High Flow Exhaust.  Borla engineers have designed this axle-back to deliver a significant increase in airflow from the factory exhaust system for a dramatic power improvement.

Aggressive Sound. The aggressive sound of the Borla Axle-Back comes from their signature "S-Type" Stinger Mufflers. The Stinger Mufflers are manufactured from aircraft-quality T-304 stainless steel and feature a Straight-through baffled design to produce an aggressive muscle car sound.

Durable Construction.   The S-Type Axle-Back a.k.a Stinger is designed to be a direct bolt onto the factory piping, and features Borla's "S-Type" mufflers. This system is made from 2.5" mandrel-bent stainless steel, and features 4" polished tips for a super-aggressive appearance.

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.

Has anyone put these on a V6? I’m looking at getting them. I’m looking for a deep and loud sound (not stupid loud tho) i have a X pipe to go with it


  • The Borla Stinger S-Type Axle-Back Exhaust will not fit a V6. They will only fit an 05-09 GT or GT500

Would these sound loud and deep like the borla atak with a off road h pipe ?


  • The Borla Stinger S-Type Axle-Back Exhaust would provide a deeper exhaust note but a lower exhaust volume than the Borla ATAK Axle-Back Exhaust.

Is a remapping required after installation?

california legal? Thinking about this with high flow cat mid pipe from bbk and jba short tubes...Is that California legal?


  • The Borla axle-backs are 50 state legal. Unfortunately, the BBK mid pipes and the JBA headers are not.

    What an improvement

    Keep in mind this install was on a Shelby GT500. First off...I am not a mechanic and this install took me about 1:45 minutes by myself. I installed these on my 2009 Ford Shelby GT500. They weigh half of what the stock mufflers weigh. Weight for the Borla set is about 25 lbs. Stocks are about 50 lbs. Removing the stocks was the hardest part because they are so darned big and it was hard to get to all the 13mm bolts. The right muffler was the easiest. The left was a little harder because of the position of the bolts. The right side has 4 bolts and one clamp with a 15mm bolt. The left side has the same clamp and 5 13mm bolts. I believe the instructions are for a GT so that is why there are differences. I uninstalled and installed one side at a time. The stock hangers lined up just fine with the muffler hangers. I thought I had a problem when I performed the last step which was to tighten the clamp. Once I tightened it, I noticed the stock pipes going into the Borlas were still loose. I loosened the clamp and pushed it out to the end where the two pipes overlapped and tightened it down again (there is like a little nipple near the end of the stock pipes that needs to butt up against the Borlas...push the clamp up against this nipple and then tighten it down). Once I tightened it down there was not any looseness that I could detect. I cleaned things up, cranked her up and about chit myself. When the car cranked up it roared to life and then settled down again at idle. I took her down the interstate and drove at various speeds and RPMs. Personally I didn't notice the drone that many people mention unless they are talking about the rumble it lets out when you take your foot off the gas. I bought these at another website for $453 and am very happy with them. I do shop here at, but hey, if you can find the same thing for about $100 cheaper, I'm sure AM would understand. I would purchase these sweet orbs of rolling thunder all over again. Great addition to the 2009 Ford Shelby GT500 Cobra. The only tools I needed for the uninstall and install were 13mm and 15mm socket and rachet deep well and a 13mm and 15mm box wrench. It helps when installing these by yourself to position the Borlas in place and start inserting the 13mm bolts by hand. They will hold the Borla in place for you while you tighten the hanger.

    Unique Sound

    I've owned several mustangs in the past and had a variety of exhaust systems. While I love the sound of Flowmasters and Macs, I wanted something unique and a little more refined sounding. These are pricey, but worth every penny. I've matched them with a Magnaflow TruX with cats on my 07 GT and they sound amazing. They have a very refined, yet powerful tone, especially when you nose in the throttle. If you're not sure about this system, check out some of the vids on youtube. Search Mustang Borla exhaust. You won't regret purchasing these. The tone is, without question, incredible.

