- One of the most cost-effective ways to bring out the sound in your #Mustang is by removing your factory resonator. While the 2021 Mustang #GT sounds great from the factory, we like our cars a bit louder. In this video, Chris will show you the difference in the sound and performance between an H-Pipe and an X-Pipe on the 2021 Mustang GT on the #Dyno.

3:06 X pipe
4:14 H pipe
Thank me later
THANK YOU!!!!!!!!!! LOL
Thankyou so much
Cheers😊
Just installed my h pipe yesterday and I was not prepared for how loud it was in person 🤣
I will gladly given up a couple horsepower for the deeper sound of a H pipe
Its a moot test anyhow, the sizing of pipe work in either seperate dual, H or X is different for a given baseline Hp. Just swapping an x and h or comparing to a true dual of same diameter is only giving you a sound comparison NOT a comparison of HP potential.
I have a H pipe and love that sound I don’t like the X pipe sound but it sucks we sacrifice a little.
@@1forddan done with correct pipe sizing there is no advantage to either
@@8power857 what do you mean if I have a Steeda H pipe I can make the rest of my exhaust bigger and make up the difference?
@@1forddan no necessarily bigger, that depends on the open header peak Hp. Careful setup and dyno trials have to be used to perfect any system. I can make up a test with full dual, x or h that will make whichever one i want look best! You cant just bang in whatever comes in a nice box and expect its correct for every combo, shelf stuff is typically made with 3 things in mind, profit, looks, to be better hp wise than stock, they are far from perfect.
H pipe placement V collector length MUST be correct. H pipe diameter V its length is kind of important, pipe diameter after the H is very important, muffler type and tailpipe diameter(which is usually best slightly smaller) all need to be correct for your combo.
If made correctly, h pipes make 'slightly' more peak hp and x pipes are more tunable making 'slightly' more average hp/tq in a narrow band around a given/selected a rpm.
For a streeter choose whatever sound you like best. But realise that these youtube 'chuck on a h or x tests' are not showing you the full potential of each setup but are showing you only what a generic bolt on item does 'for the specific combo in the test'.
I've worked on Mustangs for years and though the X Pipe gives more power, I love hearing an H Pipe with that American muscle tone the way a Mustang should be heard. My 2006 Mustang GT did lose horsepower when I switched back to an H Pipe from X Pipe but, I gained some torque and it sure puts a smile on my face!
Awesome! Sounds really good!
H-pipe sounds better and the difference between it and X-pipe is negligible. I would go with the H-pipe. This mod is primary for sound anyway.
100% agree. Just about to do H pipe for mine.
Love this exhaust comparison. It was perfect and what all other exhaust comparison videos should follow.
Awesome Video Guys! Perfect comparisons
I just had my Steeda X pipe installed on my 21 GT PP definitely made the car sound very good my exhaust mods are completed I'm very happy now.
Great video! I chose the H Pipe for the sound on my blown Mustang. The few HP is nothing compared to the rumble.
Nice gains. Great information
Great video! Great comparision!
Had a Corsa dual helix pipe on my Shelby GT 350 with resonator delete and it sounded knarly and raspy - Ferrari like. Very European.
Not at all like an American muscle car should.
Swapped out for a Steeda H pipe and improved the sound tremendously. Deep throaty muscle car sound - and no more raspy cackling. Very pleased.
Always been a H-pipe guy myself 🔥🔥🔥
X pipe worked out great for me on my 2016 5.0 with RTR Magnaflow axlebacks. Good combo since I'm not really into obnoxious loud. Steeda makes some good stuff!
X pipe = exotic sound
H pipe = muscle sound
Power difference = negligible
yep. this is why my cobra has an h pipe, two magnaflows, and a couple dynomax superturbos :D
Great video!
I prefer the tone of the H on my 19 PP1. Seems perfect with a Steeda axle back as well. Could be due to being old school coming from extended Foxbody experience, I like the lower pitched rumble but it is what it is. I don’t think you can go wrong either way...
Yep.
Love the H pipe!
Go with the flow !
I have the H pipe and love the sound and just added the steeda axle back
Great video 💪
This is a great comparison video! I'm sure many people wonder about the power, sevevenn though they usually want the sound.
X Pipe, baby! More exotic sounds and more power! 👍🏼.
Decisions , Decisions , I have to pipe the Video through my entertainment center and listen again . Thanks for posting .
H pipe for me. Good vid guys!!
