    Drone?? It is hard to find good video/forum reviews with this Catback for some odd reason, Is there a drone on interstate running stock Midpipe?, I have read that the Borla Stinger has none. Thoughts and Concerns ?

    • The Borla Touring Cat-Back Exhaust has little to no drone. This is a less aggressive exhaust compared to the Borla Stinger.

    How does the Borla Touring sound compare to the Flowmaster Force II on a New Edge GT? Looking for a deep, high-quality sound that's on the mellow side.

    • Both the Flowmaster Force II Cat-Back Exhaust (99-04 GT, Mach 1) item #18426 ( and the Borla Touring Cat-Back Exhaust (99-04 GT, Mach 1) will have different sounds as Borla is more mellow whereas Flowmaster is more aggresive. If you do not see sound clips on our website, YouTube is a great source for clips of listening to exhausts.

      Borla Touring Exhaust - Wow!!!

      I replaced my MagnaFlow Exhaust with this Borla CatBack system. Wow, what a difference in quality and sound. I get compliments on it all the time, not to mention the 4" tips. Shipping was fast. Highly recommended. Thank you AM!

      Great Sleeper Exhaust

      Perfect tone/note. Not obnoxious but aggressive. Great fit and finish. You WILL need a lift. Can't get bends over axle on jack stands! Otherwise easy install. No drone.

      Best exhaust

      The Borla touring exhaust system more than met my expectations. The quality of 304 stainless steel tells me that this will be the last exhaust system I'll ever need for this car. The sound is perfect. No booming inside and the tone is deep and mellow. I highly recommend this system especially if you take longer trips and don't like the noise inside.

      2003 Mach 1 Automatic

      I bought this as a Mothers day present for my wife. We did not want anything that sounded too loud, unless we wanted it to. The Touring was the perfect system to install on the Mach 1. When you start up, it lets you know it is there with a deep tone. As you come off of idle, the system opens up, letting you know once again it is there. Once you get to cruise, it is hard to tell it is not the stock system. Just give it some throttle and she comes alive again. Great system. It took me and a friend about 2 hours to do this on jacks/stands. I would guess 45 minutes on a lift.

      Great Sound!

      I have a convertible 2000 GT, and these pipes are perfect. Not too noisy, just a nice burble until you step on it. But then still not too loud - just right. Great for the convertible.

      Fantastic Borla Quality

      My exhaust was in a bad way, so I opted to go for a replacement catback. I had previous experience with Borla so that influenced my decision a bit. Ordered it late on a Monday night and it arrived Thursday. This exhaust system is beautiful. It came packaged with extreme care and also included some small extras (decals, flex fit Borla hat) and was well put together. The clamps that are provided are very heavy duty and will work perfectly for a fast install. The fit and quality of this exhaust can't be matched. The tone is pure muscle car. Nice deep and throaty sound without being obnoxiously loud. It sounds great and I would recommend this product to anyone looking for great tone as well as a fantastic fit and finish! The 4 inch tips look amazing. Thanks AM!

      I bought this catback used off of a different mustang gt. got it home and took some scotch bright to it and it cleaned up to look like new even though it was years old. all stock clamps worked perfectly even after being used for a few years. sound is just perfect for a daily driven mustang. I would HIGHLY recommend borla, the quality is unmatched by any other exhaust company i've tried.

      Absolutely worth the money.

      If you want a great exhaust that sounds great and isn't just LOUD, get this exhaust. Build quality is excellent, the exhaust looks awesome, and its stainless steel so It won't rust out after a few years. You definitely get what you pay for when buying this.

      Blew away my expectations

      Thinking about a Borla catback? Do it. The fit, finish, quality of product, the company support, power and sound is incredible. Yes, it is more expensive, if you have the ability to is worth every dollar. I did a true dual exhaust project on a 2002 V6 3.8L Convertible Mustang with BBK ceramic shorty headers, Bassani C-pipe and Borla touring exhaust. The engine breathes and has incredible power. At idle, it sounds exactly like a V8. On takeoff, it has a very deep note that twists heads around looking at my car. From 30mph to 70, it sounds like a formula one car. Not kidding. However cruising on the interstate almost zero drone and pretty quiet. This is incredible. Sound performance under acceleration and quiet performance when traveling on a normal drive. If you knew what I now know, you would own it.

      Just the right sound

      This set up was perfect for me. Having a convertible didn't want something to loud. If I am cruising you wouldn't know its not stock. But once you open it up has a deep sound that you can tell is after market. Was just enough muscle car sound for me.
