Stage 4 Performance Pack, Performance Upgrade Silverado. They will all save you money by improving the vehicles performance and economy, now is the time to consider adding them to your vehicle purchase. The Stage 4 Performance Packs and prices vary on the brand and model of the vehicle.

Increasing the engines overall performance is something that would appeal to most vehicle owners. The stock factory intake system is a very restricting parts on your vehicle. This can happen by the limiting the amount of air the engine receives. Replacing the stock cold air intake alone will add a good amount of horsepower and torque.

This torque and horsepower you can hear and feel. Essentially, the more air the engine gets the more power it will produce. We currently offer four stages of performance packs. Each stage of performance provides progressively more performance than the previous one.

|  Supply:  $5295  | Delivery:  $120-150 | Installed: $5,795 |

If you want to finish off the performance pack nicely, this is how you do it.  Stage 4 comes with a stainless steel “pre-pipe” that connects directly the factory manifold.  Fitted with a high flow stainless steel muffler, this will give the car a more profound sound. The best description of this sound is a “deeper rumble”. Please note that performance in terms of power and torque will also increase but only marginally.