    Beautiful sound, beautifully made, wonderful product!

    I've been through a few different exhaust systems on my 2008 GT. Flowmaster American Thunders, SLP Loudmouths, Pypes Bombs, and finally, the Borla Stingers. Honestly, this is the sound I have been hunting for the entire time. They have a beautiful shape to the sound, they are loud, but never just noise. They have a beautiful tone through all ranges. I have BBK Longtube headers, Off Road X-pipe, and these axlebacks are so smooth sounding and everything about them is just gorgeous, from the sound to the finish and fit. Every other system I have had sounded good at one range or another, these babies sound amazing throught the entire RPM band, whether I am idling, or cruising, or flooring it. Highly recommend them! They are one of the more expensive options but definitely the best!

    Wow. This product is awsome!

    I purchased this exhaust after reading other reviews. I am very pleased to say I recommend these to anyone with a S197. They have a a great tone and you can feel a slight gain of horse power. I think mainly because they are so much lighter then the stock ones. Great job AM!

    Good product

    I bought the FRPP version of the Borla Stingers at a discounted price and for the money I spent (about $480) I'm happy with the product. The mufflers...if you can call them that (they're tiny) are well made and look great on the car. I installed them in less than an hour with no trouble other than the passenger side was angled too low and the support bar had to be bent to raise it up. The idle sounds nice and deep and the neighbors don't object when I drive down the street at low rpm's . Cruising at about 1600 - 1800 rpm (legal highway speed 60 - 65 mph with my stock '07 GT gearing) is where the drone happens. Not horrible mind you but it's there when under a load. The good news is that it's TOTALLY gone by 2000 rpm, like switching off a light. Cruising at 75 is very quiet and comfortable ... unbelievably quiet considering how small the cans are. Accelerating through the gears however produces the sound that we all love... a very serious race car howl. Heads turn in awe, teen age boys drool in envy, women and children run in fear, and older Mustang gearheads like me feel young again. If not for the slight drone I'd give these cans 5 stars.

    ok let me start by saying i had an off road h pipe and pypes bombs. it was so loud it rattled the change in my cup holder. i finally got to where i had to change the axlebacks, keep the off road pipe and quieten it down and tone it out. These axlebacks are a must for any off road pipe they add a great tone. they have the perfect volume and sound. the fit was a little off but they will be fine after i tweak it a little. The price is well worth it. it has a perfect sound with any mid pipe.

    Perfect fit on 2009 GT500

    Fits perfectly on the GT500 Cobra. Sounds fantastic, especially in the low rpm range. Love the look of the 4 inch outputs, very boss. Much easier to install than to remove stock mufflers since there's a lot more room to work with the smaller Borla's. Reused the mounting hardware from the stock mufflers and Borla sends along two clamps for attaching mufflers to the pipes. Didn't need (or order) the extra mounting hardware kit. Took me about 2-2.5 hours to install. Really glad I had 13 and 15 mm ratchet wrenches as well as the sockets.

    Only Exhaust Worth Getting....

    Ok, I've owned many cars in my day, from turbo charged eclipse to 87 monte ss with flows on it, and i have to say, this exhaust on my 08 GT makes me grin more than any car I've driven. Buying this, I was worried that it was going to be a bit too loud, me being older and growing out of the ''attention-drawing'' phase, but when I started it up, I was euphoric. absolutely no drone that I can hear, and it sounds good and deep. not too loud at all. Only advice I have is have a shop install it and tak (weld) a few supports here n there, cause it's a bit flimsy and may rattle. I LOVE this exhaust!!!

