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 massive 3" diameter polished stainless steel tips for classic muscle car looks and sound.

        Install mac cat back exhaust

        Mac cat back sound really good. So I had BBK long tube header with BBK short x pipe and mac cat back exhaust so install was too bad drive side was pretty much easy than passages side because I had move or adjust muffle, tailpipe and tip chrome end too try get tailpipe in middle of between gas tank and tires so I had need hand with it. So I like it pretty much I can't wait for weather get warmer and beautiful outside to drive my mustang and listen to muffle see what sound like

        Mac exhaust

        Not as loud as flowmasters but a very nice sound. I like some features of flowmasters but these are a good value. Kit was very complete and went on with no hassles.

        Easy and sounds good!

        Bought this for my fathers GT convertible and he wanted something that had no freeway drone but still showed off that V8 growl. So far he’s had it on for a week and loving it. The hardest part was just aligning all the pieces to make the tips sit right but with two people it only took us about 2hrs to install in total.

        Great product, Sounds great matched with my Bassani xpipe. I recommend having a someone to help with installation, can be a little annoying at times lining things up by yourself. Other than that I highly recommend this Mac catback exhaust

        1995 Mustang GTS, H/C, Full exhaust

        Great sound, not as loud as my last Mac system but it's still brand new. Fit and finish is decent. My OCD had a hard time lining up the tips to make them true and square with one another as the axle humps seemed to be a little off but nothing two guys couldn't handle. Definitely will buy again if need be.

        5 1994 GT - Al

        MAC CAT-BACK 86-93/94-95 GT

        My 1994 GT Convertible exhaust set up: original manifolds (headers), Bassani catted x-pipe, original cat-back pipes with Flowmaster 40's welded. Tried other mufflers - Borla Pro XS, Dynomax Super Turbos - with the original pipes before installing the Flowmasters. They all sounded terrible, like an old pick up truck, and the drone from the Flowmasters was terrible. I think the exhaust was being choked from the x-pipe (2.5in) to the pipes(2.25in). I don't think it would have mattered what muffler I installed; it was going to sound bad. Did a lot of searching, listening, etc. Wanted to minimize drone and keep the sound somewhat tame. The rep for AMERICANMUSCLE recommended the MAC cat-back. Received it in 2 days. The 3in tail pipes look fantastic. The sound is better than I thought it would be. Drone is minimal. Does not give me a headache. Does not interfere with the radio, although you have to turn it up a notch. And, you can have a conversation at 70mph/2k rpms. At 65mph/1700rpm, you don't hear the mufflers. When you push the throttle through the gears, the 5.0 has an authoritative sound. I had it installed at a shop. Fit is perfect. For the money, there is no better exhaust note!
