      Video Review & Installation

      The Borla Stinger S-Type cat-back exhaust is available for all '05 to '09 Mustang GT owners who are looking to pick up some serious volume with a deeper, throatier, and more aggressive muscle car grown and a top-quality construction. The installation here is going to be pretty simple. It will be a direct bolt-on, no cutting or drilling required. Expect one out of three wrenches on our difficulty meter, which we'll talk more about later on. As you just heard from our sound clip, this thing is pretty much no joke. It definitely amps up the volume of your 4.6, but doesn't go too overbearing. It is the middle child of the three Borla ATAK options, the beginner one being Touring as a more mellow option, this being in the middle, and then the all-out screamer is the Borla ATAK. Now, this one I'm giving three out of five on our loudness meter, because it does give you a pretty nice rumble at idle. Once you start opening up the throttle, it gets pretty rowdy. But it doesn't have any drone inside the car. Now, if you're really looking to wake the neighbors, you'll probably want to pick up the ATAK that I definitely give five out of five. But this one is more for the guys looking to pick up the sound, get a little bit more aggressive, but not go too over the top. This one does offer some of the top-quality materials that you can possibly pick up for your exhaust, with a mandrel-bent, two and a half-inch, aerospace-grade T304 stainless steel, with a straight-through baffle design. That pretty much just helps you get the sound clips you just heard and the sound I just described to you. Now, with that said, it does offer at the end four-inch, huge, polished stainless steel tips, which are extremely attractive coming out the rear end. This thing not only sounds great, but it looks good while doing so on your Mustang. In my personal experience, I have had the Borla Stinger S-Type on my own '95 Cobra, it sounded absolutely incredible. I had it paired up with an off-road X-pipe, as well as some long tubes from BBK, and the thing just paired together great. I've had nothing but good things to say about it. I would definitely recommend it. You'd probably expect this to have a pretty high price tag, but honestly that's not the case. You can pick up the Borla Stinger for just about $650, which in my opinion is pretty affordable compared to some of the other options out there. Now, to kind of give you an idea of the different sounds Borla offers, the Touring edition, which does have a more involved muffler system, as opposed to the bullet style here, will run you about $1,000 for the more mellow sound. This one is in the middle, so if you're going for the raspiest of the rasp to wake those neighbors, the Borla ATAK runs about $800. The installation is extremely straightforward. It will be a direct bolt-on swap. I'd say have a ratchet and socket set on deck, as well as a jack and jack stands, or a lift if you have access to one. Give yourself an hour or so in the driveway or garage at home, and I would definitely give this one out of three wrenches on our difficulty meter. The first thing you want to do is get your Mustang in the air and support it on jack stands, or on a lift if you have access to one. Use a ratchet and socket set to unclamp your mufflers or your axle-back from the over-axle pipes, and pull them out of the hangers and set them aside. Use the ratchet and socket set to also unbolt the flanges from the over-axle pipe to the mid-pipe, pull those over the axles, and set those aside as well. Just a little tip here to help you along your way. If you find that the bolts are pretty rusted on after a couple of years of being on the road, you might want to have a can of PB Blaster on deck to kind of loosen things up and help you get those out a little bit easier. The Borla over-axle pipes will go right onto your factory mid-pipes and tighten down using the hardware provided, and the new Borla mufflers and tips will go right into the factory hangers and isolators, and clamp right over to the over-axle pipes. So if you're the owner of an '05 to '09 Mustang GT, you might want to check out the Borla Stinger S-Type cat-back exhaust, available right here at

      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.
