How do I increase the horsepower in my Nissan GT-R?

I recently purchased a Nissan GT-R and I want to increase its horsepower. What are some recommended modifications I can make to achieve this?

One way to increase the horsepower in your Nissan GT-R is by adding a performance exhaust system. This will improve the exhaust flow and give your car a more aggressive sound. Companies like HKS and Akrapovic offer high-quality exhaust systems for the GT-R.

Another option is to install a cold air intake. This will increase the amount of air flowing into the engine, resulting in more horsepower. Some popular brands for the GT-R include AEM and Injen.
