High Flow Exhaust. Borla engineers have designed this cat-back to deliver a significant increase in airflow over the restrictive stock exhaust system for a dramatic increase in horsepower and a louder sound.

Aggressive Stinger 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 Borla Construction. The S-Type Cat-Back a.k.a "Stinger" system is made from mandrel-bent 2.5" aerospace-grade austenitic stainless steel, and features 4" brightly polished tips for a super-aggressive appearance. This system also features Borla's popular "S-Type" mufflers for an equally aggressive sound.

Application. Designed as a direct bolt on, this Borla Stinger S-Type catback will bolt straight up to the factory Mid-Pipe without any modifications required on the 2005 to 2009 GT and Bullitt Mustangs to give your Pony a rich muscle car 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.

Borla part number 140135? I've been researching different exhaust systems for my 2008 GT and really like the sound of this catback setup. After researching on Borla's website and shopping around, I was wondering if this is the same setup as Borla's part number 140135 that is listed on their website? Thanks!


  • Yes - this Exhaust System is the Borla 140135 setup.

    This kit is amazing. I had Flowmaster mufflers on my car before with stock exhaust manifolds and cats with a cut and clamp FRPP X-pipe. Now with Kooks long tube headers, catted X-pipe and this Borla cat-back kit installed my Mustang sounds like a monster when I floor it and people will snap their heads over to see what is commanding their attention. In the short time I have had this kit installed I have already received a couple of compliments on the way the car sounds, and when I go through tunnels now I love turn down my stereo, roll down my windows, downshift and enjoy. The looks are incredible, the fit and finish is top notch.

    By far the best catback system for the s197! for best results match it up with an x pipe and long tube headers! gave mine a lot more power and a much better sound that way

    Great and Loud

    Overall the Borla S-type Cat Back system is Great, it is loud and the it sounds great. Had a family member install it his garage and it took him just over and hour. Coming out the back the tips look great and look a lot better than the stock exhaust tips. Driving around town the sound is great but not annoying to the driver and passengers. very few complaints about the system over all and would recommend

    My 2nd upgrade

    I have had my mustang for 3 years now a 2008GT. My fist mustang ever. Last year I purchased a Coldair and Bigger Trottle Body for my car with a Tuner. This year I wanted an exhuast to try and have it sound somewhat like a old mustang. This is close enough for me I love it. It sounds so awsome especially when I start moving in the car and when i get up to speed it its a constant lound rumbling it quiets down which i like. I had a mechanic install it and he told me it was a pretty easy install normally in custom exhuast you have a part that i guess is a tight pinch. He said this didnt have it which is good. I feel more push in the car when i accelerate and I love that. I knew I wanted this exhaust when I read in Mustang Monthly a carshop owner herd a mustang fire up and to him he thought it was a vintage car it wasnt. The price bothered me for awhile seeing as I never spent this much in a lumpsum. It was totally worth it now. I love the deep growl sound it has when you first start the car and it idles. I also picked Borla because I was told from other car lovers that this is to them the creme of the crop. I love it now if gas prices will go down just a few dollars it will be even better. Five stars all the way.

    Nice Cat Backs

    I just purchased and installed the Borla Stinger S-Type Catbacks yester day and it took me a total of about 3.5 to 4 hours. I DO NOT RECOMMEND DOING THIS JOB WITHOUT A HYDRAULIC LIFT. I managed to complete the installation with a buddy, two jackstands for the rear axle tubes and a 3.5 ton jack. Jacking the rear differential will NOT hurt the car. Getting the factory over axle pipes out was the biggest pain in my #$# ...I had to remove the Drive shaft in order to remove the right side completely. Place Jacks on back side of the car on the Rails under trunk space in order to provide overall axle clearance of the OEM pipes. Have fun! Sounds MEAN.....Love em' already...making excuses to drive everywhere now. Funny enough a guy asked me today what kind of "monster" i had under the hood!

    It was nice while it lasted

    I purchased this system last year and had my local muffler shop install it because I don't have a garage area in which to do the work. The day I had it installed I took it for my yearly Massachusetts state inspection at my local Ford dealership. It passed with no problems. This year I brought it in for my yearly inspection and they refused saying that the system was too loud. I argued with them that they had no problems with it the year before but they wouldn't budge. I took it to another station with the same result. They claim that any system louder than stock is illegal so I was forced to have the system removed and have the stock system reinstalled. I'm now the proud owner of a Borla Stinger exhaust system and can't use it. At this point I'm pretty miffed and wonder what system I can purchase that will pass inspection.

