Cold Air Intake and Cat Back Exhaust
I have not done the UpRev tune yet as the car only has 15k miles on it and that's the one piece that would void my warranty.
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. An engine is an air pump, and BORLA's exhaust system allows the engine to pump and flow more uninterrupted air. The actual horsepower increase depends upon the fuel management system's ability to provide the right amount of fuel to match the extra air flow; 5 to 15% increases are not uncommon. Under racing conditions, The Borla exhaust's actually make more horsepower than an open exhaust!
K&N performance air intake systems are designed to create a more aerodynamic path for airflow by removing stock intake tubing that can create excess turbulence, and by utilizing highly airflow-efficient filter media. Air first passes through a performance air filter—which is designed to provide more airflow than a standard disposable paper filter—before moving through an aerodynamically-engineered tubing system that helps keep airflow cooler and also helps provide a higher volume of air to the engine. Cold air is more dense than warm air because it contains additional oxygen molecules—allowing the cylinders to facilitate combustion more efficiently. A factory air intake often features tubes and baffles designed to muffle sound and typically feeds warm air to the cylinders, while K&N® performance air intake systems are designed to provide a smooth, unimpeded path for the airstream—keeping the airstream cooler and more oxygen-dense. With a K&N performance air intake system, you get a guaranteed increase in horsepower and torque.
The Wheel Horse Power has increased dramatically from these 2 upgrades. Understand that the 400 HP advertisement on these trucks is the flywheel HP not the wheel to surface HP as manufacturers always put the highest HP down to sell vehicles. But you can easily get over 400 HP wheel to surface with these 2 upgrades and I'm sure even more with the Up Rev tune.
Here are some photos post mod attached if I did it correctly.....
