC knows the 5.0. The FlowMaster is a great choice but the MAC fits so much better and sounds way better at idle. MAC #1!!

        5 1992 GT - FOXROD

        MAC Flowpath Exhaust

        Installed on 92 GT along with a MAC H-Pipe. Removed complete factory system. Loved the ball and socket connections which allow great adjustability and ease to remove when necessary. Mufflers tucked up nice and high and aligned with hangers perfectly. Sound - slightly deeper at idle " quieter then Flowmasters I have used" and come alive at wide open throttle, similar to Fowmaster Force Ii system. Love it, not to abnoxius but aggressive under full throttle.
