2018 Ford Mustang GT H-Pipe with Active Exhaust Sound Comparison 

H-pipe or X-pipe? What do you like more?

I'm a "American Muscle" guy, so the H pipe sound of course.

Far better sound IMO than x-pipe. It's a deeper tone with the H where as the X is a higher tone

Thanks to american muscle for putting out all that awesome content over the years. I absolutely love this channel. Keep up the good work.

owning a mustang is so much fun with you guys mr justin .i love american muscle man shopping mods for your car can't be easier than this ,awesome website ,each product have its own demo videos ,thousands of customer photos ,what more can you ask just installed this h pipe to my 2020 gt with active exhaust, it sounds so much better and louder to the point i fall in love with my 2020 gt all over again i can't stop driving the damn thing with a huge smile on my face i love my car i love american muscle making it so easy to modify it

Yeah H-pipe sounds much better. I had the raspy crackly V8 sound. Every V8 needs a deeper sound.

Love the deeper tone of the H pipe! It will be my first mod!!

I’m with you Justin....H pipe all day long, gotta have that deep sound, reminds me more of the original Muscle Car ❤️

I remember when X-pipes used to sound good, but that was on the 4.6L V8... now they’re so raspy they’re just noise without any tone. H-pipe is the winner hands down.

I really like that you show the decibels👍

Justin looks like Captain America with beard in new Avengers movie.

Sounds really good!

Yep, now THAT'S the one that did the trick! Not raspy, smoother, deeper tone, and no backpressure "popping". I have a '91 C4 ZR1 and did this almost identical setup. Resonator, muffler delete with H-pipe and the LT-5 sounds like a beast, especially above 5,000 rpm. Now I'm considering doing this setup on my 2014 F-150 with the 5.0 Coyote.

I’ve heard an H pipe on a v6 and it sounds great. Can’t wait to hear it on this

Love the active exhaust feature!

Subscribed! Great videos 😬

H pipe sounds so good . I had x pipe on my last 2020 and it screamed 😂🔥

I bought the H pipe from y'all recently. This thing is loud on my Roush RS3. And I love it. "If it's to loud , You're to Old". Hahaha

I need an H-pipe for my 03 Stang Love the deep sound Love the vid!

I personally love the deepness of the H-Pipe. Couple this set up with some cat deletes and I'm sure it'll sound way better.

Excellent video Justin as always. Had the H pipe on my other S550. So I’m sticking with the H on my 2018. Great work guys.

Wow. The H-pipe sounds really good. Especially for $150 bucks. I actually ordered a Corsa-double helix X-pipe for my 2017-GT350 from you guys a few days ago. Unfortunately I need to wait 2-3weeks till it comes back in stock but that's ok. I love Corsa products & really liked your video on it. It convinced me to do the resonator delete. Thank you.

That was a very informative video👍 I’m having a H Pipe installed next week on my 2018 mustang you’ve reassured me that I’ve made the right decision Thanks again for posting👍👍👍

I have a new GT with the 10 speed. Will the h pipe cause the car to run richer or will the ecm adjust the a/f??

H pipe all the way. Sounds great. Thanks for doing his video. I was curious about this setup on the new 18's.

Sounds good ! I like he H pipe sound over the X pipe.

I have the Steeda H Pipe and I notice a rasp under WOT.Does anyone else hear that when accelerating?Could it be a loss clamp making the noise?

Do you guys have a double h pipe? Also what’s the best brand to go with?

I got a 2020 mustang 2.3 high performance it comes without resonator :) it was a nice surprise I didn’t have to expend money for take it out

Is this hpipe compatible with convertible (2020 gt premium )too??

Good comparison. It's helped me decide something. The difference between the Stock Normal, Sport and Track modes only ranged about 3-4 decibels. I was expecting more of a difference. The normal sounds good to me. I guess I can save $900 on my Mustang GT build.

I only see Roush and Pypes on your website. Is the one in the video not for sale anymore?

Dang that sounds good 👌 really can’t go wrong with x or h... but I think h is more classic muscle sounding and x is a bit more race car 🏎 and louder too

Just wanna say I had an H pipe installed on mine today with AE and this video does the sound no justice. As a matter of fact no video does the difference justice. You get that deeper throaty sound and get rid of that flat sounding rumble the stock resonator has. And the pops…. The pops are audible now 😩

I just ordered an h-pipe for my 2019 Bullitt! Can't wait!

Impressive that quiet mode with the H pipe is still quieter than stock Normal mode... alright I'm sold

Im sold. Now, which do I get? Heartthrob or Mishimoto? What’s the difference? $100 more for the Mishimoto. Do they both sound the same? I don’t get it need help!!!

Great job Justin , I'm leaning towards the Xpipe , but that's just personal preference , good to see you again , and be careful out there today , we are getting our asses handed to us here in Jersey right now , so needless to say both the mustangs are hiding in the garage!

The sound of these coyote/voodoo engines are enough to make me cry of happiness...they almost bring me to tears...lmao I own an Ecoboost 😢

loving the H pipe over the X pipe. wish more full cat backs would give us the option of a H pipe.

Wow that's ridiculous. I love the 2018 mustangs exhaust. And h pipes are my favorite. Wish I had the 50k for one of these bad boys

5:42 stock redline 5:56 h pipe redline

5:45

Thanks for sharing. I prefer the sound of the factory 2008 Bullitt.

I prefer H pipe; it sounds lower, deeper & more old school. I don't like raspy exhaust at all.

AWESOME

Does this void factory warranty 2020 gt?

The stock resonator is an H pipe so that's why the results... Love H over X

could the active exhaust be deleted ? all the 18 peformance packs i'm looking at come with them , and i would like to mbrp cat back and on your web site it said wont fit the 2018?

