    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.

    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.

    • 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.

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

    • 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.

    • 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.

    Is it possible to get this exhaust installed with jack stands ?

    • Although it is not the most ideal and safe method of installation, this exhaust system can be installed with the vehicle of jack stands. However, American Muscle highly recommends installing the system on a full car lift system for safety and ease of installation.

      Sounds great, quieter than expected but that’s where the off road x comes in. Pulls a little harder maybe but the sound is really what you’re paying for, install was a breeze, fits perfect, took no time at all, all high quality stuff

      Super mean and aggressive

      Makes my GT sound like a cobra with an offroad x pipe. Had to install on a lift, very hard to get the tailpipes over the axle when using jack stands. Overall very impressed.

      Borla S Type

      Probably the best sounding exhaust on the market. I had flowmasters on it before I switched to these and will never buy anything but borla again. These are loud when you want and decently quiet if you're not on it. Very good looking too.

      Not as expected...

      After finally watching several sound clips, I finally went with this exhaust. Paired JBA Long Tubes, O/R JBA Hpipe, and the stingers, I wasn't too impressed. Sounded good but was no where near as loud as expected. In fact my flowmaster 40s with cats were still louder. For some reason I was shipped cats but the guys who installed them did not know I ordered them without them and charged me $100 to cut them off. Once that was taken care of it was a little louder accelerating especially around 2500 rpms and WOT but that's it. I And I didn't receive my MIL eliminatators in the mail, very disappointed in you AM. Won't be purchasing any more performance mods anymore from y'all.

      Sounds Good, Looks Good

      Bolted right up as any exhaust made for this car should. Paired with BBK's o/r H gives it a nice sound for sure. Exhaust tips look good and its nice to have some shiny stuff under the car again.

      Love this catback

      To start off - I have BBK ceramic coated headers, BBK O/R H pipe and this catback. My review is based on uninstalling my old catback. I went from a MAC Flowpath catback to this. I wanted something more exotic sounding and this catback delivered. Paired with a BBK H pipe it gives you the deep aggressive tone without the sound "that everyone else has". The install was simple, but keep in mind I am removing an old aftermarket catback. Getting the muffler pieces over the axle was easy - put the jack stands on the frame. This allow the axle to drop and you can fish the muffler tubes over the axle. In all it took me maybe an hour to install once I get the car in the air. Word of caution - these are loud. The idle is tame but once you get on it, it wakes up. I had this paired with a VRS X pipe with my longtubes and hated it. Too raspy and tinny. The BBK H pipe gave me the sound I was looking for. It pops and crackles on decel and even pops like a firecracker if I get it just right. I frequent a local mustang shop and when the car is started outside it shook the walls inside. It's loud compared to the MAC Flowpaths I had. Only downside? It makes BLATTT noise at certain rpms with an H pipe. People killed this (while keeping the deep tone) by going with a prochamber. Good luck!

      Dang Loud

      I'd say these are a bit louder than I planned. Paired it with a catless X-pipe. Every guy I know says it is awesome. No lie, kids from the neighborhood come running out of their homes to see whenever I leave the house and give it a little "extra" gas.
