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.

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!

Exhaust sounds great and also looks great as well. Nice and Loud when on the throttle, and actually quieter than stock when idle or cruising.

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.

No drone
Sounds great both inside the car and outside the car, my last GT had MBRP race and had a really bad drone, Steeda isn't loud inside the car until you accelerate

AWESOME Sound!
Sounds way better than a Rousch. Has a awesome deep tone with the Steeda H-pipe I installed also. I get tons of compliments on how mean and aggressive it sounds! I'm very pleased with sound. Absolutely no DRONE! You can't go wrong with this axle back. The cold starts make everyone turn their heads in awe.

Steeda axle back
Such a great sound for my 18 GT. In fact, it sounds so good that I haven't even installed the steeda x pipe that I purchased at the same time in fear of changing the exhaust note. No drone what so ever. Only issue I'm having is not being able to keep my foot out of the throttle to hear em. And their so quiet at cruising speeds. Shipping was blazing fast to. Install was a breeze once i picked up a couple rhino ramps at the local. So happy I went with this axle back!
