Borla ATAK Axle-Back Exhaust System for 2005-2009 Ford Mustang GT 4.6L V8 Automatic/ Manual Transmission Rear Wheel Drive; 2 Door Coupe; Convertible. (11806)

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.

ATAK, Acoustically-Tuned Applied Kinetics, 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. This is our most aggressive sound. Even though the sound on the exterior is uncompromising, the sound in the cabin is devoid of harsh resonance, a product of painstaking engineering and over 40 years of experience. Each system is built from premium T-304 stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer-controlled CNC manufacturing ensures an accurate fit. Best of all, BORLA stands behind every system with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.

Flavored Water I Actually Crave
Flavor Name: Best Sellers Variety Pack, Size: 16 Fl Oz (Pack of 12), Flavor Name: Best Sellers Variety Pack, Size: 16 Fl Oz (Pack of 12)
I didn’t expect to get hooked on a flavored water, but Hint Water Watermelon has honestly become one of my everyday essentials. I usually get bored with plain water, but this hits that perfect balance, it’s just enough flavor to keep things interesting without feeling fake or overpowering. The watermelon taste is super light and refreshing, like a subtle hint of a fresh slice rather than that overly sweet candy version you get with a lot of drinks. I’ve tried a ton of flavored waters, and this is one of the few that doesn’t leave any weird aftertaste, which is a huge win for me. I find myself reaching for it throughout the day, especially when I’m trying to stay hydrated but don’t want soda or anything sugary. It just feels clean and easy to drink. At this point, it’s kind of replaced most other drinks for me. I always make sure I have a few bottles on hand.

Great value for a quality brew - Dark Roast
Flavor Name: Dark Roast, Size: 24 Count (Pack of 1)
Have been buying a name brand at almost 2x the price. This is rich, bold, and flavorful. We like this dark roast coffee a lot. We will buy it again and continue enjoying these handy pods for our morning coffee.

Great coffee at a great price point.
Flavor Name: Dark Roast, Size: 100 Count (Pack of 1)
I priced these against the pods were were getting from big box and grocery stores and found these were slightly less expensive. Took a chance on these when I didn't have time to run to the store. My coffee connoisseur co-worker said they were the best we've had and our guests have commented on how nice the flavor is. For the price, you can't beat it.

A dark option.
Flavor Name: Dark Roast, Size: 100 Count (Pack of 1)
I decided to try this--I like a robust, rich flavored coffee. The color of Happy Belly Dark is good but the flavor a bit lacking for me.
