Back in the late 90’s when I bought my ‘87gt, the exhaust was one of the first performance mods I did. After the subframe connectors. The owner of the speed shop I went to sold me on MAC. Got a ProChamber H-pipe and then MAC all the way back. I didn’t know any better at the time, it was my first fox body. He said the MAC didn’t have that dreaded ‘drone’ like the Flowmasters, and in their Dyno experience, actually made a few more horses. I took his advice. I love it. It’s the same exact set up I am still running all these years later. Classic Fox Body sound I fell in love with in high school back in the late 80’s. Great sound, good power, no drone, and looks as good as it did when installed. Of course the car was never my daily so it’s never seen rain, snow etc.
