How can I increase the horsepower on my Nissan GT-R?

I recently purchased a Nissan GT-R and I'm looking to increase the horsepower. I've heard about aftermarket parts and engine tuning, but I'm not sure where to start. Does anyone have any recommendations or tips?

The best way to increase horsepower on your Nissan GT-R is to invest in a high-performance exhaust system and upgraded intakes. You can also look into engine tuning and remapping for optimal results.

You can also consider adding a turbocharger or supercharger to your GT-R. This will significantly increase horsepower, but be sure to do your research and choose a reputable brand for the best results.
