Borla ATAK Axle-Back Exhaust System for 2016-2020 Chevrolet Camaro SS 6.2L V8 Automatic/ Manual Transmission Rear Wheel Drive 2 Door Equipped With Dual Mode Exhaust (NPP) or Dual Split Rear Exit Bumper. BORLA System Does Not Include Valves. (11921CF)

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.

This system has dual tips and will fit vehicles equipped with Dual Mode Exhaust (NPP) but it does Not include Dual Mode valves. It may be used with the dual tip lower bumper cover to convert a single, split rear exit to a dual split rear exit. It features unique BORLA carbon fiber tips with bright centers. The ATAK is our most aggressive sounding system. BORLA Cat-Back and Axle-Back exhaust systems feature patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA Sound of Power respected by motoring enthusiasts everywhere. Each system is built from premium, high-quality T-304 austenitic stainless steel, superior to T-400 series knockoffs (such as 409), to give you the absolute best in performance and durability.

New Favorite Coffee
Flavor Name: Espresso, Size: 35.2 Ounce (Pack of 1), Flavor Name: Espresso, Size: 35.2 Ounce (Pack of 1)
Let me start out by saying I am a coffee fiend. I drink it all hours of the night and day and I've tried just about every brand you can think of. I took a chance ordering this and I'm so glad I did! Reading the other reviews helped me so I hope this helps someone else, too. No one is paying me for my opinion, I'm not getting a single thing for writing this except the satisfaction of reporting on a quality product. Not only is it a good price for how much you get, (09/25- $22 for 35.2 oz) but this is some of the smoothest coffee I've ever tasted. The beans are so shiny and just pretty. They're not all dried out and dull and dessicated looking like some coffees... The beans smell so good in the bag and even better once I've ground them. They grind up very quickly and easily too. There's no bitter aftertaste. Just pure, delightful, delicious coffee. I got the 5/10 espresso, and it's perfect for me. it's just strong enough. I like medium-strong roasts, so if you prefer darker or lighter roasts they have plenty of other options. I use both a drip coffee pot and a French press and this works beautifully in both. The crema in the French press is gorgeous. It's so far above other brands- even Seattle's best and eight o clock and Cameron's, which I thought I really liked... They don't hold a candle to this. I can't wait to try the other flavors.

Good Beans for Home Espresso
Flavor Name: Espresso, Size: 35.2 Ounce (Pack of 1)
I’ve been using these beans daily for about two weeks in my espresso machine, and they’ve been really consistent. The flavor is smooth and easy to drink, with a mild nutty note and low acidity. It’s not overly bitter, which I personally like for everyday coffee. One thing I noticed — you do need to dial in the grind a bit to get the best crema, but once you do, it comes out pretty nice. On the downside, the aroma and intensity are a little on the lighter side. If you’re into strong, bold espresso, this might not hit that mark. Overall, this is a great everyday option — especially if you want something smooth and reliable without too much bitterness. Good value for the size too.

Crisp, Refreshing, and a Family Favorite
Flavor Name: Kiwi Strawberry, Size: 16.9 Fl Oz (Pack of 12)
Propel Kiwi Strawberry is one of our favorites. It’s crisp, refreshing, and has just the right amount of flavor without being overpowering. The kiwi strawberry taste is especially enjoyable and makes it easy to drink throughout the day. We also like that it’s zero calorie and includes electrolytes and vitamins, making it a great option for staying hydrated during workouts or busy days. Overall, a consistently refreshing drink that we always keep stocked in the house.

Excellent product. But I thought they were expensive.
Flavor Name: Kiwi Strawberry, Size: 16.9 Fl Oz (Pack of 12)
This is a great product, great ingredients, excellent taste, sugar-free. My friend a actually came over and I think he drink most of them or took them home to his wife. Didn't last long and I thought they were pricey.
