Borla Stainless Steel S-Type 2-1/2" Cat-Back Exhaust System with 4" Black Exhaust Tips for all 2015, 2016 and 2017 GT Mustangs.

Even though you can tell there is a 5.0L V8 under the hood, the factory exhaust leaves something to be desired for your average muscle car enthusiast. Sadly, one of the first things you are bound to notice on your new 2015-2017 Mustang GT the moment you bring it home from the dealership is how quiet and tame it sounds. But…Borla has the solution!

Borla introduces their brand new S-Type Cat-Back system for all 2015-2017 GT Mustangs to help alleviate this issue. Manufactured entirely out of T-304 Stainless Steel, this 2-1/2" cat-back exhaust system will give you that perfect muscle car sound. This Borla Cat-Back exhaust system utilizes an integral X-pipe that will bolt directly up to your factory catalytic converters, keeping your Mustang 100% emission compliant. And the tuned S-Type mufflers with 4" black chrome tips not only sound amazing but will look great for the life of your Mustang.

Borla S-Type Cat-Back Exhaust System 140590BC Features and Benefits:
- Easy Installation, Bolts Directly to Stock Catalytic Converters
- Full Stainless Steel Construction
- Black Chrome 4” Angle Cut Rolled Exhaust Tips
- Borla Logo Embossed on each Exhaust Tip
- 2-1/2” Mandrel Bent Piping
- Straight Through Design with No Drone
- 30 lbs Lighter Than the Factory Cat-back System
- Utilizes an Integral X-Pipe  
- Reuses Stock Exhaust Hangers and Mounts
- Includes All Necessary Hardware and Instructions for Installation

*Fits BOTH Convertible and Fastback 2015-2017 GT Mustangs.

The factory exhaust is frequently the first item to get replaced in any new or classic Mustang restoration, and rightly so. The increased performance and better sound that you'll get from an aftermarket system usually far exceeds what the factory can offer. The products from Borla Performance Industries are some of the top exhaust systems available for your Mustang.

Order the Borla 140590BC Stainless Steel S-Type 2-1/2" Cat-Back Exhaust System with 4" Black Exhaust Tips for your 2015, 2016 or 2017 Mustang GT from CJ Pony Parts today!

We’re here with Borla's S-Type Cat-Back fitting your 2015 Mustang, now with black tips.

Regular viewers of our YouTube channel will know I'm a big fan of the Borla S-Type Cat-Back because that's what I run on my personal 2015 Mustang GT. When I originally installed it, my only complaint is I really wished it came with black tips. Well, now they're available. If you're looking for that S-Type sound for your 2015 Mustang, it's now available in the same system as before, same mufflers, same x-pipe, same high quality 204 stainless steel, and that killer S-Type sound now with a black chrome tip.

We're going to do a quick sound clip for you. We have plenty of sound clips of the S-Type with the polished tips. While I do believe the black ones look better, believe it or not, they don't sound any different.

Vehicle Fitment

This product will fit the following Mustang years:

Rated 5 out of 5 by from Best Sound for the 2015 Mustang I purchased my 2015 three months ago and was very disappointed and how soft the exhaust sounded. After weeks of frustration digging through online videos of exhausts I found that the Borla S-Type seemed to sound the best. After having this system on for a while I can tell you it is a winner! I have now listened to the Ford Racing Sport, Ford Racing Touring, and Borla Atak in person and I still believe the Borla S-Type sounds the best. Not to mention this exhaust will also save you around 2-3 miles per gallon. Bottom line: if you want a deep growl at the low RPMs and an aggressive rasp at the high, then this exhaust is for you.

Rated 4 out of 5 by from Decent quality Picked the Borla based on price, the black tips, and reputation. Installation is easy and the system went together really well. Quality is pretty good but the partially rolled tips are cheap looking (the finish is nice however). I prefer the Magnaflow beveled lip. I went middle of the road in the sound department with the S Type but it is still much louder than expected. There isnt any drone but you hear them at all RPM whether you're on power or off. I was hoping they would be quieter at highway speeds but that isnt the case. If that is a concern for you, dont pick the S Type. They sound alright, not spectacular but pretty good.

Rated 5 out of 5 by from A little loud but overall very happy! Ordered for my 2016 GT due to the stock exhaust being pretty weak. I have very little mechanical background but this was easy to install, just follow the instructions and watch the videos. When I first started my car, I got very worried that I screwed up by going with the S-Type. I knew it would be loud but it was significantly louder than I was expecting when I started the car. It warms up and quiets down after about 45 seconds of running. It's still louder than I would have liked but I have gotten use to it. When you want it to sound mean, it does! If I had to do it again, would have went with the touring model. Great sound though.

Rated 5 out of 5 by from Old School Sound The Borla cat back is well worth the investment. After installation the Colt became a Mustang. The sound, outside, is incredible when you fire it up. Definitely an attention getter. On the inside you hear a slight rumble with the windows up but put the windows down and you really can appreciate the sound that Borla was after and your after. The Black tips add a nice accent. Installation was a breeze. After jacking up the car the install took about 1(one) hour. Everything just bolted right up. I couldn't be happier with my investment.

Rated 5 out of 5 by from S-Type Goodness Finished the install yesterday and have been taking friends out for rides just to show off the exhaust. Very high quality product and easy install. Fit and finish are top notch. Oh...the sound. Tone is pitch perfect - good rumble at idle, pretty sedate at cruise, goosebumps at WOT and lots of spit and sizzle on trailing throttle. I'm still trying to get used to the volume level (my first Mustang). Really changes the character of the car bringing out the inner hooligan along with all the refinement.

Rated 5 out of 5 by from JUST WOW!! After watching video after video of sound clips I decided to go with the Borla system and couldn’t be happier. Installation took about 1.5 hours (no power tools and a tiny lift). The sound this system puts out is simply amazing!!!! You will drive with the radio off and windows down for the first few days just to listen to it. The black tips just set the car off nothing like black on black. Parked next to my buddies 2015 gt equipped with the Borla Ford Racing system he is wishes he got this system.

Rated 5 out of 5 by from Amazing exhaust! I bought this exhaust about a week ago and when I put it on, my initial thought was wow! It sounds amazing and looks great! The black tips really compliment my magnetic color mustang! I am really happy with the purchase, I would definiety buy again. It wasn't as loud as I thought after watching the videos but the sound is perfect. You won't regret getting the borla s type catback for your s550!!

Rated 5 out of 5 by from Excellent quality The fit and finish of the Borla S-Type is excellent and looks great with the black chrome tips. I was able to install it in the driveway with a pair of jack stands, a 3/8" ratchet and a flathead screwdriver. I did a lot of research before purchasing this cat-back system listening to several different clips and the Borla S-Type sounds amazing! Great muscle car rumble with the sporty sound from the X-pipe but still rather quiet on the highway. Two thumbs up.

Is this a "true dual" exhaust? Or do they combine in the midpipe?

Asked by: IG Stringer_s550
It is a dual exhaust.

The PO installed an H pipe and straight pipes. The drone cancels the stereo completely! The neighbors hate me! Like the sound of the Touring, but not crazy about installing a resonator back on the car. S-type may be too loud. Any thoughts between the two?

Asked by: CharlesS
It seems as though the S-Type would be the right choice in your situation.

2017 GT w/PP I'm down to 2 exhaust systems, the Borla S type & the Borla Atak. Want something aggressive like "hey my car will eat your lunch" but not "hey my neighbors really hate me." Listened to all videos and still having trouble deciding. Help,please

Asked by: JonE2GunZ
Out of those two choices and what you described you are looking for, Borla S-Type.