I'm impressed. So glad I put the X in my car last year. I thought it gained, or feels like it at least. Now I'm not sure I gained the 8 hp you got since I never put it on the dyno, but I'd be thrilled with that gain. And the sound is awesome to boot! If someone tells me they can get me 6 extra hp just by changing 1 part, cost not being the limiting factor, and still sound hot! I'll take it. I want every advantage I can get no matter how small. Sometimes it's the small things that makes the difference between winners and well..... losers.
You gained more than 8hp. Thisbtest was done on 6th gear.
@@ZoubeirsWorld very true.
My 2017 with and X- pipe with GT-500 axel back is sweet music no drone at 2300 rpm with 3.55 gear
Running the H-pipe setup on my 2020...thing of beauty.
I have a 2019 without active exhaust and want the H pipe, but it’s hard to tell how much louder it is on video. What % would you say?
@@RowlandsAdam it's really the pitch that's different. The X is more raspy...has a higher pitch than the H. They'll both be really loud. I posted a few clips on my page if you wanna hear the H at start up.
@@RowlandsAdam I have that setup and also posted a few clips on my channel. The H pipe is much deeper in person, cold starts are throaty af and sound withbactive is orgasmic. Deff try the Steeda H pipe, its a fantastic high quality piece.
Have the x -pipe on my 2017 mustang love it with GT-500 axel back.
The X pipe sounds insane at 7500 rpm. Straight up nascar!
I'm about to have a Steeda X-pipe installed on my Mustang GT with active exhaust. The active exhaust defaults to normal mode every time the car is started. I'm hoping to now leave it in normal and get a little extra sound.
I feel like you touch on it but what type of torque gains are you seeing before peak torque? Looks to me like both H and X are making 30ft lb over stock at least before 4500rpm or so thats huge!
Just traded in my ‘17 GT that had the Steeda X paired with outlaw axle backs. Super gnarly, aggressive, and just plain mean growl at will, but was definitely LOUD inside and out. Gonna go with the Steeda H for my new ‘21, but wondering if you guys are able tune that year model yet? Also have the hardcore closed intake from my ‘17 on standby.
This answers a question I had ab power gains and an xpipe...I had mine done at an exhaust shop and he did awesome work but I have cats xpipe and no mufflers and I noticed the power gain immediately...I busted loose in 3rd leaving the shop and it didn't act that way stock
I chose the H-pipe for the muscle car sound. Not a fan of the raspy sound of the x-pipe. HP gains can be had other ways also. It's a matter of what you want to hear
H Pipe sounds amazing on the V8
I have a double helix x-pipe. Does that make more or less hp than a standard x-pipe?
Definitely the X-pipe! That's the true Mustang sound we're looking for. Job well done.
Not one day that my x pipe doesn't make me crack a smile! Everyday is a good sounding day. 🙂
PLEASE FOR THE LOVE OF GOD, STOP PLAYING MUSIC OVER EXHAUST REVS/DYNO
they both sound great but yea X-pipe is where its at!
I have the Steeda H-pipe and Magnaflow Competition axle backs on 2020 GT PP1. Very deep and not annoyingly loud. It does have some drone but I don't mind it.
Question: Does the Tune make much difference on the Mid pipes? Switching one X to a H pipe , tune is the same or do you need to Re Tune?
@@foristjI don't think you would need to update a Tune when only changing the mid-pipe, however, I have no direct experience in tuning cars after an aftermarket build.
Thanks for the reply Steve, I agree with you that it shouldn't matter.@@StevoRado
Correct! No tune required for the mid-pipes!
What kind of results would I find in the 6spd 22 GT?
I’ll go with Malcolm X 2 in 1 power and great sounds
what kind of dyno are you using that a 3rd gen coyote is getting 371whp on? losing 90 bhp to drivetrain?
So the only thing I really took away from this. Either the dyno I went to wasn't calibrated right, or my car has a tune on it. Cause my 2015 base GT dyno'd at 390 hp. All it has is a catback exhaust, and cold air from what I can tell, which a previous owner had put on.
Is this with a recalibration or just parts?
The stock resonator on the GT is essentially a straight through design so I'm surprised the h-pipe actually adds a bit more power.
Wow really that much difference in hp between the two, obviously it’s not allot but it’s something
Isn't the h-pipe supposed to be 2/3's of the size of the exhaust itself? That h-pipe is the same size as the exhaust.
I like that x pipe
"H-PIPE" ftw!
See, a lot of people are only focusing on the peak numbers. At 2500 RPMS, both the H and X are outdoing the stock by near 30 wheel horsepower...
