Or it can be installed with Borlas XR-1 Long Tube Headers deleting the stock factory cats for even more power making it perfect for off-road use.

High Quality Construction. Constructed from ultra smooth mandrel bent 2.75" stainless steel tubing to improve exhaust flow the Borla catback exhaust system includes a X-pipe and features two straight-through "Stinger" mufflers with 4.5 inch polished stainless steel slant tips for aggressive sound and impressive looks.

This Borla Stinger S-Type Catback Exhaust System with included X-pipe has a versatile design that allows it to fit 2011-2012 GT Mustangs equipped with either the stock factory manifolds or aftermarket shorty headers installed. Or it can be installed on 2011-2012 GT Mustangs with a set of Borlas XR-1 Long Tube Headers by deleting the catalytic converters. Installation Note. When installing this X-pipe/Catback kit on a BOSS 302 Mustang, you'll loose the functionality of the factory Side Exhaust pipes.

Will the Borla Catback Exhaust and X pipe bolt up to the BBK long tube headers?

Deranged2013 Year: 2013 Model: GT

  • Unfortunately, these would need to be paired with the Borla XR-1 Long Tubes for a proper fitment. If not going the LTH route, you could use this combo with shorty headers or your stock manifolds. Hope this helps!

Question Resolved

Will I see a big difference in the low end torque with this system? I don't want to lose that low end pull the car has. If I stay stock headers and cats, and change to this system from the x-pipe out, I been told it will just take all that pull away.

scottncrn Year: 2011 Model: GT

  • The short answer is not so much. In my experience, the low end pull is still there for the most part. My butt Dyno really can't tell the difference. Other than the stinger cat-back, my only other go-mod is a CAI (stock tune). Perhaps with a more heavily modded machine it would make more of a difference. By the way, I just saw a video on youtube of a dyno run on a basically stock 2011 GT with the Stinger cat-back installed (before and after). The max HP gain was +9, and it was near the top of the curve From what I could tell, in the lower RPM's, the runs looked basically identical. It's obvious that the car is breathing better, but for 1200 + bucks, there's a lot more bang for our buck out there if you're just worried about increased power. That said, I don't regret a penny of it. That Borla signature sound is just so sweet.

Already have the axelback I bought the s-type axelbaack for my 2011 gt and now I want the full cat back can I purchase from American muscle?will I have any complication with installation?

Timidigi Year: 2011 Model: GT

  • I purchased the s type axel back and the decided to go cat back. I didn't want to pay to return axelback, so I found over axle pipes and x pipe on competitor site, I was disappointed these part aren't avaiable here. When you purchase separately clamps were not included. Also very disappointing. $1300 and you can't include clamps? Any way... I had this installed 4/6/15. They welded it in do to no clamps. Pipes aren't centered, it's been a mess. Going back today 4/8/15 for adjustment. It's been a headache for me. Do your reaserch, and make sure you have what you need the first time! Sigh.....

    This system is awesome. I have been a Flowmaster guy all my driving life (almost twenty years with two other v8 mustangs and two trucks), NOT ANY MORE. The tone of this exhaust is nasty. You need to hear it in person, as any video or sound clip just does not give you the true sound it possesses. I had gt500 axlebacks on before, and they just were not loud enough. This package is alot louder, and has alot more of an aggresive tone. Absolutely no drone with this system. You can accually feel the exhaust somewhat now as you romp on it. The volume IS controlled with the gas pedal. It is almost as quite as stock at idle (but alot deeper), and screams nasty beast at WOT. I gave it 4 stars on volume because it is not as loud as the ATAK system, and is no where near as loud as a cat delete system (of course). The price is a little steep for the majority of us, but you do get what you pay for. The materials are of top quality, and this new system went in easier than the stock one came out. Overall, this kit is kick@$$. American Muscle is super easy to deal with, and gets your packages out the door quickly. Thank you gentlemen for the great customer service.

