    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!

        Would the Borla stinger exhaust be too loud for a convertible GT?

        • That will all depend on your preference. It will certainly be loud, but that may be what you are looking for.

        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.

            Perfect Sound

            After reading all the great reviews and watching the sound clip I imported this cat back exhaust into New Zealand. Easy install and exact replacement. Super happy with the exhaust note and rumble. I have now paired this with a magnaflow tru-x x pipe for that extra rumble. Thanks AM.

            Great Sound, CA Beware

            First and foremost this exhaust sounds amazing. I have this paired with a Bassani o/r X pipe and man is it loud. Love the deep tone of this exhaust and it gets a little raspy at higher RPMs because of the X but still a deep tone overall. Get compliments everywhere and it angers non car enthusiasts :) however, I’ve been pulled over three times in the last three months! I’m in CA so with the new law that took place it’s been a headache. Luckily every cop has let me go with a warning but I fear the day I get the $1,000 fine and gotta slap the ol 4 cat h pipe. (sigh)

            Perfect tone and pops

            install took 2 hours start to finish. I got the borla singers because i daily my Mach 1 and feared the Ataks would be to loud when paired with my catless x-pipe. the stingers stay true to the classic v8 tone and turn heads everywhere i go. overall perfect cat back system to pair with longtubes or an aftermarket midpipe

            The sound is amazing

            I spent over a month trying to figure out what type of cat back I would want. After much debate I went with the borla s-type. It was cost effective, sounded great on video, best looking tips on the market, and already had a lot of great reviews. I tried to install these on my own by using jack stands. My stock exhaust bolts stripped and did not want to cut the old one off. I took it into a shop nearby and they put the new exhaust on for $140 in about an hour. Sounded like a whole new car when they started it up. I am overly pleased with this decision.

            Installation was a breeze but also had access to a lift. Love the sound and definitely turns heads. The tips are perfect any bigger and I think they would be overkill. The rounded tips are a really nice finished look

            Borla best exhust

            Really great quality built and sound. Installed with x pipe and catted downpipe and still sounds amazing. Install for just the cat back is simple and fast. Built for best sound and less flow restrictions. Had these on my v6 and sounded like a v8 now I have them on my V8 and sound even better. It's pricey but worth it.

            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
