What modifications should I do to boost the performance of my Nissan GT-R?

I recently purchased a Nissan GT-R and I want to make some modifications to enhance its performance. What are some recommended modifications that I can do without compromising its reliability?

One modification you can do is to install a performance exhaust system to improve the exhaust flow and increase horsepower. I would recommend the Borla Exhaust system.

Another upgrade that will greatly improve the handling and stability of your GT-R is adding a set of high-performance tires. Some popular options are Michelin Pilot Sport 4S or Pirelli P Zero.
