Great sound
These sound great it’s the sound you’re wanting out of your S5 50. The only complaint I could give is that The quad tips are a little small and they don’t offer them in black.

Exact Sound I Was Wanting
I've had this axle back exhaust now for about two weeks...and it's been all smile. I have it paired up with a Ford Performance X-Pipe and the setup freaking growls! As many others have noted, no drone when driving, but when you lay the hammer down you definitely notice how it opens up! The fitment was perfect and the chrome tips are perfect. Had it installed at a local performance shop. I had been wanting this exhaust for over a year and finally pulled the trigger on Black Friday. This is definitely the best sounding axle back exhaust I've heard. If you've been going back and forth, do it...you won't be disappointed.

Aggressive, mean, sounds like a muscle car!! 2020 GT stock resonator
As a dad, this sounds SOOO MUCH BETTER then stock. It has a deep rumble. And surprisingly quiet at low rpm. But once you get on it the exhaust comes alive! Sound so good throughout the rpm band. I can’t imagine a resonator delete, this setup is perfect for me now. I have the stock resonator. Sounds like a muscle car should sound! Videos don’t do it justice!! Best money spent!!!

Bring out the beast in you Pony
I paired this Steeda axle back with a previously purchased Steeda Xpipe, and wow! This is not for the faint of heart. Early morning cold start ups will wake the neighbors. After it warms it quiets down, but when you step on the go pedal, heads turn. Installation was pretty simple. I did have to adjust the hangers because the hung too low.

Steeda Axle back
Cold starts are loud and mean when paired with a hpipe. From what I can tell, there is a tiny increase in cabin noise with this setup versus the stock setup but NO drone at all. There's a nice rumble at idle and a lot less rasp compared to the stock mufflers. It's loud when you want it and quiet when cruising. Overall I'm pleased with this setup. Hopefully, they will have more options for color and tip sizes in the future.

Steeda Axlebacks
2019 GT 10 speed, bought Steeda Axlebacks together with a 1 7/8 Pri. Texas Speed Headers, Borla Switchfire midpipe, hi flo cats, so when i start (cold), it wakes the dead, added 2 resonators (generic) and it tamed it down just a bit. still wakes the dead. lol! Idle is mellow tone, accelerating to 40 mph, alittle coarse but acceptable, but W.O.T. is loud and Authoritive ! sounds so killer! Cruising no drone at 75 mph. i am 59 so i need something quieter. maybe a turbo muff! good product though, nice welds, 304 SS, tips too! had to cut and bend hangars to make tips look rad.

Best on the market
I absolutely love the Steeda axle back exhaust. Mine is paired with a Ford Racing Performance x-pipe. I am a little surprised how much deeper it made my 2020 gt sound. I've always ran Flowmaster mufflers on my mustangs and trucks. But when I did my research and came across the Steeda brand, I didn't waste any time getting them. The axleback looks very high quality and is a lot cheaper than most others on the market. Nice, deep tone down low in the rpms, and really comes alive in the higher rpms. Received mine within 3 days from ordering.

Should have bought this sooner!
Amazing sound!!! Videos do NOT do Justice.... especially paired with an H-pipe. Keep in mind that it’s slightly raspy up top even though it is not an x-pipe but you still retain the low growl down low. I already got compliments the day I got on when I drove it around town to break it in a little lol. Don’t be like me and debate buying it for 6 months but it now and never regret it! Also, I spray painted them black and it hold well if you use a black primer spray paint!

Sits too low, also the tips should be wider. Sounds pretty good. Very loud when paired with H pipe.

2019 GT Convertible
I purchased the Steeda axle back exhaust and h pipe during Steeda's Black Friday sale. Both items were received 4 days later and in perfect condition. The car sounds amazing and exactly how a Mustang should. You will not regret making this purchase.

Love
Stopped by and picked the Steeda axle back backs up and have them paired with the Steeda H-pipe. I love the new tone that has been added to my car.

mr
Last week I pulled the trigger on the axle back with a h pipe.. When you drive normal it can be quiet in fact I took my 90 year old mother to the doctor in the car about a half hour ride. she didn't mind it at all. I did show her at one point how loud it can get. The point of this review is if your afraid to get because it will be too loud don't worry it only gets loud when you hit it...But when it does get loud it's the roar of the coyote Gods it sounds so good. As usual with steeda the parts are all top notch.

Stang
The sound of these Steeda axle backs and H pipe with remaining factory piping in between sounds bad ass. Very loud cold start but mellows out. This is a loud exhaust note. At about 4grand on the tach they turn from raspy to a deep growl good sound. When out of the gas or 6 gear at 80 mph very pleasant no drone and a little more noise than stock. If you want a mean sounding 5.0 this is the way to go. Great price and very hi quality. Again the exhaust note on this setup really changes at about 4grand really deep good sound!!!

Steeda Axel Back for 2018 Mustang GT
Love this exhaust. It sounds so good. No drone at highway speeds Just a little louder than stock at Idle but comes alive with just a little throttle. Nice and loud when I want it to be. Exactly what I wanted. The tips are thicker and nicer than OEM.

great sound
I watched a ton of videos before pulling the trigger on this axle back. I couldn't be happier the car is drone free while cruising, and absolutely roars under full throttle. Cold starts are amazing as well. Simple to install, especially after I did the full length jacking rails. Maybe 30 minutes under the car.

Best Axle-back. Period.
Finally! After all of the trial and error of finding the right exhaust note, I found these! These axle-backs have the perfect growl when you let loose. But are also tame if you are on the highway or in a higher gear. I have these installed with an H-pipe and could not be happier. The quality is also the best that I've seen. Smiles are guaranteed! Just put these in your cart and enjoy your well deserved Mustang note!

Great option
I've used just about every possible muffler on one of my 30 Mustangs I've owned, but this was the first time I tried Steeda's offering. I'm VERY happy to report the quality was great as it is with their suspension parts, and I absolutely LOVE the tone ! It's louder than stock , but not too obnoxious even for this 50+ year olds daily driver, and I've already done the resonator delete. Thanks Steeda !!!

Great value for money
I love the sound of this axle back. It sounds very mean and aggressive with little to no drone at cruising speed, however, fitment is a little off, the exhaust tips sit a little too low and I had to cut the hanger about 3/4 of an inch to make it fit better.
