    What’s up everybody? Landan with LMR.com! In this video I’ll be checking out MAC Performance’s cat back exhaust kit designed for the SN95 and New Edge Mustangs.

    MAC has been producing quality exhaust products for more than forty-five years. They are no strangers to quality and experience and this cat back exhaust kit proves just that!

    This cat back is manufactured from aluminized steel and the mandrel bent piping will measure in at two and a half inches.

    MAC engineered this cat back to feature their True Fit design which allows for multiple adjustment points. This will help out when installing the cat back and of course aid in properly aligning all of the piping.

    This system comes with MAC's multi passage design Flow Path mufflers for years of excellent sounding exhaust! The Flow Path mufflers have no packing material inside to burn up, so you will get the same sound as the first day it was installed.

    The cat back will exit to a nice pair of three inch or three and a half inch rolled stainless steel tips; both options are currently available, and in the box will be all needed piping, tips, and hardware for a straightforward installation.

    MAC designs this cat back exhaust to fit 1996 to 2004 Mustang GTs, 1996 to 1998 Cobras, and the 2003 to 2004 Mach 1. It will work with the factory mid-pipe or an aftermarket mid-pipe that features factory-like connections.

    When installing this cat back into your car, I would recommend the assistance from one of your friends. There are multiple pieces to this kit and having the helping hand will only benefit you throughout the entire install.

    Alright guys, now that I have the MAC cat back installed into this Mustang GT. Let’s check out some sound clips paired up with MAC’s pro chamber mid pipe.

    To begin the install, support the car via a lift or jack stands.

    Support the cat back approximately one foot from where it connects to the mid-pipe.

    Go ahead and support the mid-pipe as well.

    If you still have the factory exhaust on the car, use a Sawzall and cut the piping near the rear of the muffler.

    Loosen and remove the mid-pipe to cat back hardware.

    Use an exhaust hanger removal tool and remove the exhaust hangers.

    Remove the front section of the cat back from the car.

    Now, go ahead and remove the over the axle pipes from the car.

    Inspect each rubber hanger and replace if deteriorated.

    Place a provided washer over each of the provided bolts.

    Start with the first section of pipe and loosely tighten the hardware.

    Lubricate the rubber hanger and slide it onto the muffler hanger.

    Position the muffler section over the axle and slide the rubber hanger over the factory bracket.

    Loosely tighten the hardware.

    Next is the short pipe.

    Position it into place and loosely tighten the hardware.

    Depending on your model, slide the correct tail pipe rod into the tail pipe hanger.

    Lubricate the rubber to ease the installation.

    Slide one of the provided clamps over the tail pipe, and then slide the tail pipe over the short pipe.

    Push it forward until you have enough clearance to bring it back into the tail pipe hanger.

    Do the same for the other side.

    Now, progressively tighten all of the hardware working from the mid-pipe connections back.

    Make sure the exhaust is not touching the frame rails, control arms, rear brake lines, or gas tank.

    Ensure that the mid-pipe and cat back are even and slightly angled towards the bottom of the car for proper clearance.

    Align the tip and then tighten the Allen head set screw.

    Start the car and check for exhaust leaks.

    Double check your work, get the car on the ground and you’re all finished.