Hpipe with Steeda aggressive tone axle back.
Love🎗🎗🎗
Cool video with automatic. What about a 6 sp manual 1:1 in 4th gear test? I have a 2020 GT PP1 with active exhaust you can test!
Cool.
Hey Steeda - in person how much of a difference between X & H regarding sound? It's a little difficult to tell on video. I have a 2021 Durango RT, Tow N Go with 5.7 - I removed the large mid-muffler suitcase, installed X-Pipe and 2 Dynomax Race Bullet Resonators. It sounds great with no drone, but if an H-Pipe can give me even a deeper sound I'm going to replace X with an H. And does it matter how long the tube is between the 2 pipes (how big should the H be)? But this will be a $300 job and want to make sure it's worth it. THANKS! 🏁🏁🏁🏁
Tough to say with the different engine, but it definitely helps change the tone on the Coyote Mustangs! -Chris
It seems like a full piping system starting under the cats...not only a resonator delete !
Nope, just a resonator delete! -Chris
I’d take the h-pipe and I don’t even have to remove the seats for the different in ho from the x-pipe. Plus if the x-pipe is more expensive for just a hand full of hp, it’s not worth getting the x-pipe
X pipe all the way!!!
X pipe for me. I'm spending coin on something, I want power. If I want more sound, just go straight through.
Awesome review would be great if you could have added the Borla Switchfire as the 3rd option..
I'm going with the X but next time you do an exhaust review please do it without the music.
What you all came here for...
X @2:43
H @3:49
I have a 2016 GT convertible, how bad is drone with either option? Prefer the deep H tone but would go X if significantly less drone. Hope you all are appreciating that active exhaust! Lucky ducks!
The drone is pretty negligible in both options really. There is a slight bit more in the H-pipe but nothing that would be noticeable to most people.
These do not trigger a check engine light after install correct?
No, they do not! -Chris
Definitely H pipe, I would hate to go X pipe with headers and have my car sound like it’s dragging tin cans behind it every time I accelerate.
This
Its a moot test anyhow, the sizing of pipe work in either seperate dual, H or X is different for a given baseline Hp. Just swapping an x and h or comparing to a true dual of same diameter is only giving you a sound comparison NOT a comparison of HP potential.
What is this "quiet mode?" Never heard of it and honestly, it should be illegal. And H pipe for the win, of course, for nothing other than the sound. But if anyone thinks they're going to feel those few extra HP because of the X pipe over the H pipe, it's all in your mind. H pipe every day, all day.
"Quiet mode" is the first of 4 modes that you can activate with factory active valve exhaust. The others are normal, sport and track. Since I have an H-pipe on my 19 GT, it is great to use this so when I leave for work in the morning, I'm not bugging my neighbours. Why should it be illegal? It was developed by a Ford engineer for this very reason.
@@rod928s4 It was an attempt at humor, sport.
Is running in 6th gear causing it to read lower overall?
Yes, it's also cutting off at 6800 rpm, making me think they are still hitting the limiter.
I'm rather surprised how low that car is reading on a dynojet, even in a Georgia summer. The gains would be separated more if results matched most 18+ autos that put down around 410-415 stock in similar air. For reference, my 18 with a manual, x-pipe, and muffler delete put down 434/399 with a dynojet set to STD correction for 3 back to back pulls in 92F humid Missouri.
That's exactly what I thought too... that car should be over 400hp! Maybe because it's an A10?
I think it’s because they were limited to 6th and not 7th gear for a 1:1
@@KC-eh6by no, that's not it. My GT on a different dyno in 6th gear on 91 octane got 405RWHP SAE. Dyno's are just VASTLY different.
This car didn’t rev as high as some do. Stock they seem to rev o 6500-7100. This one is a little low revving. This car would make huge gains from a normal tune as it would rev out to 7700. Some cars stock for whatever reason already rev out to 7100 and do t gain as much on a tune since it is already in the power and. Either way thisnis a great dyno to show the difference on same car same day same dyno. x pipe increase is insane.. these cars are at 6000+ tpms the whole race or highway roll so x pipe is a way better option if your racing as it gives tons of power up high and consistent
I would prefer to hear stock, h pipe and x pipe back to back all in track mode. I think valves open is what everyone is interested. Doing all the modes puts too much time in between the sounds we are looking to hear

Went with your H pipe on my 17 GT,
Just traded it in for a 2023 Performace Pack and ordered an x pipe too try something different . Both cars are stick shifts
Will the H pipe fit a corsa sport axle back? Or will I have to custom fit it?
