2018+ Mustang Stage-2 NA Package Adds 90hp+!

If your Mustang is stock, but you want to optimize your performance without adding a supercharger or turbocharger, then our Stage-2 Naturally Aspirated package is the way to go! Serious performance increase at every RPM, more of the good sounds you want, and all around more fun behind the wheel. And all of this is achieved while retaining your daily drivability and stock-like reliability, without negatively affecting your fuel economy… you know, assuming you can keep your foot out of it.
And in this video, we install each component and show the results back-to-back on the dyno. Hopefully you find this information useful! Let us know if you have any questions at all!

Can we see how cams would look on this car. Amazing results so far!🔥

[@travisball566]

I installed cams also jlt is known in the community for not being very good why the dyno had to be done with the hood open

[@shadowdemon5730]

It’s amazing how these relatively simple mods can boost power output by so much. I’m surprised a cat-back exhaust system wasn’t included in Stage 2. Maybe in Stage 3.

[@rileyneufeld7001]

Rarely is the cat back going to be the greatest point of restriction. Maybe a 5hp gain if that.

[@mikaeldalgas-hansen691]

Favorite car, favorite band. Only wish you guys were in Australia!

Nice video, especially the NIN in the background!

Mustang GT plus Nine Inch Nails Music is a bonus.

[@jakenielsen88]

Wow, I really wish this company was also in Northern California

[@cajunqueen1971]

I did all of this except the thermostat on my 2022 GT and I am 10 HP below, so I am guessing around 477 WHP on mine, we had it on the Dyno, but it was 94% humidity that day and the Dyno is outside. It ran right at 476 WHP on the Dyno. Hubby drives the GT500, so I am getting my car to where I can keep up with him! 🤣Great video!

How much did the intake , headers and tune cost for parts and labor?

[@cajunqueen1971]

@@djk856 Right at $9K, the headers are the most expensive, and labor. Now the poor car just sits in the garage.

@@djk856 That is not bad at all! We had a lot of suspension work done, also. We did adjustable camber and caster plates; kelltrac posi locks; and one more thing but I forgot! I bought a Bronco, so the car has just been sitting in the garage since June, we sold the GT500. We are switching to off road, but I just cant sell the GT yet, that 9k we would lose, so it will stay for another year.

[@Shiftnlift]

9k is crazy I didn't even spend half that lol same mods

[@steveandamyalso]

Please understand I am speaking out of ignorance. I happened to notice the long tube headers were installed as they were without any heat protection. Would it not help to contain the exhaust heat before it escapes out the back?

[@everbeeren]

Will adding the headers cause any codes (P0420/P0430) or lights (wrench light) to show up?

[@joshuarichard4493]

I would love to have seen what it would have picked up with an X-pipe I know those stock resonators are a restriction.

[@race-ist5point0]

Did you use 3/8" or 7/8" tube headers?

[@franciscoolivera2194]

Hi would it make a difference if you add a throttlebody 85mm BTB ?

[@jayfernadez443]

Hello question will this Formula work on a 2012 Boss 302

[@packhousetv]

Very happy dyno. Super plucky correction factor. Lol

[@chadjones7722]

I'd like to know what this looks like without the long tubes, maybe just a resonator delete for a more daily driver situation. Don't get me wrong I love the long tubes, but probably not going to do it. Interested in burning some e85 though.

[@MustangJunky]

Long tubes are definitely worth it if u want to squeeze out an extra 35-40 horsepower, my favorite part is about them is how they change the cars driving feeling, u get a lot more low end torque, the only issue is for the price you could also get other stuff that would arguably be better whether it’s cosmetic, interior, but as far as performance after a CAI and e85 and muffler delete it’s all you can really do while staying N/A excluding cams and fuel injectors

[@Whitenoise5.0]

So How much horsepower are you pushing after stage 2?

[@websterzx10r1]

Great video. New subscriber to your channel. Wondering if you guy's ever mess around on the 2015 Mustang Gt platform with a 2018 ported Intake manifold and JLT cold air and free flowing MBRP cat back exhaust and a custom tune?

[@NationalSpeedInc]

Thanks for the sub! We do! There are gains to be had with the gen 3 intake for sure.

[@10mm_brosTV]

No stage 3 video?

[@leviefrauim1425]

Solid gains and rational packages but curious why you folks don't remove the resonator and add different mufflers. Got to imagine there's easily another 10-15 RWHP lost there, plus a better tone.

[@TheGevShow]

i think theyre showing what theyre package will do. any other mods you do are a bonus. i dont think this is a "lets see how much power we can make" video. its more of a "heres a really good ad for our package and here are the numbers to back it up" video

[@gerrym75]

I'd be happy with this package on my 21. Solid gains and not crazy loud. Most videos I hear with muffler deletes sound way too raspy and would give you the shits after a few months

[@dariusholt678]

Now wait just a minute. This is 100000% ripped footage from the last video I just watch lmao.

[@iamkingrichard2032]

How much is the stage 2 cost?

[@TheTriviumhead]

If you plan on doing headers, even if they're catted, expect a "wrench light" and P0420/P0430 codes. The higher flow will cause these codes, and no, your tuner will NOT turn it off. Its illegal to do so. Putting spark plug non foulers on the rear O2 sensors may help. In theory, they move the O2 sensors out of the stream enough to fool them into thinking theres a normal amount of flow.

[@nipbakka]

Hey bro shut up with all the rubbish no one wants to here your bloody negative comments these guys are doing a great job of letting us people know what up grades do if you can’t show proof then shut up

[@nozopoke1782]

That’s only in the USA. Tuners can turn them off anywhere else in the world

[@jeyfs7355]

I dynoed at 483 with just catless headers, full exhaust (fully straight pipe), flex tune, and just a drop in K&N filter (stock air intake). I might have to give an aftermarket intake a go to see if I can break that 500 whp.

[@miles__9369]

Did you change the intake and see a difference?

[@jeyfs7355]

@@miles__9369 No don’t think it’s worth it, my tuner told me not to do it as open intakes suck in more hot air. I’m boosted already though with hellhorse twin turbos.

[@robvas]

NIN...+20hp

[@TheTriviumhead]

Cold Air intakes don't do much for you. 5HP tops. The HP boost you get from "tune required" intakes is mostly from the tune. A simple 93 octane tune can get you as much as 20HP. Its all marketing fluff, that I fell for too many times. Open air element CAIs just get heat soak unless you're on a track, at the strip, massive heat soak. Save your money for a better intake manifold, OPG's, cams, etc, or boost. Dynos can vary as much as 5+ HP per run, and if the car isn't at operating temp for ALL runs, the numbers are bogus. Cold oil causes parasitic loss.

[@xlaostha704x]

Yea, this is the reason why I went with just an aftermarket intake filter. I went with a Green filter.

[@Shiftnlift]

You say that yet gt350 and 500 comes with open element intakes.
