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 power and sound.

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 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 to be a direct bolt on, this Borla Stinger S-Type catback will bolt straight up to the factory Mid-Pipe without any extra modifications required on the 1999-2004 GT, 2001 Bullitt, and 2003-2004 Mach 1 Mustang to give your Pony a rich muscle car sound.

will this fit my 00' mustang v6? i have a 2000 mustang v6 i was wondering would this fit it

sniperpenguin

  • As a direct bolt on, no this will not fit your 2000 V6. However, if you couple the GT catback with the V6 dual exhaust adapter kit, attached below, you will be able to install both without any problems!

Can this somehow fit my 97 gt? With some time of alterations, can this fit my 1997 Mustang gt? I love the sound and want nothing other than borla.

Kicker

  • Yes. Take this awesome system to a shop who has experience with exhaust fab work and welding. A Mustang shop or a speed shop in your area will have no problems finding appropriate hanger locations to mount the system.

Loudness? How do these compare with the slp loudmouth catback, because I want to get the loudest and the sound clips are all pretty close.

Sage

  • I wouldn't invest much in the sound clips. When i got my SLP Loudmouth and installed it on my 04 GT it sounded nothing like it, the clips likely have modified midpipes,headers, or both. In my opinion, the SLP might be a little louder but also not as smooth. I believe that the Borla provides the best sound. If you want good sound and truly want to do it right, do the headers and midpipe as well, not just the catback, this will give you best sound and performance.

what is the best mid pipe to use with this? an H pipe or an X pipe. which is louder? which is deeper? and off road or catted?

33wings

  • Highflow Cats produce a deeper, though a bit quieter tone with an H pipe. Offroad X pipe will be loud and raspy. ProChamber midpipe is excellent for sound and most importantly, performance.

I have an 03 GT Convertible do you think that these would be to loud for a convertible? I want something that sounds very good without it being to loud or annoying, this is my everyday driver for about 8 months of the year. This would be my first mod to my car after getting it 3 years ago. Also, will this give me a decent amount of HP?

tanman

  • Ohh My, These would be perfect as long as you absolutely remove stock cats and install hi-flow metal substrate cats. It will sound incredible. Awesome set-up. Congrats

    Insane Exhaust!

    I paired this with the Pacesetter H-pipe for the V6 and let me just say...WOW. This exhaust sounds beautiful, no drone at any speed. Doesn't even remotely sound like a V6 anymore. From a cold start, it roars and idles with a nice growl. In the 1000-1500 RPM range, it quiets down a bit, then from 2000-2500 it growls and from 2500 up at WOT it screams! The car sounds like a beast, and I'm no longer embarrassed of the rusty stock pipe and pathetic sound. I just feel bad for my neighbors when I start it up in the morning haha. I had my mechanic install it, and it took about an hour/hour and a half and cost me $125. Totally worth every cent, and I will buy Borla for all my future Mustangs

    It's Alive.....

    This exhaust really brought my Mustang to life. Better horsepower and sound. I don't really care about the power, I just wanted it to sound like a Mustang should. This catback was the right choice. I was very nervous about it being too loud and raspy, but paired this with MAC pro-chamber midpipe and all you hear is Thunder! Seriously. I have zero rasp and nice drone. Loud is subjective and to me a deep growl and a nice bark when you hit the pedal is exactly what you want. It is music to me ears!! Local shop installed it and had no problems!! 4inch tips give it a smooth and very nice finish. You can't beat this exhaust in my opinion.

    Sounds Awesome

    This exhaust sounds awesome! Turns heads and makes your car sound like a new mustang. The installation is pretty simple. Here is what I recommend. Uses jack stands to put up the back of the car. This will give you more clearance to get the new pipes over the axle. I used my ramps. It was difficult to get the new exhaust pipes over the axle, especially on the passenger side. Also, to remove the stock mufflers from the exhaust hangers, use wd-40 and a strong pair of channel locks. Dont pay 20 bucks for some specialty tool. I would totally recommend this product. It sounds great. Low, and bubbly at idle, and when you floor it, it sounds amazing. Borla is top quality. Very happy with my purchase!

