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. 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.

not best quality, but does its job
Color: White
super easy to put up on the wall of my bedroom, and help it look less cluttered. appearance wise they look great, but quality wise one of the shelves was already starting to fall apart from the stand, almost as if it needed to be glued or secured better? it was super loose and kinda cheap feeling/looking just based on the one shelf falling apart. it's just okay.

Great Storage Solution
Color: White, Color: White
These 16’’ White Floating Shelves are truly wonderful for organizing and displaying items in any room. I’m currently using them in my craft room to store paint, and they have made it so much easier to keep everything tidy and accessible. The shelves are versatile enough for the bedroom, bathroom, living room, or nursery. Installation was straightforward and the shelves feel sturdy, holding a good amount of weight while maximizing wall space. I’m giving four stars because the finish isn't quite as clean as shown in the listing photos—there are some minor imperfections in the look. Just as a note, the picture I’m including is taken right after installation, before adding the finishing touches. You can see where there are gaps along the seams (not talking about between the two shelves). The shelves do come with stickers to cover the screw holes, but I haven’t added them yet. Overall, these shelves are a practical addition to any home.

Great quality
Color: Rustic Brwon, Size: 16in
Hassle but they work great. I love the color, the thickness and quality. They do have some weight but in my opinion, I prefer that. Right now the four shelves are holding up my WiFi routers and remotes. Will buy again
