Review & Install Video

Hey, guys. Stephanie with, here with a review of the Borla Touring Catback Exhaust system, fitting all 2015 and up V6 Mustangs. The Borla Touring Catback is going to be for the V6 owner out there that's looking for a high-quality system that's going to have a mellow, sleeper sound to it and that isn't over the top. This is more mild than some of the other options that are out there, like the Borla ATAK and even the S-Type. Borla has a lineup of three different catbacks for the S550 V6 Mustang, and they're all designed differently with different sounds for different tastes. When we rank them from most mild to loudest, the order would go the Borla Touring, which is what we have right here, then the S-Type, and then the loudest option is going to be the Borla ATAK. So this is going to be your quietest or most tame, but it's still going to be deep and louder than stock. All three of the Borla systems are going to offer about the same amount of horsepower, and they're going to open up about the same amount of restriction, and flow about the same. They're also made with the same materials, and other than the mufflers, they're going to have the same design. All of them, including the Touring, are going to replace everything from the resonator back. And Borla gives you their own mid-pipe resonator, as you can see right here. Now, this is a two-and-a-quarter-inch system, which is the same as the factory system, and this is mandrel bent stainless steel tubing. The system's made from T304 stainless steel, which is the highest quality material that you can get, and it's also been proven to be the best material for exhaust components. Then the system's finished with the mufflers, which we'll come back to, and then there's four-inch polished stainless steel tips that have the Borla logo embossed so that you have a nice, mean look to go along with the new exhaust tone. The difference in these systems is going to be the sound, which is derived from the different types of mufflers. Borla finishes this system with the Touring mufflers, which have a good amount of sound absorbing composite filament that's going to quiet the system down and it gives you a stealth sound. The Touring mufflers, while considered quiet compared to the S-Type and the ATAK, do still give a deep rumble and have a growl to them. It's more of a subtle sound than the other systems have, but it's still tuned and doesn't have a high amount of gurgle, and crackle, and rasp. This would be a good option for owners that really just don't want loud. So like I mentioned, the Touring mufflers are the tamest, for sure. I'd say that the sound that they produce is the deepest out of the entire Borla lineup, and they keep this deepness as the RPMs climb. There is some gurgle in decel but not much at all, especially when you compare it to the other two Borla systems. This system's for when you need your car to be fast but quiet, and I would describe it as a mild but definitely nice sounding tone. And like all of Borla's offerings, there is no distortion either. You can definitely hear a difference from inside of the cabin, even with the windows rolled up, but there is no drone though, so you don't have to worry about that. Overall, I'd say this has a nice note, something like a little growl without raspiness, like I mentioned earlier. As you guys heard in the beginning of this video, the sound is subdued but it's still a nice tuned note and it's not going to be confused with the stock exhaust. Now, with all of that being said, I'm going to give this a two out of five on the loudness scale, with one being a very quiet system and five being the loudest. But keep in mind that if you ever change your headers down this road, this could open up even more noise for you. So if your biggest deciding factor when shopping for a catback is volume, whether it be more or less, I'd say that you can find the loudest with the ATAK system and the quietest with the Touring here. Currently, Borla is the only company producing high-end catbacks for the V6 so naturally, they're going to be the highest priced. All of Borla's catbacks are in the same price range for the V6, which is right in between $1200 and $1300. There are other options from companies like MAC and Gibson that are available, and on average, those are costing in the price range of $800 and $900. So if the Borla is a little highly priced for you, then you can check out those other options as well. But just know that the quality, engineering, and fitment of those brands is probably not going to be on the same level as Borla, if that matters to you. When it comes to the install, you're going to be looking at an easy one out of three wrenches on the scale when we look at difficulty. You will be moving over your hangers to the new catback, so I'd recommend just taking those off with the factory exhaust when you drop that. It'll make the swap a little bit easier for you. This is considered a direct bolt-on item, so you won't need to cut anything or modify anything to get it installed. All that you're really going to need is a socket set, and a lift would certainly make things easier, but the job can be done on stands as well. You're going to be removing your exhaust from the resonator back, so an extra set of hands can make things easier for you here. The only other thing you'll reuse are the front clamps off of the resonator for your new resonator. When you go to install your new setup, as usual, it's probably a little bit easier if you start by hanging the mufflers first. And just in case you were wondering, the catback does come with two new sets of clamps for the rest of the system. You can figure on spending about an hour or two from start to finish to get all of this done. To wrap things up here with the Touring catback, this is more of a mild system, the quietest of the series of three systems that Borla produces, and it doesn't have drone or any type of sound distortion, even in the higher RPMs. It's also a high-quality system that's easy to install and it finishes with four-inch polished tips that look great out back of the S550. I'm Stephanie, and for all things Mustang, keep it right here at

Will lose my catalytic convertor?


  • This Borla Touring Cat-Back Exhaust will keep your catalytic converters intact and they will still be used in your exhaust system.

Can I expect to hear noticeable tops and burbles from this exhaust with stock headers and mid pipes without revving to the sky?


About how many HP gain you get out of it when you get it instated?


  • The Borla Touring Cat-Back Exhaust will only gain a few horsepower. Generally, cat-back exhaust does not add any horsepower. You will want to look into doing headers to really get power out of an exhaust.

Are these mufflers available in an axle back option. I'm looking for quality tone not loudness and these appear to be the highest quality, non-raspy, no drone product out there that will keep my neighbors talking to me. How important is the up front resonator?


  • We do not carry the borla touring exhaust in an axleback configuration at this time for a V6 mustang. The resonator up front is considered the first line of "muffler" on the stock 15-17 mustangs. This resonator is not needed and will increase sound once removed.

    The right sound for my 2015 3.7

    When I purchased this v6 it just did not have the right exhuast tone. I tried other set up's but ended with drone inside my stang and that was somthing i didn't want. This Borla Touring cat back is just what my 3.7 needed to solve the drone and give my stang the tone that it should have. Not loud, a nice growl when you start it up. Quite in the cabin during your drive and a stronger tone when you get into it. Adding this Borla package to my Roush CAI and BBK shorty headers gives this 2015 3.7 a step ahead of the 4.6's. And that's with no tune.

    Sounds great

    Great exhaust -- sound will make you think of the V8. I had these installed along with BBK shorty tuned headers at the same time. One caveat for convertible owners is that this can be fitted to your car, but it is not designed to fit -- and will not fit -- as perfectly as the stock exhaust. The convertible has additional structural braces that get in the way of install. I had a shop install and they were able to make it fit with a bunch of effort. It doesn't rattle, but you can hear it hit the brace on a hard bump. Props to Onsite Automotive in Stoneham, MA who were able to make this exhaust work with my car!

    Bolted right on the car, no adjustments needed at all. Sounds great, for my use, wouldn't want it any louder. Really fast shipping, it arrived the same day that I got my shipping notice.

    Better Than I Expected

    Don't think I could be happier. Installation was great, sound was exactly what I was looking for. I am making this mustang more of a sports car then a muscle car. This exhaust gives a great sound at start up for a V6. Normal driving no annoying drone...jump on it and you know it is not stock exhaust for sure....Overall... Exhaust note really perfect for curvy country roads.

    Borla Touring exhaust

    Just had the exhaust installed yesterday and it sounds great. Not too loud for the neighbors but has a good rumble at engine start and doesn't sound like a six. Barely can hear it with the windows up.
