      MAC long tube headers

      The product itself is very good quality, the install was not too hard but does require lifting the engine. The bolts that came with the headers to bolt to the mid pipe are standard while the nuts to go them are metric, not that big a deal, i had to go to the hardware store to get matching nuts and bolts and was a little disappointed with this issue. Overall great product.

      Great fit!

      These headers fit great, I was hesitant of using them after reading about fitment issues but I believe mac has fixed them! I installed them while dropping the motor in with the passenger side on and the driver's side header sitting in the compartment with the steering shaft going through. All went in easily even with the bell housing on. Also worked great with Gt40p heads. Be sure to pick up the matching midpipe, I don't believe the Bbk one will fit

      Amazing price for chrome!

      Looks great under the hood and was a automatic when I rebuilt my 5.0 to help get some of that built up air out of the engine, thanks American muscle! Always happy with the service !

      Mac LongTubes..

      these longtube headers were easy to install. i really like the way they look and they also came with all the hardware and the gaskets that they require. To install the headers you would have to -loosen the motor mounts -lift the motor up a little -remove passenger side motor mount -slide both headers in -put passenger motor mount back in -lower motor and the rest is a piece of cake. also will have to remove steering shaft and put back on after installing the headers also remove starter. but overall not much of a hassle to put on! can't beat the price

    Will these work on a 94 GT 5.0L with a 5-speed? I know they don't have the emissions garbage but that doesn't apply since I'm in a non emissions state and have done an EGR and Smog pump delete.

    • The MAC 1-5/8 inch Chrome Long Tube Headers are specifically designed for 79-93 5.0L 5-Speed Mustangs and will not fit other years or models.
