What is the best exhaust system for a Nissan GT-R?

I recently bought a Nissan GT-R and I am looking to upgrade the exhaust system for better performance and sound. I've heard mixed reviews about various options. What exhaust system would you recommend and why?

I highly recommend the Tomei Expreme Titanium Exhaust for your Nissan GT-R. Not only does it provide an aggressive and exotic sound, but it also reduces weight and increases horsepower. As an added bonus, it is also aesthetically pleasing with its burnt titanium tips.

I personally have the HKS Legamax Premium Exhaust on my Nissan GT-R and I am extremely satisfied with it. It provides a deep and throaty sound without being too loud. It also has a sleek design that complements the look of the car.

If budget is a concern, the Invidia Gemini Exhaust is a great option for your Nissan GT-R. It provides a subtle and refined sound, while still improving performance. It is also made with high quality materials and has a great fitment.