    SICK

    I've been a flowmaster guy for over 20 years...always 40 and 50 series type stuff. I still love the sound, and consider it the benchmark musclecar tone for comparison. That said, I recently picked up an '11 GT, and like most of us with hotrod running through our veins, looked to upgrade the sound along with improving airflow as a platform for future mods. I had nearly made up my mind to get a set of hushpowers (based on sound clips and reviews), but then I just happened to run into a dude with a '12 GT at a local convenience store. I heard him fire that thing up and I nearly dropped a load in my pants...so good I needed a private moment, if you know what I mean. I ran over and asked...he had the Borla ATAK cat-back installed. When this guy pulled out, every head in the parking lot turned to see the low flying jet; it was that loud and angry. It wasn't the volume that really got my attention, but the tone. Fierce and deep and just plain mean. I thought that if I could get that tone and drop the sound output by a few bazillion decibels, that would be perfect...at least for me...we all have our preferences. I did some research on Borla's offerings and decided on the stinger s-type. I've had them installed for about 2 weeks and have honestly not bothered turning on the stereo. I can't get enough of listening to them. The tone is rich and low; not as mean and loud as the ATAK, but still aggressive and throaty when you get in it. My gas mileage has dropped about 1 mpg simply because I want to put my foot in it all the time. It's a beautiful thing. The bottom line: Yes, it's a bit expensive compared with many others, but the first time you fire it up, you'll cease to care about that ever again. Ever. The tone is great without being ridiculously loud, and can be quite tame if you can control your right foot. Fit and finish is pristine. Cruising through residential neighborhoods isn't a problem...again...if you can control yourself. There is NO DRONE at highway cruising RPM, which for me is worth the extra cash (I've got a manual with 3:73's and cruise at around 70 if you'd like a frame of reference...probably about 2100 rpm or so). So, if you're like me and love a rich, aggressive sound that (mostly) won't put you in bad with your neighbors, you'll be thrilled with this exhaust. Have fun out there.

    Awaken Your Inner (Mustang) Beast

    I spent all winter listening to countless Youtube exhaust videos and eventually settled for the S-Type Catback, and I couldn't be happier. This system is well worth the price of admission. It gives the car a deep, throaty, and aggressive tone and will turn some heads for sure. Your gas pedal is the volume control - it's tame when you want it to be, and is nearly silent (zero drone) under highway cruising speeds. But when you put your foot down, this thing absolutely howls. The exhaust tips stick out a tiny bit further than stock, which some people may not like. That being said however, my shop that did the install cut the pipes a tiny bit so the tips do not stick out. Shipping from American Muscle was also VERY quick so thumbs up to them!

    I was contemplating Borla ATAK, Magnaflow, and some other options and am completely satisfied with my purchase of the S-Type. I'm a spirited driver and this exhaust allows you to cruise at low volume without drone and open her up and let it scream at WOT. The quality is awesome as the 304 stainless construction is superior in every way to 409 (which the stock and many other aftermarket systems are comprised of). The after-cat X-Pipe has also given the 5.0 more efficient outflow and increased the power of the stang.

    Great Product

    Having looked at quite a few cat/back systems and listening to countless videos on U/ Tube I narrowed it down to ford motorsports and Borla. The Borla was a little more than I wanted to spend, but when checking pricing on American Muscle, I found the Borla S Type system on sale, I purchased it and could not be happier. The sound is fantastic and no Drone at highway speeds. My hats off to American Muscle for having a great product at a great price.

    Best sounding exhaust, Great quality

    Had this exhaust installed last summer and haven't gotten tired of it since. Best sounding exhaust out there for the GT mustang in my opinion with nothing but great comments from others. Has that perfect throaty, powerful noise volume without being obnoxious. Highly recommend this exhaust!!

    smooth and powerful sound

    I have had the exhaust for 2 + years. did a lot of research and bought it before i had even picked up the car from the dealership. i installed it withing the first 48 hours and it was not too hard. every thing came apart easily and went back together smoothly. did it in a garage with it blocked up about 2 feet off of the ground. pretty easy overall. the tone was beautiful from the start with everything stock. it is throaty and very very smooth, but not too raspy. tough to explain honestly, but it truly does get tons of attention. always get compliments from the older and the younger crowd. the starter at the drag strip told me i had the best sounding car there. all muscle cars from all eras, and all i had was a catback and a Bama tune. the tune really brings out the additional power and the exhaust note comes full circle with the tune. it is a thing of beauty. i recently added a JLT intake the the exhaust note is now even deeper. next on the list are kooks LTs and an h pipe. this exhaust is expensive, but if you plan on doing future mods you want more than just an axle back. quality is truly top notch. zero drone through any gear. the sound is never overbearing. no complaints at all. i would rather people not buy this just so i can have the best sounding car out there, but i have to recommend that you buy it. it turns heads and gets girls in your bed! made that last part up, hope this helps!

    Not as good as I thought it would be

    Shipping and packaging was great. The system sounded descent outside my 11 gt. Welds and steel top notch. The volume is loud. After 2200 rpm it gets really loud. The sound doesn't quit either. For the price I expected more. Hanger fit tight. I had a slight drone at 2000-2100 rpm. Perhaps it didn't like my 373 gear. The system definitely is one that you can feel. It tickled my inner ear at 4500 rpm which got irritating. That's a lot of vibration of you ask me. I also had a rattle after I did the install, which I couldn't find. The rattle came and went even after a few heat cycles, This system will end up on Craig's list.

    • Response from AmericanMuscle

      Even with the 3.73 gears, we haven't heard of this system having drone at all. Borla has a million mile warranty. I would highly suggest giving them a call directly at your earliest convenience to talk over the problems you are facing and to see what would be the best remedy. If you need any additional assistance after speaking to them, do give us a call and we'll be happy to help.
