Review & Installation Video

Review & Install Video

Hi I’m Justin with, and today I’ll be taking a closer look at the Bassani Axle back exhaust system for all 2005-2009 Mustang GTs. If you’re familiar with Bassani, then you know they make a quality exhaust system that tends to put them in the same class price wise as Borla and some of the Ford Racing axle-backs as well. We’re looking at a very nice, full stainless steel construction throughout, including these highly polished 4” tips and race muffler. The term race muffler usually refers to a straight through design, as opposed to a more traditional chambered muffler, which is great at keeping the sound down, but won’t flow quite as good as something like this. Getting this system installed on your S197 is a simple bolt on task that should take you no more than an hour using some basic hand tools. Now let’s hear how the Bassani axle-back sounds compared to our factory exhaust.

Aggressive exhaust note. Bassani's Axle-Back with it's street performance race mufflers will give your 2005-2009 GT and 2007-2009 GT500 Mustang a more aggressive exhaust note, than that of the stock GT.

Street performance. This Axle-Back system from Bassani features free flowing street performance race mufflers that end with a 4" rolled edge slash cut polished stainless tip that exits in the stock location for great looks and improved performance.

Lifetime Warranty. The Bassani Axle-Back exhaust is precision-engineered from resilient stainless steel for long lasting durability and is backed by Bassani's Lifetime Warranty.

Fitment. This Axle-Back exhaust system will fit the 2005-2009 GT and the 2007-2009 Shelby GT500 Mustangs for great looks and great sound.

Technical Note: Americanmuscle recommends adding the 2005+ Mustang 304 Stainless Steel Exhaust Hanger Kit from the drop down option above, to provide more strength, stability and a cleaner installed appearance. If you have a 2007 Mustang you may need the kit for correct installation.

Really sounds deep and smooth like a mustang should. Have noticed a little power gain as well. Well worth the money. After hearing this, I'm thinking about getting headers to make my 05 gt even meaner

Best Sound

These axlebacks are great, they are quiet when they need to be and SCREAM when you get on it. Driving long distances are also very bearable. Helped out in power and MPG, but its hard to keep your foot ...

Has anyone put these on a 4.0 v6 with a dual exhaust?


How would these be with Kooks Long Tubes and Off road X pipe in comparison to the SLP loudmouths I have currently? Headers and X pipe go on next weekend. I just don't want my car to be obnoxiously loud.


  • This Bassani Axle-Back Exhaust is a much more mild exhaust when compared to the SLP Loudmouth Axle-Back Exhaust, Item 23013. The long tube headers and the x-pipe will ultimately alter the sound of the exhaust, however, we would recommend listening to a few sound clips of stock vehicles with both kits for a general comparison, if you are unable to find sound clips of your exact application.

Since I have an 06 G.T. , do I need to purchash the additional hanger brackets, or will the hangers on the mufflers be sufficient? Thanks, Jeff


  • Hi, Use of the 2005+ Exhaust Hanger Kit is not required to install this Bassani Axle-Back Exhaust, But i do recommend them to provide more strength, stability and a cleaner installed appearance.

Will it be just as loud for my automatic mustang? I currently have glass packs on it but I want something louder more muscle car rumble


  • I can't see any reason why it wouldn't be just as loud. They are definately louder with a nice deep rumble.

    amazing axleback!

    I was looking for something deep and agressive - not necessarily just louder. These have exactly what I was looking for. Louder, deeper, and really highlights what you've got under the hood instead of hiding it! Sounds like a beast even with the stock h-pipe and cats- your neighbors won't hate you when you leave for work early in the AM or come home late. There is definitely a louder cabin noise/little bit of drone but you have to expect that when switching from the soft-spoken stock system. I actually enjoy the extra cabin volume- I don't think I'll be listening to my radio anymore! It was love at first rev. Thanks for the quick free shipping AmericanMuscle!

    Awesome Exhaust

    Bassani has one of the most exotic and clean sounding exhausts out there. This will not make your mustang insanely loud, but neither any other axle-back without taking your cars off or getting longtubes. I received so many compliments with this exhaust... everyone loves the sound. I am getting the whole bassani setup next, longtubes and o/r x-pipe, should sound nasty

    I got a pair for my 06 GT and they were loud, didnt really hear any other new style GT as loud as mine, but I did want something even louder, so I got the X-pipes without the CATs. No Mustang is as loud as mine, AMAZING I haven\'t been pulled over for how loud they is always turning heads. Everyone asks about the exhaust and everyone compliments them. I love them and the LIFE TIME WARRANTY!!!! Bassani has GREAT customer service and will answer any question you have. They will even walk you through the install if you need them to. I will not buy anything other than Bassani just because how happy I am with this exhaust system. Completely bolt on, every easy to install, just basic tools and a jack and stands. Adds a few HP, but I don\'t think it added any MPGs, but I never checked for a difference. And to be clear for those who are wondering about there warranty with the Ford Dealership, this WILL NOT VOID your warranty.