    Very Pleased

    I purchased this system for my '06 GT (manual trans). The rest of the exhaust is stock. Sound: Plenty of low-end, but not muddy. There's a distinct two-tone harmony as it revs down between shifts that gives me goosebumps. Depressing the clutch while driving results in a raging river of burble. Civilized at idle or on the highway, very powerful when revving up, and roars at WOT. Install: Had it professionally installed. The driver's side tip is off center (using stock hanger mounts). They said it would've taken some work on the hanger to fix it, but I'll do that myself. Performance: The car hasn't been tuned yet, so gains are minimal right now. There's a noticeable decrease in engine braking power (not necessarily bad). Consider this over the axle-backs; the stock over-axle pipes have a crimp that can impede the performance of more serious mods later. Drone: There is drone between 1.5-2K rpm (like most aftermarket exhausts). It's only annoying if you mash the pedal in that range. A light foot will reign it in quickly.

    I have been disappointed with the sound of this system, the idle sound is excellent, and the sound under heavy acceleration is wonderful, but if you have an automatic transmission stay away. There is this very bad drone nose at 2000 RPM's that is terrible. It's like listening to eight year learning to play the tuba (after a while your ready to take a bullet). The auto transmission is always in the 2000 range so the only thing I can do is turn off the overdrive. I have read many reviews for the Borla Stingers and have found only one other review that has brought it up, I think It's probably not a problem for the guys with a 5 speed stick. I have a 06' GT convertible. The install was easy, and the quality excellent, guess I'll but the Stingers on eBay and try the Touring. Robert G.

    Best sound yet!! 2006 GT Convertabile

    I switched from an MAC after cat exhaust to the Borla Stingers and wow am I impressed. From the packaging of the lyles and mufflers to the finish and direct bolt on with no issues. The pipes came labeled right and left, and there are plenty of online videos to help you I talk then right in the driveway. Some drone at lower RPMS but pretty quiet once you find the sweet spot. But once you step on the gas they scream like a classic Stang should. You won't listen to the radio for a while as you'll just want to enjoy the different tones the pypes give off. Wish I spent the money sooner but combined with an x-pipe it's like a new car. You will increase your horse power with the right set up. Get these pypes.

    love the sound! it was exactly what i was looking for. not too loud, not too quiet. i'm getting compliments everywhere i go. easy install, i did it in my garage backed up on ramps. the hardest part was getting the stock pipes off since i didn't use a lift. ended up cutting them. after that, it was a breeze. as always, very pleased with my purchase from AM. thank you!!

    Near Perfect

    This is the third exhaust I have had on my 2007 GT. Magnaflow Street sounded great but was too quiet (after my daughter got older). Switched to Bassani SS but it was way too loud and high-pitched. It also had trumpeting around 2500 rpms. I did a lot of research and this is the best sounding system I could find. Little to no raspiness and the tone is as deep and rumbly as I could find for the 4.6. The only reason I did not give this exhaust 5 stars is that I don't like how long the exhaust tips are. Some of the other exhausts hide better under the bumper so that only the ends of the tips show - this is just personal preference.

    Great exhaust if you want classy yet loud when stepping on the gas!

    The title basically sums it all up. I had it professionally installed in my 2008 Shelby GT500. The exhaust is pretty quite in low rpm so you don't wake your neighbors up in the morning when turning on the car however it has a strong deep sound when you press the gas. You will difinetaly be noticed when accelerating; strong deep sound. If you want to stay classy yet still be noticed when you want to, then this is the exhaust for you. I would rate the loudness at a 7. Hopefully this helps!

    Great sound, Great product

    So I'm 18 years old this is my third mustang and of course I want my stang to be loud like the last one so I bought this catback exhaust and had it installed on my 06 Mustang GT for about $100 about three weeks ago. It was between the stingers and the ATAK, but I chose the stingers because I figured it was the best bang for my buck. When I first turned it on after install I was a little upset because it really wasn't all that loud and left me regretting that I didn't go with the ATAK, but the guy who installed it told me that most exhausts have a "break-in" period. so I contacted AM and they said there was no such thing and what I heard was what I was basically set with. This left me pretty dissatisfied, but now that its been a couple of weeks I have noticed a HUGE difference in the loudness and sound of the exhaust. Overall I love this catback and am still currently looking for a bit louder sound but sure I'll get it after I get my CAI and off-road X-pipe. Highly recommend this product, it is loud and aggressive and certainly turns heads when I drive by, actually makes the girls here go crazy. I also noticed an increase in response with Borla's great job of unrestricting the airflow and there is definitely some HP and Torque gains with this set up.

    Borla Catback not easy fit.

    While the end result seems good, this catback needed to have the hangers relocated to fit in the stock hanger brackets. The sound once installed is good, with a nice deep rumble.

    Exactly what I expected when buying this exhaust system. Great sounding and was very pleased when it was done. Had a shop install it because I didn't want to wait two weeks for a day off and it was only $80 and it took them about an hour and couldn't have been happier. I would recomend this exhaust system to anyone even though its a higher price tag you definitely get what you pay for in this. Awsome!!
