Borla ATAK Axle-Back Exhaust System for 2015-2020 Ford Mustang 2.3L 4 Cyl. EcoBoost/ 2015-2017 3.7L V6, Automatic/ Manual Transmission Rear Wheel Drive 2 Door EXCEPT Convertible and Active Exhaust Systems (4 tips). (11890)

BORLA® ATAK® (Acoustically Tuned Applied Kinetics) technology is designed for high-performance purists who prefer exhaust sound over their stereos.  ATAK®-equipped exhaust systems deliver the highest available dB (decibel) levels in the BORLA® street-legal lineup... and unlike inferior brands that lose significant sound quality at higher volumes, ATAK® is tuned like a graphic equalizer to shape and focus sound waves for optimum high-volume output.

ATAK® technology is based on specifically-tuned attributes of the internal muffler cores, which are calibrated on a vehicle-by-vehicle basis to deliver the most desirable sound. For more details and to hear the difference, watch our ATAK® videos below for different make and model vehicles.? The power of BORLA® Multicore® technology, with the sound of vehicle-specific acoustic tuning!

Upgrading your factory exhaust system to a Borla stainless steel performance exhaust system with a more efficient and less restrictive design can improve sound (adding more enjoyment driving your vehicle) and increase engine horsepower and torque throughout the RPM range (allowing quicker acceleration to pass a vehicle or get to highway speeds quicker). Borla offers Axle Back exhaust systems, Cat back exhaust systems, and for select Competition-Use-Only vehicles, we offer long tube headers to replace your exhaust manifold for the best performance and sound.

A Borla "Axle Back" or rear section exhaust implies the exhaust system is located behind the vehicle rear axle . Most installations are completed in less than an hour and require no cutting of the factory system. A Borla Axle Back performance exhaust is a less restrictive aftermarket exhaust system that will improve the sound level both inside the cabin and exterior. Borla Axle Back exhaust systems use engine-specific (not universal) mufflers that are designed, tested, and optimized specifically for a particular year/make/model vehicle. Improvements in sound and performance are accomplished by using a superior straight-through muffler design, mandrel-bent tubing, and the application of proper engine-matched tubing diameter. In some vehicles Borla offers multiple sound levels (Touring, S-Type, and ATAK®) to suite the individual driver's taste in vehicle sound. Borla also offers the Cat Back exhaust system which is located behind the factory catalytic converter.

Borla Axle Back systems replace the factory rear mufflers and exhaust pipe with an improvement in overall sound & performance to your truck, SUV, or car. Welded tips are standard on most systems running gas or diesel fuels. Some of today's modern vehicles have a factory service-point in the exhaust system (flange or slip-fit) located in the exhaust tubing behind the vehicle rear axle. A Borla Axle Back performance exhaust system replaces the factory exhaust system (behind this service-point) following the same exhaust path and secured using the original vehicle hangers and rubber isolators.

Vehicles that don't have a factory service-point require “cutting" the factory exhaust system before installing a Borla Axle Back performance exhaust system. Borla includes cutting instructions and hardware to complete the installation. Borla pioneered the use of aircraft grade 304 stainless steel tubing, a material with higher content of carbon & nickel that won't rust or corrode for automotive exhaust aftermarket.

helped treat my sore neck
Color: White-cooling Basic, Size: Camping Pillow(Pack of 1)
This pillow — after dialing in the right amount of shredded foam — has greatly helped my sore neck. Initially, I had to remove some foam. Then I gradually added foam until it reached optimum comfort and support. It is also CPAP-friendly — especially when I position my head near the pillow's edge. (I am a left-side sleeper.) I like the travel size because I use a bulky hugging pillow to ease stress on my shoulder and elbow. That makes my side of the bed feel cramped if using a larger head pillow. A smaller pillow is easy to flip end-to-end in the middle of the night. I have spent lots of money on pillows over the years, but this is the best I've ever had for relieving [1] neck pain and [2] CPAP mask seal problems. Very comfortable, supportive, and affordable. I did not notice any unpleasant smell — and I am usually sensitive to that kind of thing. Would highly recommend.

Love them!
Color: White-cooling Basic, Size: Queen(Pack of 2)
Love them! After 10 years with our MyPillows, they finally lost their fluff. The reviews I read of the MyPillows of today were not good; they didn’t have as much filling as they used to. These pillows remind me of how fluffy our new MyPillows were 10 years ago!! You sink right into them and can mush them however and they stay. These are way cheaper than the Coop and it’s the same concept; add or remove the filling as needed. The cooling side is a huge plus too! You won’t be disappointed with these pillows!

Great pillow, but the cooling effect depends on the cover
Color: Blue-ice Plus, Size: King(Pack of 2)
I really like this pillow overall. It’s comfortable, supportive, and feels well made. When you use it without a pillowcase, it definitely feels cool to the touch and does what it claims in terms of that initial cooling sensation. However, once you put a pillowcase on it, you can’t really feel the cooling effect anymore. I’ve tried multiple different pillowcases made from different materials, and none of them really let that cool feeling come through. That said, I still love the pillow itself. It’s comfortable and supportive enough that I’m keeping it. Just keep in mind that the cooling feature works best without a cover, which isn’t ideal for everyone. Overall, a good pillow — just manage expectations about the cooling effect once it’s covered.

Best Pillow Ever
Color: Blue-ice Plus, Size: Queen(Pack of 2)
Best pillow ever. Although it still gets "hot", it does take longer to get "hot". I love this pillow. I was buying a new pillow almost every 3 months. Other pillows would either remain rock hard or go flat. I was concerned at first when reading the description as I though the memory foam would be big pieces. They are soft fluffy pieces. I had to remove almost half of the foam to get the pillow to what works for me. I have not had to put any filler back in. Maybe in a couple of more months I may have to put a bit more in, but it is holding it's shape and not going flat. I do fluff it every night. This helps. I am a stomach sleeper. I have bought the expensive purple pillow and hated it so much I gave it to my daughter. This QUTOOL Pillow is the best! I bought a 2 pack. Have not used the other pillow yet, but I feel I may actually go years for once without having to buy a pillow as I have the 2nd one set aside if the first one gets to a point in need replacement. I have bought Dollar Store pillows. I have bought $300 pillows. None of them even come close to this pillow and the way you can adjust this pillow for you. The pillows came in a white mesh like bag. I keep all the unused "stuffing" in this bag. I have it hanging in my closet and I just fluff the bag once a month to keep the filling fresh so it is ready if and when I need it. Coming from someone who has trouble staying asleep, neck issues, a stomach sleeper who hate those flat pillows manufacturers think stomach sleepers like but actually hate, buy this pillow. Just buy it. Best Pillow for a picky person like me. Buy 2 or more so if you have to stay at a hotel, you can take your own pillow.
