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.

Application. The Borla Stinger S-Type Axle-Back is designed to fit the 2005-2009 GTs, 2007-2009 Shelby GT500s and 2008-2009 Bullitt Mustangs.

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.

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

MustangMikey

  • 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 AmericanMuscle.com, 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.

    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!!!

    Stingers

    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.

    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.

    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

    sounds like the roar of a lion some drone

    the exhaust is amazing has a great deep tone and they are pleasantly loud although they do drone in the 1800 too 2000 range it is not too bad I miss the more throaty sound of the gt500s and they had less drone but at the same time they quited down and that I don't miss overall I would say the borla is definitely better especially the startups, they are priceless get a lot of compliments way more than when I had other exhausts

    Excellent exhaust note. I've heard lots of different axle-backs and I aways like the Stingers the best. I'm dinging 1 star off the fit because the slip-over end of pipe was slightly bent in (not round). My installer had to form it back into shape. Wasn't a big deal, but should have been caught at the factory. My 08 didn't need the optional hanger mounts AM sells.

    Great for O/R setup

    I originally had the Flowmaster American Thunder on my 06 GT and they sounded good until I put an O/R X-pipe on. The sound was horrible to me, which was really loud trumpeting sound accompanied by horrible backpressure sounds. I had a shop put these Stingers on for me and wow what a difference it made. There is no trumpeting at all, sounds great. The Stingers came from AM very neatly wrapped and in great shape. I constantly get comments on how good my setup sounds. They sound great throughout the RPM ranges. One thing to mention is that I have a 4.10 gear and the stingers have absolutely no drone when I am going 70 on the interstate. Great product. I used to think Flows sounded best but these have change my mind.

    What a pair!!

    These are really nice! What a sound they produce. I can't say enough. Just listen to my before and after video from stock GT mufflers to the Borla at http://www.youtube.com/watch?v=jHT2us8LMHQ&feature=share&list=UUVexYbj2OoA9r864GgJULJw. Nice.... Our convertible has the stock exhaust (manifolds, cats, H pipe) and we added the Borla Stingers for some extra GROWLL. My only problem is they drone in our convertible at 55-65 mph crusing speed (apparently a common problem around 1700-2800 rpm on some mustangs) and it will drive you out of the car OR make you deaf. We like to tour our corner of the US in the spring and fall, and that drone will not work for us. They are great and I would recommend them for those looking for a louder throaty muffler on their mustang. AND they look GREAT!!! I will update later on how or if we were able to correct the car cabin drone problem. I hope this has been helpful.

    Nice addition to the car...

    Car now sounds like the muscle car it is... A bit pricey but they're Borla and you are getting one of the best known products available. I do have a drone at low rpm and at times through shifting but expexted it. It does not last long once you get to desired speed. I also added sound proofing to the trunk and it helped a bit. I would buy again on my next mustang.