    Nathan's Review

    I have a 2008 Mustang GT with JLT CAI, BAMA tune, and pypes off road H-pipe. Previously i had flowmaster American Thunder and it was loud, it was muscle, and it was bada$$. I wanted to get a new axle back with a straight through design, no muffler, so every day I asked one of AM mustang experts what they recommend and they all referred me to these borla stingers, every single expert it was crazy. So they hype was on for these, i couldn't wait. Once I installed them and fired her up it was a bit disappointing for me.. It was quite. Too quite for me but the sound was absolutely perfect. I wish they were louder and more aggresive but i am Learning to love them. Heads still turn but it takes a little more throttle to do so then with the American Thunder. Oh and also the drone is absolutely terrible. Between 1500-2500 rpm is straight torture especially when on an incline. It forces you to really punch it to get the nice sound and not be lazy with the throttle. Overall these axle back are very good. Only down fall is the drone and how quite they are, especially without cats. If you are looking for a perfect tone for your car by all means get this axle back. If you are looking for attention coming down the street, either u r going to be spending a lot on gas abusing the throttle to get the sound you are looking for or go for another axle back because borla stingers are not the loudest axle backs available. Ps. I love the polished chrome tips on these as well

    Great Sound!

    These were an easy install, and I am incredibly happy with the results. I'm running stock pipes to the cat with the Borla Stinger S axle-back. I was completely impressed with how much better the car looks and sounds. It's very deep, loud, and great sounding exhaust. The installation very simple. The hardest part was getting off the giant stock mufflers. Just make sure you have a few short 13mm sockets to reach in to that area with. I would recommend these to anyone looking to upgrade. They're definitely worth the price.

    This is the one you want.

    I ran Flowmaster's before running these...if you want an aggressive American sound these are for you. Absolutely no drone, cabin is fairly quiet compared to the Flowmaster's. if you have a heavily modded engine, especially if you have upgraded camshafts these show off that engine noise perfectly. I have the FRPP Hot Rods cams in my '07 GT and these axle backs really show off the lope...and the rest of my system is stock. If your like me and you can't decide which axle/cat back to buy...stick with an H pipe and run these out the back. You will not be disappointed. Not to mention the quality of Stainless used by Borla compared to others is also a must have. Don't be fooled by others who advertise stainless and then those same axle backs are rusted out after two years. "Cough cough *Flowmaster* cough cough"

    Sounds More agrresive.

    On my 2009 GT500, has Kooks headers and catted x pipe, and was currently running a borla touring cat back. It sounded pretty loud under acceleration. I switched to S type axel back, since I had the borla cat back. I have to say my shelby sound more aggressive and makes heads turn. Under normal driving it's not too loud, cops do not say nothing, and I live in Los Angeles, CA. Under acceleration or WOT, those things are loud and aggressive, more intimidating, I must say.

    Borla Stinger S-Type Axle-Back - 5 Star For Sure

    For my taste, these were the best choice. Quality built, and sound great on my '07 Shelby GT. I've been into muscle cars for longer than I care to admit and this is the first time I went for the Borla's. The hardest part of the install is getting the stock axle-backs off.The install for me lined right up, and there was so much more room to get to the bolts it was a breeze to put on. I'm very pleased with them.

    2007 Mustang GT Vista Blue: 9,700 miles-BORLA Stingers Axle-Backs

    Decided to replace my stock mufflers with something more aggressive. Listened to SOooo many sound clips...between that and input from other Mustang owners I went with BORLA. The TOURING were too calm, ATAK were too aggressive but the STINGERS did the job. Won't upset the neighbors and sound great. The sound on acceleration is awesome then calms right down; gets loud as it should on the highway but no drone. Took my mechanic about 45 minutes to install. My first Mustang was a 1971 Mach 1 at age 24. This is my second one 44 years later; I'm 68 years old but still have time left in my life to bring back part of those glory days !

    I installed this mufflers in my 2007 Mustang GT 3 weeks ago and I've been more than happy with them. The overall finish/quality is great. I did not have any fitting issue or whatsoever. The loudness is just fine and you can enjoy your engine. There is a bit of drone between 1600 and 2000 RMS but nothing obnoxious. I recommend this product to any one who wants a good exhaust sound without being noisy.
