      Review & Installation Video

      What's going on guys? I'm Alex from And today, I'm bringing you my very quick review and breakdown of the Blowfish Sound Tube Delete Kit fitting your 2015 through current Mustang GT. So in this video, I'm gonna give a very quick overview of who this kit might appeal to, why you might wanna install this, what you should expect to be spending, and then what it's gonna take to get this installed on your GT. We're gonna be looking at a pretty easy one out of three wrenches in the difficulty meter and less than 30 minutes to get this onto your car. And I'll have a little bit more detail for you on that later.So if you've been around the block, either in or out of the aftermarket car community, you've probably heard at one point or another that most, if not all, cars, including the 2015 through a current Mustang, have been equipped with something called a sound tube. Now, that's gonna be something which essentially pipes more noise into your cabin to give you a little bit more of an engine sound.Now, the sound tube itself is a pretty unnecessarily large apparatus, for lack of a better term, and it's honestly about probably this big. And given that it's just added weight, its purpose, again, is essentially to pipe in more intake resonance directly into your cabin to give you a little bit more of a engine sound. But, in my personal opinion, I think it's pretty on the artificial side, and it's just something that you really don't need in your car.So if you've been in somebody else's Mustang that did have this mod installed, there's probably a decent chance you heard a little bit of a change in tonality here. But having been in a few GTs myself with this mod installed, I've gotta tell you it's a little bit on the minimal side. But something that I did personally notice is that if you're to install a throttle body intake manifold or a cold air intake on a car that does have the sound tube installed, it's essentially gonna be watering down that sound from your engine bay.Now on the flip side, if you were to have this installed with the aforementioned modifications, the sound that you would be hearing from under the hood would be that much greater. So you're essentially gonna be hearing a lot much more air traveling around, lot much more sucking when you're on and off the gas. So by installing this Sound Tube Delete Kit from Blowfish, I will go on record and say that this is gonna be more of a tonality change. This isn't gonna be like something where you're gutting your cats or you're installing an axle back exhaust where, as soon as you fire up your car, it's gonna be apparent.Again, if you're gonna throw this in and you're gonna install a cold air intake and a throttle body down the road, you're gonna get much more engine noise being incorporated into your cabin. Whereas if you were to leave your factory sound tube installed, you'd be getting a little bit more slop getting piped into the cabin, which, again, I think is a little bit more on the artificial sounding side and just fake.So one last thing I definitely like about this kit, or at least the removal of the factory sound tube, is that, again, it's gonna be pretty unnecessarily long. When you pull this out of your engine bay, you're probably gonna think to yourself, "Why was this even installed in the factory?" Which, again, was just to give somebody a little bit more noise in the cabin. But, by removing this, it's gonna clean up your engine bay pretty nicely, in my opinion. And, again, you're only gonna be looking at an addition of about maybe one to two pounds of added weight.Now a quick little feature that Blowfish likes to call out here is that in the event you're gonna be installing a new head unit down the road or if you're just gonna be swapping in something else, you can easily drill right through here, so you can run your wires right through your firewall. So in terms of the pricing here, guys, you're looking at 10 bucks for this kit, which is really just a no-brainer for me. You're looking for a really quick-to-install modification over the weekend or some day after work, you just want a wrench on your car, it's gonna be a great option for you.I do wanna say, in comparison to some of the other options out there, you're gonna see that they do have a tendency to get up there in price, which I personally think that the Blowfish option is gonna be that much better, as there's really no need to spend that much more on something where it's literally just gonna be the leading that sound tube.All right, guys. So switching gears to the installation portion of the video, just like I had said up top, you're looking at a pretty straightforward one out of three wrenches in the difficulty meter and about 15 to 30 minutes to remove your factory sound tube and plug that into this unit right here.Now, while I will usually say that most, if not all, of the modifications that we've installed here are pretty easy, one thing that I will definitely throw out there is that if you've got a friend or maybe a child that's got small hands, definitely rope them in to help you get the factory sound tube removed, as you're gonna be thanking yourself later at the end of the day.So the easy install here is definitely a huge selling point for me, aside from needing some small hands to pull the factory kit. You're gonna wanna start by accessing the tube down by your throttle body and then essentially working your way up the dripper side of your valve covers to the firewall. You're essentially gonna need to pull the tube a couple clamps and then chase it back to the firewall and then move back to the front of the vehicle where you're essentially gonna plug this, and you're good to go.And honestly, it doesn't get any easier than that. And while I know it's much easier said than done, you're looking at about 15 to 30 minutes before you complete it here. All right, guys. So just to wrap things up here, some final thoughts, if you're the 2015 through current S550 GT owner, you're not only looking to clean up your engine bay and remove that obnoxious looking sound tube, but you're looking to get away from having some of that artificial noise piped into your cabin, I would definitely check out this option from Blowfish for your GT. So that's my quick review and breakdown of the Blowfish Sound Tube Delete Kit fitting your 2015 through current Mustang GT, available right here at