Hey Rey - It will work since the Resonator Delete H-Pipe will mate up to what's left of your factory piping since the Corsa Sport Axle-Back connects further torwards the rear. Hope this helps! -Chris
@@steedaautosports thank you for the reply 🤘🏼
Which would give the more exotic/nascar sound? X or H pipe?
An X-pipe should bring out a more exotic and European sound -Sam
I couldn't notice any sound differ between x & h.. Possibly the camera not justifying it?
& excuse the uneducated question but wouldn't 2 straight pipes be the better route for exhaust flow?
X is more high-pitched and raspy, H is deeper with a more old-school muscle car sound. In most cases, it's best to have a mid-pipe where the tubes cross to equalize the exhaust gases/pulses on either side of the engine.
@@steedaautosports great information! Thank you!
Want my v8 to sound like a American v8 what do you think im going with
H-pipe
The x pipe sounds raspy on camera but in person it's great and more horsepower.
There's a video on CZcams called 2018 Mustang GT resonator delete first impressions by Tom the car guy. His video helped me decide which X-pipe to run with. Listen to his Mustang when he starts it for the first time with his Steeda X-pipe.
@@AStanton1966 I went with the mbrp
Does the h-pipe have any drone?
Hi,
There is a very slight amount, but going by the owner they say it is almost non-existent -Sam
X pipe for sure. I went h pipe for sound but now that I know I’m giving up some hp, I’m changed.
The power is so little though and if you mod your car say Supercharger, Procharger, Turbos, tune, etc...... you'll get more torque with H and torque is what wins drag races.
X pipe i would like to know if a 3 inch cat back with an x pipe would have some power loss i have a 2019 gt mustang auto with a Roush supercharger and i been thinking of buying one
All Mustangs love long tube headers, x pipe, and 3 inch exhaust, especially boosted.
It makes them louder and faster.
Why play music over the dyno clips?
Why would you put music over it???
Trying to get the absolute best from your car, go X pipe. Trying to make the car if your dreams and who cares about the numbers, then get whichever one you like the sound of better. 90% aren’t tracking it anyway so the numbers are just for ego
What color is that
That color is called Grabber Yellow. Definitely eye-catching!
*Hpipe*
OEM sounds like a wet fart. H-pipe doesn't sound much better. X-pipe sounds mean Af.
Great video
Is this without a tune?
No tune! -Chris
377 to 385 is actually 8 hp gain .
Stupid question...isn't the GT rated at 460ish HP stock? Why is it almost 100hp down?
I'm sure there's a logical reason nobody's mentioning that and I'm just stupid.
Hi,
The 460hp rating is at the crank while the power we show on the dyno test is to the wheel. You can expect a loss of power from crank to wheel through the transmission and drivetrain.
Should of done the H-pipe first. Engine was already heated up. I've seen other dyno tests showing no difference in either regular X or H pipe.
We waited for cool down in between each test. Hope this helps! -Chris
That because there should be basically no difference....think about every car manufacturer with a "performance exhaust" like the Corvette. They say it adds what? 5hp? 10hp? To the crank.....it's negligible if the headers and cats are untouched AND there is no tune update. I don't believe the hype
377 hp that is the lowest dyno pull I've ever seen for a 2018-2021. Coyote Gen 3's are pulling 410 to 425 depending on the dyno and tranny.
Their dyno is one that won’t let it reach full speed. It is revving out and madding the dyno out so that’s why you can see on the dyno it’s at like 6700ish. Peak power is around 7100-7300. Which is where you would get another 30-35 hp. Autos are around 405-430 stock so this is normal for such low rpm.
@@xGR1MxREAPERx Thanks for the info!
@@xGR1MxREAPERx idk, I just watched another stock gt dyno at 6500 rpm and it hit 408.6 hp.
@@justanotherone685 I can make your car have 350 or 425 stock lol, ju St adjusting parameters on the dyno. Don’t look into that too much. Look at the end result after mods. You can check your power with 1/8 or 1/4 mile times and speeds easily. With a certain weight car and xxx horsepower it should run xx.xx times etc. if you do the research on these cars from 2018-2021 they typically dyno 385-410 stock auto and 395-425 stock manual.
x pipe sounds better imo
X pipe
X pipe more down low grunt and definitely more HP on the dyno
Xpipe
H pipe sounds better and deeper tone
Would have been better without music
x pipe.
