Ultimately, the choice between the two will depend on your personal sound preference and how you want your GT-R to sound on the road or track.
Installation and Fitment
Both the Invidia and HKS turbo-back exhaust systems are designed for direct bolt-on installation, making them relatively easy to install for those with basic mechanical skills. However, professional installation is recommended for optimal fitment and performance. Here are some considerations for installation:
- Ensure you have all necessary tools and hardware before starting the installation.
- Follow the manufacturer’s instructions for proper fitment.
- Consider using new gaskets and hardware for a leak-free installation.
Both systems typically take a few hours to install, depending on your experience level and the condition of the vehicle.
Price Comparison
Pricing for turbo-back exhaust systems can vary based on the retailer and any ongoing promotions. On average, here’s what you can expect:
- Invidia: Priced around $1,200 to $1,500.
- HKS: Generally ranges from $1,500 to $2,000.
While both systems represent a significant investment, the performance gains and sound improvements can make them worthwhile for serious GT-R enthusiasts.
Final Thoughts
Choosing between the Invidia and HKS turbo-back exhaust systems ultimately comes down to personal preference, budget, and desired performance characteristics. Both systems offer impressive power gains, unique sound profiles, and high-quality construction. If you prioritize a more aggressive tone, the Invidia may be the better choice. Conversely, if you prefer a refined sound with solid performance, the HKS system could be the way to go.
Regardless of your choice, upgrading your GT-R’s exhaust system is sure to enhance your driving experience and unleash the full potential of this iconic performance car.