    Absolutely Awesome

    Wow I just installed these a week ago and I loved them from day one. People keep asking me what I have under the hood or what exhaust I have. The tone sounds so freaking good. It has a deep growl in low rpms but screams like a racecar in high rpms. The tips look really good too especially compared to stock. As far as people saying they wish it was can only go so loud with the stock midpipe cause of the cats. Lets just say I'm worried now about cops harrassing me for the volume!

    Great exhaust!

    Just installed these on my 2007 mustang gt, didnt take long and well worth the money! I personally think this is the best all around exhaust for anyone who daily's their car. Not too loud at idle, no annoying drone, and one of the best notes when your getting on it! The only minor problem i had was not reading into the hanger situation for the 2007 year so it took a little more work to have mine centered up, other than that this is a 110% recommendation!!!!

    Looks Good - Sounds Good - Not Perfect

    The Bassani mufflers look to be very good quality and sounded great, except for the loud drone between 1500-1900 rpm. Just have to watch your gear selection to avoid drone. With my 3.55 gears the drone went away at 70 mph on the highway so highway cruising is OK. There is a welded stud at the end of the factory Mustang mid-pipes that was not notched into the Bassasi muffler flange so a 1/2 inch notch had to be cut into the flange so the muffler pipe would fit properly onto the stock mid-pipe. Not a big problem but this should have been addressed by the Bassani factory.

    Old School Rumble!

    I must admit I was a bit apprehensive about fiddling around with my 2008 Bullitt's exhaust. But after installing the Bassani Axle-Backs I must say I have no regrets. Sure it's a lot louder but with the windows up it's still a civilized daily driving. But the real fun is with the windows down at full throttle. compliments my other mods well. Aggressive old school exhaust node.

    Classiest Axle-Back possible

    Being as indecisive as most when it came to ordering exhaust; I was not sure at all what I wanted my Mustang to sound like. After tons of debate I decided on these Bassani Axle-back's. I do not think I have spent another 500 dollars as well as I did this. I was skeptical about the sound and tone of them but if you want the presence and tone that a real muscle car should and not the fake, over-bearing, loud noise that comes from a lesser quality exhaust. Then these are for you. PS: Purchased on Saturday, on my front porch on Tuesday afternoon. 5/5 American Muscle. I will be spending all my paychecks with you.

    Can't wait to fire it up each day!

    After MUCH research, reading reviews and listening to different sound samples, I decided to go with this exhaust for my 2006 GT. My brother and I installed it in about an hour (the hardest/longest part was getting the stock ones off). The sound is exactly what I was looking for and is absolutely perfect for the Mustang. A very nice, deep, throaty sound. Couldn't be more happy. They look and sound great, very, very happy with purchase! And, as always, American Muscle shipped immediately and they were there within days!

    Nice sound

    I never had stock mufflers. I went from muffler delete to the Bassani. The sound is refined, a nice low tone/rumble - not raspy like my muffler delete. Still plenty loud and aggresive, but much better than no muffler. The install should have been easy, but we had problems getting one of the tailpipes off. Once we got past that everything else was easy. Make sure you push the new pipes all the way forward to prevent an exhaust leak - check for any leak, you will see what I mean.

    Hidden Gem

    I had a shop install it, it was a little pricey but I wanted it done right. When I picked it up from the shop, the difference in the sound was incredible. I nearly crapped myself when I first turned it on. When I drove it home, I definitely noticed some increase \'umph\' (even going up hills!). There is a felt increase of power in the mid range but it did feel like the upper range (5K and up) lost a lil umph. Not enough to keep me for discouraging this product though! Bassani is a hidden gem, when people ask what exhaust I have...they assume its Borla or Flowmaster but are suprised when I say it is a Bassani...and most people have not heard of it. If a lesser known brand like Bassani is being mistaken for Borla\'s...they are doing something right! If you are looking for a straight through axleback, this is the best economical choice. My dad never really approved of me adding things to my car (which I do anyway) but when I showed him this and he heard it....his words were \"I think you got your money\'s worth\" which coming from him was a HUGE compliment.

    Easy and fast installation. Not as loud as I had hoped for, but lots better than stock. Gave my 09 GT a little more power and some better MPG. Nice deep sound and doesnt have too much of a roar at high RPMs, so good if driving for long time.

    The Bassani sound

    I've had these on another S197 GT Mustang I've had before in the past matched up with a Bassani o/r x-pipe and JBA shorty headers, it sounded absolutely wicked and sweet! I love the sound these Bassani axle-backs make, Bassani produces a very clean, smooth, crisp, almost exotic type of exhaust note that's a bit different from other's on the market. I bought these again to replace the Flowmaster Outlaw axle-backs I have on the new 06 GT I bought a year ago, I plan on going LT headers and o/r midpipe again, can't wait to hear how it all turns out! Bassani's quality is also top of the line for what you pay, I just had to have these again, I love Bassani!

    Drone is HORRIBLE!

    Just had a professional install these on my 2008 GT, along with Pypes long tube headers, hi flo cats, and X-pipe. The drone on these are ungodly awful. Not sure why or how others haven't mentioned this in their reviews but I'm here to tell you the drone is extremely annoying. Like a buzz sound being drilled into my brain. Can't talk to other people inside the car and forget about enjoying the radio. Having these uninstalled and will try something else, otherwise I will hate driving the car I use to love.
