      Review & Installation Video

      Hey, guys, Stephanie from And today, we're gonna be taking a look at the X-Force Electronic Exhaust Cutout Kit in 2.5 inches for all 1979 and newer Mustangs. This is a universal kit that you can place anywhere you see fit in your 2.5-inch diameter exhaust. It's gonna be for the Mustang owners out there that would love to be able to change their exhaust tone on the fly and go from a normal sound to a much louder one in just a few seconds. This kit uses an electronic butterfly on a switch to bypass your mufflers and cats, depending on where you install this, and create a wide-open exhaust and then switch back whenever you want to. The kit costs about $200 and the install will be a three out of three wrenches on the difficulty meter.So this kit has a few different pieces. You only get one Y with the kit, so just keep that in mind. You get all of your electronic components, and the system even has a self-cleaning flange to help with exhaust residue buildup. You can always pick up another kit if you wanted to have dual cutouts, and keep in mind that this is made to work with 2.5-inch diameter piping. X-Force does make another kit that's for a 3-inch exhaust, so if you have a plan on upgrading to 3-inch, you'll want to check that kit out.This is a universal kit, so it can really be installed anywhere in your exhaust that you want. You can make it so that it'll bypass your mufflers or bypass both mufflers and cats. Of course, every car will be different, and where you put this does depend on your exhaust setup. You want to make sure that it won't be making contact with the underside of the car, other exhaust components, and that it's away from anything that hot exhaust should not to be near.X-Force has been making variable exhausts for quite some time now, so you can only guess that they have everything down to a science at this point. They make full variable cat-back and axle-backs that are able to change sounds on the fly using the same key fob that comes in this kit. The kit is made to fit nicely and avoid having any exhaust leaks. The electronics are very similar to their axle-back and cat-back technology. We've got the Y-pipe and the cutout, but we're also looking at a wiring harness for you to wire in your switch through the cabin so you can activate the cutout from the driver's seat as you please. Of course, you'll need to cut your exhaust in order to install this kit. For that reason, we're gonna call this install a three out of three wrenches on the difficulty meter. You also need some basic wiring skills in order to wire up the cutout to the switch.As always, you guys can check this kit out more online right here at

        Had them welded in by performance muffler but they did not do the wiring. heads up if you do not wire them right away there they raddled like crazy cause theirs no power. once i put power to them oh boy it sounds awesome and the raddle goes away.

        Amazing product

        Really changes the sound of your car with the click of a button. If you want to use 2 of them you have to purchase a dual harness which plugs into both cut outs. Sounds amazing. Snap crackles and pops.

        Almost perfect

        I was wondering why it didn't come with two, so I bought one. It turns out the best way this will fit is on the driver side right before the cat with the flat part facing the floor. If installed on the passenger side, it only fits in the same location, but with the round part facing the floor it increases the chance of the part hitting the floor. In the end making this an only right sided part. Need to look for a different part if installed on the left side so it can fit better. Also, once I installed this part, since there was an increase in air flow, less back pressure, it did feel like I lost some HP. Car is still fast, but now it is really loud which is what I wanted. It is also a relief that I can quiet the car whenever I want.

      5 Top Rated Questions

      So if i want 2 cut outs do i order 2 kits and get 4 remotes? Also would these bolt onto the 14 v6 pipes?

      • The X-Force Electronic Exhaust Cutout Kit comes with one cutout, so two kits would be required to do both pipes. This will share the same 2.5" exhaust diameter as your stock exhaust, so you will have no issues clamping these into your exhaust once you cut out a section for them to install.

      Helpful (6)

      Can one remote be programmed to control two cutouts? Obviously you'll need two cutout kits, but needing to click two buttons to shut down 'Merica coming out the pipes is a bit tedious.

      • At this time we are unaware of a way to program 2 cutouts with one remote for the X-Force Electronic Exhaust Cutout Kit.

      Could you use this to make an alternate route for bypassing your cats when you wanted?

      • You could use this to bypass the cats yes.

      Does this cutout get installed in front of or behind the catalytic converter, along the exhaust path?

      • The X-Force Electronic Exhaust Cutout Kit is a universal fit part, and can be installed anywhere in your exhaust where there is adequate room.
