    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.

    Improves Exhaust Flow. Add even more horsepower and torque to the rear wheels of your Turbocharged S550 EcoBoost Mustang by replacing your restrictive factory Resonator Mid-pipe with a free flowing Flowmaster Scavenger Series Resonator Delete Y-Pipe. A Flowmaster Y-pipe will greatly improve your pony's exhaust flow for an increase in overall performance.

    Muscle Car Rumble. Flowmaster's free flowing Y-Pipe for the 2015-2018 EcoBoost Mustangs not only eliminates the factory resonator to help increase power, but it also adds a deep muscle car rumble to the sound of your exhaust with its classic "Y" crossover pipe design.

    Reuses Stock Cats. This Flowmaster Scavenger Series Y-pipe requires cutting and removing the factory Mid Pipe resonator and clamps in place reusing the stock clamps. Best of all it reuses the factory catalytic converter saving you money and keeping you legal at the same time.

    Stainless Steel Construction. Manufactured in the USA from durable 2.25" diameter free-flowing mandrel bent 16 gauge 409 stainless steel tubing for it's corrosion resistant properties, this Flowmaster Scavenger Series Y-Pipe will improve exhaust flow and last a lifetime.

    Application. The Flowmaster Scavenger Series Cut and Clamp Resonator Delete Y-Pipe is specifically designed for use on the 2015-2018 EcoBoost Mustangs equipped with the 2.3L Turbocharged engine.

    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?

    AustinN

    • 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.

    Will the y-pipe work with the Roush Quad Tip Passive Axle-back Exhaust for the Ecoboost Mustang

    Shotgun42

    • 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,

    Pete

    • 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 have a muffler delete on my Ecoboost Mustang would i still be able to pair it up with this particular Y pipe? And would it make louder?

    BrandonG

    • Yes if you have the existing catback exhaust with a muffler delete you could still use the Flowmaster Scavenger Series Cut and Clamp Resonator Delete Y-Pipe. It would make the ecoboost louder as well as improve exhaust flow for some power gains.

    what the difference between this and just going to a shop and paying 100 dollars for a resonator delete?

    JohanM

    • Hello, JohanMT5U3597630 that would depend on the shop however some differences that you might want to look out for is the quality of the steel is it stainless? The weld points as well as mandrel bending.

      WOW!

      So a while back I installed the flowmaster outlaw axle back and the sound was a huge upgrade at first but I wanted more so pairing the y pipe with the outlaw gave me a deep rumble that doesn’t sound ricey at all. It’s obvious not going to sound like a V8 but for what it is, it sounds absolutely amazing. Videos will never do it justice. Took me about an hour to get it on.

      Great Sound

      Installed both the Flowmaster Outlaw Axleback with the Flowmaster Resonator Delete. Good sound although a tad drone at times. Overall improves the sound of my Ecoboost Mustang. Has a nice tone, loud, however not over the top. Really brings the car to life sounding like a Mustang should. Would highly recommend for those wanting to enhance the sound as well as seeing a little increase in performance. Flowmaster always delivers. Thank you American Muscle.

      Well worth it

      I added this Y-pipe to my 2016 Ecoboost Premium. I'm still running the stock mufflers, so the sound is pretty tame. A little more turbo noise, and very little droning. This modification will not get you into any trouble for being too loud. I can feel that it's a bit more responsive, but nothing "over the top". Highway cruising mileage gains are minimal. Canyon and track conditions may be where it really shines.

      Satisfied

      I was looking to add a little more HP but did not want a loud exhaust sound, I researched for a month and listened to sound bites on a bunch of options,this option is what you want a little more aggressive sound than stock, no drone, and does not sound like a rice burner. I also added the Roush CAI as most suggested on Forums. Just wish there was a option to change exhaust tips w/o changing exhaust

      Flowmaster Y pipe

      Flowmaster makes nice parts that have quality workmanship. The loudness depends on the type of muffler system you attach to it. I'm using the stock mufflers and the car sounds pretty much stock, however their is a small performance gain and it cleans up the undercarriage. Has a weight savings over the stock resonator.

      Pony power

      Freeway performance increased, as in going 65 mph it now accelerates smoother to pass a car. I purchased the resonator delete pipe to get a deeper exhaust tone, and it had done that. I purchased my mustang at a ford used dealership assuming it had a stock exhaust, but while at Ed Hansons to install the pipe it was discovered that I had Flowmaster mufflers, high chamber mufflers because it was not loud and I thought it was stock when I purchased. So now it's louder than I anticipated, but since it's a deep tone my father and friends believe it's how a mustang should sound.

      Flowmaster Y-Pipe

      Wanted something for my ecoboost to supplement my Flowmaster mufflers to bring it to life. Deleting the resonator with this y-pipe is a must-do for all 2.3 owners. The exhaust note sounds deeper and louder, but not obnoxious. I feel a slightly quicker pull on the RPMs as well. Overall excellent product

      OMG

      So when I got my ecoboost mustang the exhaust note was not there. It was quiet, and when you think of a muscle car you want some noise am I not right? So what I did was bought this scavenger pipe with the flowmaster outlaw axle back. It woke the car up, the sounds there, it's quit when you want it to be, and really agressave when you bury the peddle. Does not have the V6 or V8 sound but definitely worth the money.