    Best Money I've Spent So Far

    I did a whole lot of research before I finally pulling the trigger, going through video after video on YouTube trying to find the perfect one and I found it. Is it loud? yes, but mainly when you want it to be. If I am just cruising around you can barely hear it (no drone at all). But if I drop a gear and get on it my grin goes from ear to ear. I use my car as a daily driver and have no problems with noise besides if you are trying to be very quiet leaving for work in the morning. Took about an hour and a half to put on, very simple and straight forward especially with a lift. In summary, it was hands down the best money I've ever spent on a car modification.

    Alright got these borla stingers about a week ago had the installed the next day and holy cow it's such an amazing tone always turns heads even cops heads thankfully they smile ha. But always get compliments from both young and older crowds. Next I'm going to get the bassani mid pipe from there website because am doesn't have the automatic set which makes me sad :/ but I would definitely suggests everyone to buy these. And I did have these installed at a professional mustang shop in auburn cost me $235 for instal.

    Love this system!!!! Total change to the car.

    Did a ton of research before buying this system. I used to have the same car with flowmaster. Even though flowmaster is a great system, I must say I am much happier with the Borla. The exhaust note is fantastic and it seems like a real quality system. Very happy!

    Best Catback

    Got this catback on my 04 GT and its just plain awesome. I didnt know what catback to get it was so hard to get one i looked at every other brand but in the end Borla is the way to go..this catback is stainless steel and it comes with borla's million mile warranty so you know its going to outlast every other cat back. The sound is how a V8 muscle car should sound..not obnoxiously loud or raspy like a fart can muffler and not too low its got the perfect roar to it..of course will sound better if you add an aftermarket midipe as well..If you dont know which way to go id definetly take the borla route. you wont be disappointed!

    Borla Stinger S-Type Catback

    I have been looking for an exhaust catback for over 3 years. over this period of time I looked at every single exhaust and studied and listened to them all. It was one of the hardest decision I have been faced with. But in the end, Borla topped them all. I listened to all the sound clips of it and i just want to say that Borla sounds sooo much better in person then through speakers. sound will get distorted through speakers. If you are struggling to pick an exhaust, go for Borla. You wont be disappointed. They look sick too!! I could honestly say I was more happy to get my Borla exhaust then the mustang GT itself. There is only one drawback thow, your neighbors will hate you, But who cares about that, there just jealous. I highly recommend the Borla Stingers S-Type Catback!!!

    Borla Stinger S-Type Cat-Back Exhaust

    I just purchased and installed the Borla Stinger S-Type Cat-Back Exhaust system on my 2001 Bullitt # 3807. I could not be happier with the outcome. Installation was simple and not cutting or welding required. The Stingers are all bolt on and are a simple installation. However I did have access to a hydraulic lift at the Fort Sam Houston Auto Craft Shop. Although, I did had to cut the stock exhaust to maneuver it out though. The sound is incredible! It provides a deep bass sound with a tough growl. There is no highway drone either. At high speeds it quiets down, but in 1st, 2nd , and 3rd gears it sounds it sounds very tough and intimidating. I highly recommend the Borla Stinger S-Type Cat-Back Exhaust system!!!

    Great Product

    Borla hit the nail on the head when they made this catback. Very nice system, that not only sounds incredable...but also looks good too. The rolled tips make a huge difference in appearence. I still remember the day we had it installed on our 03 GT and the guy fired up the car...My wife and I were in the waiting room and we both looked at eachother and she asked me if that was our car. In other words...you want something that'll turn heads, then buy this system...Thanks Borla and American Muscle!

    Borla cat-back

    Instructions said install time is 3 hours-my wife and I got it done in just about that time. Had a few minor glitches interpreting the directions, but overall, it was fairly simple. Have had the Borlas on for a week and immediately noticed more torque/horsepower. A little loud on the low-end or at rapid acceleration, but we've gotten used to it and it does turn heads. No excess noise at cruising speeds. Nice, deep rumble when you want it.
