Borla S-Type Cat-Back Exhaust System for 2011-2013 Chevrolet Silverado 1500/ GMC Sierra 1500/ GMC Sierra Denali 1500 6.2L V8 Automatic Transmission 2 & 4WD Crew Cab Short Bed (69.3")/ Extended Cab Standard Bed( 78.7"). (140437)

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.

The Borla "Cat Back™" name implies the exhaust system is located behind the factory catalytic converter where there factory emissions remain untouched and vehicle stays emissions compliant. This remains distinct from the Axle Back exhaust system that is located behind the rear axle. Alex Borla coined the phrase 'Cat Back' and introduced the Cat Back performance exhaust in 1978, a bolt-on replacement performance exhaust system requiring no welding, thus being secured using the factory hanger locations.

Borla Cat Back exhaust systems use engine-specific (not universal) mufflers that are designed, tested, and optimized specifically for a particular year/make/model vehicle. Borla Cat Back systems increase the overall sound level & performance. Vehicles that don't have a factory service-point require "cutting" the factory exhaust system before installing a Borla Cat Back performance exhaust system. Borla includes instructions where to make this cut and includes the hardware to complete the installation. Many 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 catalytic converter. A Borla Cat Back performance exhaust system replaces the factory exhaust system (behind this service-point) following the same exhaust path and secured using the original vehicle hangars and rubber isolators. Borla pioneered the automotive exhaust aftermarket in exhausts constructed in aircraft grade 304 stainless steel tubing, a material with higher content of carbon & nickel that won't rust or corrode.

Features:

  • Horsepower and Torque Increased by 7 – 10%
  • Increased exhaust flow for better performance
  • Better fuel economy at cruising speeds
  • The most aggressive sound of any Borla system

Fantastic for rough chewing
Color: Bule 0, Size: For Larege Dogs
Our big boy is rough with his toys and always seems to disintegrate his toys in seconds. I had seen this with hoping this will be the toy he doesn’t destroy. On day 2 now with the toy and he’s obsessed, even feel asleep with the toy in his mouth and still in one piece. Highly recommended for tough chewers.

Good but not for my dog
Color: A Red, Size: For Larege Dogs
Dog loves it but already falling apart. Can't seem to find a truly safe dog toy that won't come apart with my aggressive chewer. Had to toss it before pieces got ingested. But great toy in the begining. Just not safe for pit/staff type dog that destroy and chew.

Put your aggressive Chewer dog to the test!
Color: A Red, Size: For Larege Dogs
A very tough toy to stand up to my aggressive chewer lab! It's a great value! The squeak is not annoying, and she's got to clamp down hard on it. It's a nice throw toy! It bounces once or twice but it still brings out the pup in our Dog! Not too small a nice size for a Lab or retriever

A Hardy Toy for Chewers
Color: Bule Octopus, Size: For Larege Dogs, Color: Bule Octopus, Size: For Larege Dogs
I must say I was very surprised with the durability of this toy. We've had it for 3 days and not one puncture hole. My rescue is a destroy chewer that doesn't care for Hardy chew toys unless it squeaks. While the squeaker isn't the best, he still loves it. We put peanut butter in the grooves for him and he goes to town. Will purchase again should he ever destroys it, worth the price!

Durable toy for a great price! Will buy again.
Color: A Red, Size: For Larege Dogs, Color: A Red, Size: For Larege Dogs
Great toy, heavy, good size, and durable for active chewers. My two dogs like to play tug a war a lot and this toy has held up fantastically! Afterwards they tend to chew toys to pieces but this one has stood the test of time so far. Great buy!
