How can I improve the performance of my Nissan GT-R?

I recently purchased a Nissan GT-R and I'm looking for ways to increase its performance. Any tips or suggestions?

One way to improve the performance of your Nissan GT-R is by adding a cold air intake system. This allows for more air flow to the engine, resulting in more power.

Another option is to upgrade the exhaust system. This will not only improve the sound of your car, but also increase horsepower.
