Stephanie with AmericanMuscle.com, here with the Flowmaster Scavenger Series Cut and Clamp Resonator Delete Y-Pipe, available for 2015 and up EcoBoost Mustangs.This Resonator Delete Y-pipe is going to be for the S550 EcoBoost owners out there that are looking to increase the sound level of their car quickly and without necessarily having to spring for an entire new exhaust system. Replacing the resonator with a Y-pipe can totally change the sound of the car, even with the stock axleback still installed. The resonator delete is firstly going to free up some power and, of course, volume since it will be replacing that restrictive factory resonator with a stainless steel Y-pipe that's more free flowing. And like I just mentioned, one of the cool things about this Y-pipe is that you can pair it with your stock mufflers for a change of exhaust note, or you can run it with an aftermarket axleback. But either way, you'll still maintain the use of your stock cats which will save you money and also keep you legal at the same time. A great side effect of replacing that resonator with the Y-pipe is a good deal more turbo noise, which I always think is a good thing, and you're going to notice a lot more turbo noise no matter what your axleback situation is. So on a scale of one to five, with five being the loudest, and keeping in mind that you're still going to have your stock cats, I'd rate this Y-pipe as a solid two with the factory axleback. It definitely opens up some sound, but it's not overbearing or crackly or too raspy with the factory axleback. But just to test things out a little, we also installed a Flowmaster axleback so you can hear what they sound like paired, and I'd rate that combo as a four on the loudness scale. At that point, everyone's going to hear you coming, and the pair have more of a raspier tone for sure, with a decent amount of crackling and lots of turbo noise and gurgle. As far as price goes with this Y-pipe resonator delete, it costs right in between $200 and $300, and as of right now, it's the only Y-pipe on the site that's currently available. And if you think about it, if you pair this with an aftermarket axleback, you've effectively created a cat-back for your EcoBoost, and you paid a lot less for it. You're welcome for that little side note. As for the install, you will be reusing your stock hardware, and like the name suggests, there will be some cutting involved but nothing too difficult. If you take your time, it's probably going to take about two hours to complete, and I'm going to call this two out of three wrenches on the difficulty meter, but mainly just because of the cutting that's involved. So overall this is a stainless steel resonator delete y pipe that can work with either the factory axleback or an aftermarket one. It also works with the factory cats, and it's going to free up some sound from the EcoBoost. As always, check it out more for yourself, and for all things Mustang, keep it right here at AmericanMuscle.com.

Fits perfect replaced resonator and makes pops paired with axleback amazingly. I have the MRT axle and it pairs up perfectly and is a very good sounding exhaust. Takes off that very restricting stock resonator and sure is worth the buck. Check it out on my insta @ktbaka_stang.Helpful (1)

I was informed prior to ordering this y-pipe that it would pair up with the MBRP Catted downpipe I also ordered with no modification. Come to find out upon receipt of the items that the y-pipe and extension piece of the down pipe are finished in 2.25 diameter, which means I can’t fit the extension piece into the y-pipe without some modifications, which means now I have to go to the muffler shop and spend a couple of hundred dollars to get the system installed an expense and time delay I wasn’t expecting.Helpful (4)

Easy install. Not loud just a little purr. You want loud you will have to install some different mufflers.Helpful (4)
Will this fit a 2019 ecoboost with active exhaust?
This will fit all 15-19 Mustang EcoBoost models.
Will the y-pipe work with the Roush Quad Tip Passive Axle-back Exhaust for the Ecoboost Mustang
The Flowmaster Scavenger Series Cut and Clamp Resonator Delete Y-Pipe should mount in the stock exhaust locations. So since the Roush Quad Tip Passive Axle-Back Exhaust would connect to the stock exhaust, it should work with this Y-pipe.
I purchased the Flow Master Outlaw Axleback #525581 a few months back and like it. Now I want to know if this Flow Master Ypipe #389694 will mate directly to that Axleback system. I don't want to buy the Y pipe and then discover during the install that the Y pipe ends don't mate with the Flow Master outlaw axle back piping and I have to go search for a adaptor for each of the Y pipe ends to mate to the axleback piping. Thanks,
The Flowmaster Scavenger Series Cut and Clamp Resonator Delete Y-Pipe will pair up with your axle-back system with no problems! It will be a great addition and definitely help free up some horsepower.
I want to add this to my Roush Power Pack level 2 I already have on my ecoboost. Would this work with the Roush power pack tune?
The level 2 Roush Power Pac's axleback exhaust will work with the Flowmaster Scavenger Y-Pipe. Since this unit will still utilize the stock catalytic converters, it will be compatible with the tune.
Would this Y-Pipe work with the factory active exhaust on a 2019?
Yes, this would work with an otherwise stock application.
We have not tested that application, however this is designed to fit an otherwise stock Mustang, so as long as the downpipe in question is also designed to fit an otherwise stock Mustang, it will be safe to assume that they will fit together.
Clamps can be used for easier uninstallation/reinstallation in the future.
The Flowmaster Scavenger Series Cut and Clamp Resonator Delete Y-Pipe will not require a tune.
This would be a 2.25" tubing and would not mate with the 2.5" axle back that you have.
Yes, this can be used with the Borla ATAK axle back.
Yes, the NXT Step Performance axle back exhaust is compatible with this Y-pipe.
The Flowmaster American Thunder Axle Back Exhaust will mate with the Flowmaster Y-Pipe with no/minor modification required.
Yes, this mid pipe and the ford performance by Borla touring exhaust will work together.
This Flowmaster Scavenger Series Cut and Clamp Resonator Delete Y-Pipe will not affect any emissions devices on your Mustang and will be smog legal in California. This would also work with any kind of muffler delete axle-back as long as it was compatible with the stock y-pipe.
