    Can I use these muffler for my vehicle 1994 mustang 5.0. I need to know. Thank you.

    • The MAC Pro Dump Cat-Back Exhaust was specifically designed for 1979-1993 five liter Mustangs only. The use of the exhaust on a 1994 was result in inadequate fitment.

    Do I need to still be running CAtalytic converters for this set up to bolt up correctly? Im running pypes headers, pypes downpipes, and a pypes off road x-pype. Will i be able to bolt these straight up tothe x-pipe with everything still lining up good?

      Great Sound

      Fit and finish are top notch. They are just the right volume, not too loud not too quiet, with a slight rasp. Very happy with product.

      Muscle car sound

      I have these on my 88 coupe. 306, TF heads, cam, Cobra upper/lower, shorty headers and off road x. I had Pypes catback before these and they sounded good but i wanted it to be louder. I've had Mac axlebacks on my 06 GT so I knew they would have a deep sound. They are loud! Great sound outside of the car, drone at lower rpms inside. Fit and finish is perfect. No problems with install. They tuck nicely under the car giving better ground clearance than the previous catback.

      Wow when you rev it!

      Really helped quite it down a tad from just have an h-pipe and no cats. But it sounds amazing and if you rev it since the pipe are towards the ground it will leave circles where u rev so in a gravel driveway it spread the grave a good 6in in diameter it's absolutely crazy.

      Well worth getting

      Good price. Easy fit. Exactly what I was looking for. I really do love these dumps. If your debating buying these, stop, they are worth it. Also, I love that EVERYTHING that I've ordered through a/m is arrives no later then 2 days after ordering. Awesome job a/m.

      MAC pro-dumps, stock 4-cat pipes.

      I'm writing this review because I didn't find many reviews from someone with the factory 4 cat h pipe. When I ordered it I was worried it would be too loud, but with stock cats it is not that loud at all. Idle is a low rumble with some volume to it. Drone is not bad unless going up a steep hill. Full throttle sounds good and not too loud. I wish it was a little louder at WOT, but for the price I'm not complaining. It gets 4 stars from me because the price is so low. If the price was higher it would be 3 stars. Also this fits fine on my '94 Mustang GT even though AM only lists it for '93 and under.

      Mac Pro dumps

      Took off my flomaster American thunder kit and installed these dumps. Way better sound. Deeper and more aggressive note. Mustangs, especially the 5.0 pushrod..... should have mac mufflers. Period..!! The
