      Review & Installation Video

      If you're the owner of a New Edge Mustang GT or Mach 1, you might be interested in ditching the factory exhaust to beef up the sound a little bit, getting you a more aggressive, throaty muscle car sound, in which case the Borla S-Type Stinger delivers. This one I'm giving three out of five on our loudness meter, it definitely beefs up that sound, gives you that muscle car tone and a really throaty note without too much rasp, without going overwhelming. Now, the price of this kit comes in right over the $600 mark, which in my opinion is a very, very worthwhile price. This in particular is one of my favorite exhaust systems for the SN95 and New Edge generation just because it sounds so good and it's not too overwhelming. So, you already heard the sound clips, so you know what to expect in that department. But what about materials and construction? Now, Borla is one of the main brands on the market known for making some of the highest quality systems available with 304 stainless steel from head to toe. Now, that's something that's a really good choice for the guys out there seeing a little bit of road salt during those wintry weather months. The factory exhaust and lesser qualities like 409 stainless or aluminized steel is definitely going to be more susceptible to rust and corrosion whereas the 304 stainless will hold up a lot better. Now, aside from that you're getting two and half inch mandrel bent tubing throughout here which gives you a really good exhaust flow. So, you will see a little bit of change in throttle response, definitely a big change in sound, but of course you'll get a little bit of a power bump as well because your exhaust flow is streamlined from the cats all the way back to the tips. Speaking of the tips you get four-inch polished stainless steel Borla exhaust tips, one of the best looking tips in my opinion coming out the rear end. Now, without further ado, we already got the car in the air, I wanna show you how this gets installed. Keep in mind there's a lot of rust, so you wanna have some PB B'laster and the appropriate tools on deck. Overall, I'd say one out of three wrenches for the guys out there using a lift, definitely making it a little easier. A soft two out of three for guys who might need to cut in order to get the ground clearance to get this thing out of here. Overall, about two to three hours from start to finish, so let's get to it. Tools used for this install are a hanger removal tool, PB B'laster or WD-40, power tool, and/or a ratchet, extension, 13 millimeter socket, 15 millimeter socket, swivel joint, and it's recommended to have a mallet or hammer on deck as well as a pry bar. Before we kick off our uninstall, I do wanna point out that the exhaust we're taking off of our New Edge today in the shop is not a factory exhaust. It's an older aftermarket one so it is a little bit rusty, we are gonna be taking those bolts out very carefully. They do have the tendency to break after 20 some odd years and we don't know how long this aftermarket exhaust has been on there, so it could be a little bit rustier than we expect. Hit it with PB B'laster or WD-40 to loosen things up, and we're gonna get to it. First thing we're gonna do for the uninstall is loosen the clamps on our over axle pipes, connecting them to our mufflers here. We're gonna do that on both sides with a 13 millimeter socket. Now, that those clamps are loose at the over axle pipes, I'm gonna use a hanger removal tool to pop our hangers out of the factory isolators here on the frame. Now, this is a tool that makes your life a lot easier, especially when things get a little rusty, can get a little hard to get out by hand. This can definitely come in handy, you can rent one at your local auto parts store if you don't already have one. Next up, we're gonna loosen up and remove our flanges connected to our mid pipe. Now, this is where things get a little bit rusty here. As you can see it is blacked out and rusted all hell, so we're gonna use our 15 millimeter socket, a lot of PB B'laster on these bolts I put on here. We're gonna try to break them loose. If you need to, you can always get a little bit more leveraged by attaching a wrench to the back of your ratchet here, and you can break them loose and then from there remove them. So, 15 millimeter socket, we're gonna remove these bolts. You can try to add a little bit more torque into the equation by using a power drill. Now, if you have air tools that can work as well, my fear is that if you use air tools, might be a little too much torque and break the bolts. So, we're gonna start slow, add our power tool into the mix here. The ratchet was doing the trick, it just takes a little longer and it's a little harder since everything's really rusty. So, power tools, let's see what it does. Rust is getting the better of us when it comes to taking off our muffler here, so what we're gonna do is take out the big gun, our Sawzall here, and cut right behind the muffler and in front of the over axle pipe just to get this thing off. We'll do the same thing on both sides. All right, now, that we cut our muffler system off all we have to do now is feed the over axle pipe over the axle and take it down. Now, as we're kicking off the install for the Borla Stinger S-Type Cat-Back on our New Edge, the first thing we're gonna do is off the car assemble this ball flange to the end of the over axle pipe and muffler system. That's gonna be all one piece unlike the cat-back we just uninstalled from our New Edge. This is all welded together, so we're gonna feed this over the over axle pipe. The muffler system is gonna lead back to our mid pipe, we have to attach this attachment piece with the ball flange before we go anywhere. So, grab one of the clamps included in the kit, feed it over your system here, attach that ball flange, bring it back down and tighten this clamp up. Now, you don't wanna over tighten this just yet, you wanna leave a little bit of room for adjustment so that once we get this on the car we'll be able to twist and turn everything as we need to to line it up. All right, now we can feed this over the axle and attach it to our mid pipe. Quick note here, as you're attaching your ball flange clamp from the Borla system to your factory mid pipe, you are gonna be reusing your factory hardware as far as the nuts are concerned, so if it is too rusty and it does break on its way out, you just wanna keep in mind you'll have to get a replacement set because they are not included in the kit. At this point you wanna tighten down the nuts here, not too tight, leave a little bit of room for adjustment until all your system is complete and then you can come back and torque everything down. But for now, just tighten them up just so they sit snug. All right, now we can do the same thing for the opposite side. It's about time to attach our tailpipe to the over axle pipe here. You wanna make sure you're using the correct clamps here because there are side specific clamps as far as over axle and mid pipe. Mid pipe clamps are gonna be a little bit smaller, just to clamp down a little tighter. This is a little bigger to accommodate for the bigger outlet. When it comes to attaching the tip here, all you have to do is slide this into the factory hangar, which is right above the cutout on your rear end. So, that's all we gotta do, so let's get to it. All right, now we can grab our 15 millimeter socket and tighten down that clamp. Now, we have both of our tailpipes attached and bolted down, we can go back through the entire system, torque down and tighten down all bolting clamps making sure there's no air leaks. Before you do so, since we did leave them for adjustment, you wanna make sure that your tailpipe tips are centered in their exit positions just to make sure it doesn't look a little goofy. Center everything up, get it where you want it to be, tighten everything down. All right, guys, that's gonna wrap up my review, install, and sound clip review of the Borla Stinger S-Type Cat-Back Exhaust, fitting all '99 to '04 GT and Mach 1 Mustangs. If you're looking for something a lot more aggressive than your factory sound without going too overwhelming, with the highest quality exhaust materials available on the market, the pretty affordable price tag, the Borla Stinger S-Type is definitely the way to go.

      Description

      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.

        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

      5 Top Rated Questions

      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!

      • 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.