Definitely H pipe. Mine arrived yesterday ( I went with the Roush). Thanks AM.

Just curious: H vs. X used to be about horsepower. The volume of sound was something you risked with local law enforcement as a by-product. What are the horsepower ratings for the various systems you've demoed the sound for?

Add some Kooks longtubes to this setup. You don't even need to change the exhaust!

Does the h pipe cause a drone, I live how there is no drone in the active valve exhaust from stock

Digging the H pipe

Which mode sounds the most like a GT without the active exhaust (with or without an H or X)?

H pipes rule. No question about it. D-O-N-E.

They can keep there active exaust , my 2017 we cut out the resonater and welded in 2 pipes cost 75.00 next is axle back but keep in mind the new cars with the mufflers in rear never sound as good as a fox or sn95 flowmaster old School sound 10 4 .

what is the major difference of putting an x pipe vs an h pipe into my 2018 stang? REPLY

I wish I could find a vid of an H -pipe on a gt350r

What is the best way to deceive the sound? I have straight pipe from cats back and sounds awesome but I wanna clean it up a little. I wanna describe to the exhaust guys but how! I want this sound!

Hey AM its time to get back to the Fox body convertible “cobra” y’all said y’all were gonna get back too, love the new mustang but love the fox 100 times more

Waiting on my roush h pipe should arrive end of this week so pumped 😈

Wondering what's the difference between this H pipe vs the roush H pipe thanks

Are the active mufflers louder than the non-active ones from the factory?

AHHHHH!!! I CAN'T DECIDE!!!! Love the "Rice Krispie" of the X... but I've been an old school muscle car guy forever...ugh...when the time comes I'll prolly go w the H...I think....maybe...???😳

The stock exhaust was done so perfect imo by ford, I wouldn't even touch the exhaust. only thing I'd do is put a set of headers on it.

I think a H pipe with short inline resonators installed behind the H to cancel any high pitch freqs.

Curious on how much this affects cabin noise. Especially for those of us without active exhaust.

Does anyone know if the check engine light will come on after installing the h-pipe or do I need a tuner ?

I like them both 🤷‍♂️

I think I’m so early only 150 views😂😂

Stock exhaust is good enough.

Quick question what will piss my neighbors off more x or h pipe?

I like the OE active stuff better. I’m usually an H pipe fan too.

I just want to say that this video does not do the H Pipe justice when it comes to volume. I just had mine installed this morning and the difference in volume is crazy!!

Of course I prefer the H pipe man !

Can we get a straight pipe comparison ? 🤔

Honestly I think stock sounds best but if I had to pick I think the H pipe is smoother and less raspy. A very mellow rumble. What's the weight savings compared to the x pipe?

Does this H-pipe add any power?

H pipe sound all day! what, if any drone at highway speeds is there with this exhaust? The stock Ford tune is quiet at highway speeds. I go AZ to CA frequently and don't want drone. Obviously.

I will go with the H pipe.

Got a Steeda H pipe on my Mustang, best decision I've ever made. Put the exhaust in track mode and listen to the absolute savagery that follows when you put your foot down.

Adding a h pipe or x pipe doesn't throw codes, correct?

Please review "Borla SwitchFire x pipe"

No drag mode? My drag stock sounds louder and deeper

Mustang fans in Australia are still waiting for the 2017 cars. The 2018 is still just a dream for us. Prices have gone up for the car and it's options and now attract the 33% Luxury car tax. So a v8 fastback auto is A$66,000 plus options and on road taxes. Thanks Ford.

Oh damn! 😍 So much better than that nasty x-pipe 🤢

The Mustang looks so much sexier without a spoiler

To be clear x or h all Mustangs sound sweet. Yet, I personally think the old school 5.0 and 4.6 cars sound better as in more like Muscle cars than Coyote cars. There are multiple reasons but we are dealing in exhaust here so it’s my belief that the ricer style muffler location after the axel has something to do with it. On older Mustangs the muffler was in the middle of the car and a long pipe afterward. There is science behind this and I believe that what the long section of pipe does is what engineers call attenuation. Which absolutely affects sound waves and how our ears percieve them. On the older cars I think the x always sounded better but that the difference was not that great. Yet, here I have to admit the h sounds nicer and the difference between them is substantial. Could it be that the x pipe used is a bargian model and not a well desingned x pipe? I know from many tests and things that I have read that all x pipes are not created equal. The cheeper ones tend to not have the true x design that fosters scavenging and smoothes out the ways the engine runs and sounds.

H pipe I like the deeper sound. Vs the X

Do H pipes create a drone? Just picked up a 2019 GT with active exhaust

It sounds like a GT 350 Isn’t it supposed to be a cross-plane crank

I am concerned that you did not have the mic in the same place for both tests.... stock looked like 10' back on the left side and H-pipe was 5' back on the right side... it would have been nice to show consistency.

My girlfriends female schnauzer barks at 120db. I cant have her barking louder than my car. What do straight pipes sound like?

I prefer the sound of a Honda with the 4 inch fart can muffler system

Is it going to void ford warranty?

I prefer the H pipe over the X. The X just shrieks too much, the H puts more bass into it. The drone inside that car is going to make highway trips uncomfortable.

This H-Pipe sounds better in Sport and Track Mode. Also, I’ve noticed the exhaust note between the Gen 1 and Gen 2 Coyote Engine is very different when an aftermarket H-Pipe is installed. I’ve got a Gen 1 Coyote with an MBRP H Pipe and it sounds deeper and “throatier.” I think the S550s are always going to have raspiness even if they have an aftermarket H-Pipe installed.

X pipe for the win. In my opinion
