Borla ATAK Axle-Back Exhaust System for 2011-2012 Ford Mustang GT/ 2012 Boss 302 - 5.0L V8 Automatic/ Manual Transmission Rear Wheel Drive; 2 Door Coupe; Convertible. (11791)

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.

BORLA has developed a revolutionary exhaust technology that enables our engineers to deliver unprecedented vehicle-specific control over the acoustical Note of an exhaust throughout the RPM range, while retaining 100% of the power-adding capabilities of BORLA's patented multicore design. Called ATAK (Acoustically-Tuned Applied Kinetics), this technology produces the highest available dB (decibel) levels in the BORLA street-legal lineup, and is designed for high-performance purists who prefer exhaust Notes over their stereos. The focus of ATAK is to pump the volume while retaining clarity of sound, avoiding distortion typically found in louder exhausts. With ATAK, the sound output is tuned like a graphic equalizer to shape and focus sound waves for optimum high-volume output. The development of each ATAK system begins with extensive study of each vehicle's acoustical properties. The technology is based on custom-tuned attributes of the internal muffler cores, which are calibrated on a vehicle-by-vehicle basis to deliver the most desirable sound. 'The distance from the exhaust manifold to the rear bumper, the shape of the underbody shielding, the amount of ground clearance, all these factors affect the sound, and they're different on each vehicle. With ATAK we take all this into account, and the result will blow you away, all with no drone inside the cabin of the vehcile' says company VP of Sales & Marketing, David Borla. Like all BORLA exhaust products, each system is handmade in the USA by master craftspeople and features premium, high-quality T-304 austenitic stainless steel construction, ultra-smooth mandrel bent piping, mirror-polished tips, and a Million-Mile Warranty.

Easy instructions, comfortable cushions
Color: Pink
I just put it together and I love it!!! It's so comfortable and it was easy to put together. You can rock it back and forth which helps your back. The seat is very wide and the cushion is thick. Pink is my favorite color, and this chair satisfies my pink obsession.

Wonderful chair
Color: Dark Black
I bought this office chair as a sewing tool, you might say. I felt that having an office chair on wheels would get me from the sewing machine to the ironing board and then to the cutting board and back to the sewing machine. I was having to get up and down to get around to all these places before and this saves me so much time and effort. I’m 71 so when the box came I was hesitant to try to bust into it and put it together but it went together so easily. It’s very comfortable and the lumbar support feels great on my low back. When I first sat down after the assembly process, the chair cushion tipped down in the front but after contacting the support team I was advised to tighten the tilt tension located under the chair and that fixed me right up! All and all, my chair is the perfect addition to my sewing area at a very affordable price. I couldn’t be happier!

Comfortable, affordable, and great for small spaces!
Color: Light Purple, Color: Light Purple
I had previously left a review of two stars, but have since deleted that review after I've owned the chair for a few weeks now. Initially, I stated the chair was uncomfortable and not cushioned at all. But this issue quickly resolved after sitting it for a longer time, it seems the cushion molds to you. So it may be uncomfortable the first few times sitting on it, but it eventually softens. The cushion is now soft yet sturdy. You don't sink in too much, but it's comfortable for sitting for long periods of time. I personally enjoy the mesh back as well, it supports my lower back and doesn't cause back pain. Normally I have to use a cushion of my own to support my lower back for most chairs, but this one actually supports me in a way that doesn't require an extra cushion - so that's really nice. The chair is fairly on the smaller end, which is perfect for low desks or tight spaces, which is exactly what I wanted. The height can be adjusted, but even at the highest setting, it is still fairly low. Keep that in mind - it may not be super comfortable for those over 6 ft. The arms flip up which makes storing it under a low desk very easy. The cushion is thick and very accurate to the picture. I love that it is lightweight and doesn't make much noise when rolling the chair. It also feels very sturdy. Some of the reviews say it feels flimsy, and I don't know if some are just assembling it incorrectly, because for me this thing is very strong and holds up quite nicely under my weight. Overall, this is exactly what I wanted for my personal living space. A chair that's not too bulky, but comfortable enough to sit in for long hours. It functions as advertised for this purpose. One final thing -- the color selection is gorgeous. I bought the light purple color and it fits my setup nicely! Color was accurate to the picture, and looks very cute and adorable in my space.

Surprisingly amazing chair!
Color: Pink, Color: Pink
tl;dr: If you need a chair that has the features of this one, then this one is a winner! Hits above its weight class for sure. My wife is 5’. She’s small. For whatever reason she ended up with a chair made for big people, like 6+ feet and up to 500lbs type of a chair. She’d often even sleep on it and chill on it. The chair was big enough to fit 2 of her to be honest. It was an expensive chair that I won at some raffle and didn’t like myself. Over the years it ripped (got a cover for it) and even started to get lopsided (from the sleeping) and finally a spring broke (hence the pillow on it in the pictures) She obviously lives pink. I also wanted to get a chair where she could work and not end ip asleep on. Not like we have a couch or a bed for that 😂. This chair is very obviously smaller than her previous chair, it’s also significantly cheaper in price and build, it’s also not as durable feeling or stable, and it’s just not as padded. Yet somehow it’s an amazing chair that we both like better than her previous chair??? Like it’s crazy that this chair somehow works better in so many ways. Her desk is modified to be shorter than normal desks (again, she small lol) and her previous chair was just too big. The wheels are also like SUPER smooth, like you can run a chair race easily with it. It rolls over her rug and tucks into her desk (which is in our bedroom) easily. The amount of space this has save us when the chair isn’t being used is a lot. Previous chair was much bigger and didn’t tuck in at all. The color is nice and the padding is plenty for a small and much lighter than 500lbs woman. I’m 6 feet and 200 lbs and the chair is nice for me as well. My chair is bigger and more secure in the backing, which is similar to this one. The lowest tension setting on my chair is still too high for her to lean back on my chair. This chair has a lower tension minimum and she can easily lean back freely, as well as keep enough tension to work without sagging. This chair is surprisingly outstanding! I’m sure my wife will destroy it quicker than the last one, but it’s so cheap that even if it only lasts 1-3 years, I’ll happily buy it ones or twice more 🤷🏽‍♀️. Maybe by then they’ll invent a comfortable titanium chair that’s affordable that she won’t destroy 😂.