      Features, Description, Reviews, Q&A, Specs & Installation


      • Deletes Factory Sound Tube
      • Prevents Odors from Entering Cabin
      • Includes Rubber Intake Cap, Clamp and Firewall Plug
      • Fits All 2015-2020 GT Mustangs


      Blowfish Racing Sound Tube Delete. For some odd reason Ford installed a sound tube on their GT Mustangs. The idea behind the sound tube is that it's supposed to pipe engine noise into the cabin of the Mustang to enhance the driving experience. Well, true motor heads find this idea lame and want it gone. That's why Blowfish Racing came up with the Sound Tube Delete Kit.

      Complete Kit. The Blowfish Racing Kit deletes the sound tube entirely. The kit includes a block off cap for use on the factory intake and a firewall plug to prevent debris and odors from entering the cabin. There are no permanent modifications required making this kit totally reversible for those looking to go back to stock at a later date.

      Application. This Blowfish Racing Sound Tube Delete Kit is specifically designed for use on 2015 to 2020 GT Mustangs equipped with the 5.0L Coyote V8 engine.

        Awesome if you hate that stupid tube

        If you have a stock airbox and it isn't already deleted from an aftermarket CAI, this is a very good cheap purchase. I can say that my cabin is much quieter after the install. Rather than a weird artificial deep vibration from my speakers, my exhaust is all natural sounding and only comes from behind me.

        Not worth the money. Airaid came with better quality. Reviews said the Airaid would fit so I purchased this. Reviews were wrong.

        Less mess

        Adding this delete kit makes the engine bay less cluttered. Why do you need a sound tube for the inside when the 5.0 already has an awesome sound? Heads turning as you drive by should tell the story.

        Does what it says

        It caps the opening of sound tube, needed it for coyote swap, would be nice if it could be "cheaper" because I didn't need the firewall grommet

        Blowfish Sound-tube Delete

        Very easy to install. Free up a lot of space with this mod. The stud nut is tough to get to, but you can pull the tube out without loosening it if you apply a little extra elbow grease. Took me about 15 minutes to install with a 10mm socket, pliers, and a flathead screwdriver.

      can the plug that goes on the stock intake be used without the clamp? or will it fall off?

      • We recommend using the clamp that comes with the Blowfish Sound Tube Delete Kit since the plug may work it's way off over time otherwise.

      Am I crazy or is there an extra mounting location secured to a stud on the firewall on a 2017 that isn’t mentioned in the video or directions?

      • When installing the Blowfish Sound Tube Delete Kit, there may be minor variances between years due to Ford making changes and updates. Some 2017 models do have an additional attachment point as you described.

      Does this require any kind of tune?

      • The Blowfish Sound Tube Delete Kit does not require any tune in order to use on the vehicle. The plug simply eliminates the sound hose from the air intake to the cabin which will not require any additional modification to work.
