2021 Mustang: Stock Exhaust vs. Steeda X-Pipe & H-Pipe on the Dyno!

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.

Just installed my h pipe yesterday and I was not prepared for how loud it was in person 🤣

2:00 Stock
3:06 X pipe
4:14 H pipe

Thank me later

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!

[ReallyStrongGuy]

Great video! I chose the H Pipe for the sound on my blown Mustang. The few HP is nothing compared to the rumble.

[StevoRado]

Love this exhaust comparison. It was perfect and what all other exhaust comparison videos should follow.

[skipgumphrey]

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...

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.

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 losers.

Running the H-pipe setup on my 2020...thing of beauty.

[larryboydjr]

I have the H pipe and love the sound and just added the steeda axle back

[chrism.]

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.

[TheLoneWolf_andCoyote]

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.

[AndrewBaker]

I will gladly given up a couple horsepower for the deeper sound of a H pipe

[TonyDMan]

Definitely the X-pipe! That's the true Mustang sound we're looking for. Job well done.

[oldrover]

Decisions, Decisions, I have to pipe the Video through my entertainment center and listen again . Thanks for posting .

[DanielPerez-vtez]

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!

[StevoRado]

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.

[granthenneke]

The X pipe sounds insane at 7500 rpm. Straight up nascar!

[AStanton]

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.

Awesome Video Guys! Perfect comparisons
